To maintain a competitive advantage. and a management layer. Although a SAN typically references Fibre Channel.” Within this definition there is no mention of Fibre Channel. and computer systems so that data transfer is secure and robust.21 .Implementing MSA Storage Solutions Definition of a SAN A SAN is a dedicated. which organizes the connections. SNIA recommends using the term Fibre Channel SAN when the network is based on Fibre Channel technology. secure information infrastructure that enables direct physical access to common storage devices or a storage pool. it can be based on other technologies such as ESCON (Enterprise System Connection). storage elements. which provides physical connections. 1–4 HP Restricted Rev. centrally managed. “A network whose primary purpose is the transfer of data between computer systems and storage elements and among storage elements. 6.

Because of the size of IP networks. iSCSI can be used to transmit data over LANs. wide area networks (WANs). The iSCSI Protocol is an IP-based storage networking standard for linking data storage facilities. 6. Using IP-based storage allows customers to realize SAN functionality and benefits by utilizing existing Ethernet capabilities to store and retrieve data. translates Fibre Channel control codes and data into IP packets for transmission between geographically distant Fibre Channel SANs. iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances.Implementing MSA Storage Solutions SAN implementations from most storage vendors have been fairly simple—such as point-to-point configurations with a few switches between the servers and the storage. FC-IP (also known as Fibre Channel tunneling or storage tunneling) can only be used in conjunction with Fibre Channel technology. An iSCSI to Fibre Channel bridge (for example: the HP StorageWorks SR2122 Storage Router). Fibre Channel over IP (FC-IP). iSCSI is one of two main approaches to storage data transmission over IP networks. enables access to block storage on a Fibre Channel SAN across an Ethernet network. by increasing the capabilities and performance of storage data transmission.21 . 1–6 HP Restricted Rev. in comparison. The other method. iSCSI can run over existing Ethernet networks. Recent developments include: Fibre Channel extenders Fibre Channel-to-ATM gateways Fibre Channel-to-IP gateways SAN technology also includes the Internet small computer system interface (iSCSI) protocol. The iSCSI protocol is among the key technologies expected to help bring about rapid development of the SAN market. By carrying SCSI commands over IP networks. Rev. The benefits of a SAN include: Centralized storage — Consolidating storage (primary and secondary) in a SAN and sharing the resource across multiple servers reduces the cost of storage management. availability. providing maximum flexibility to accommodate business growth. Improved availability — Implementing advanced SAN designs enables faulttolerant and disaster-tolerant configurations that are ideal platforms for clustered. This support allows storage resources to be added or deleted without interrupting production environments.21 HP Restricted 1–7 . Bandwidth. mission-critical systems. The host initiates the process but another intelligent device. 6. such as the Network Storage Router (NSR). Elimination of server downtime while adding storage — Using Fibre Channelbased storage. the infrastructure can be changed as business needs evolve. transfers the data. thereby reducing downtime for storage changes. This capability allows storage to be added on an as-needed basis. resulting in improved storage utilization.Benefits of a SAN Benefits SANs reduce the cost of managing storage by consolidating storage and sharing the resources across multiple hosts. which offloads data from the network. redundancy. Online storage migration — Storage can be dynamically allocated and reallocated among hosts without interruption. Modular scalability — With modular scalability providing support for an unpredictable environment. and capacity can be dynamically scaled on demand. storage resources can be added or deleted without interrupting the production environment. Most Fibre Channel-based storage supports changes made to storage configurations through a host operating system. Serverless backup — Having serverless backup enables direct backup from disk to tape without going through the host. Scaling storage can be as simple as plugging a storage array into a switch or adding drives into existing storage systems. 21 . storage plumbing. The second tier uses software to provide value-added services that operate over the first tier. 6. This model definition clearly differentiates network attached storage (NAS) from SANs. as opposed to using device-oriented commands with SANs. 1–8 HP Restricted Rev.

Due to the shared nature of loop topologies.Benefits of a SAN SAN topologies SANs can use either Fibre Channel Arbitrated Loop (FC-AL) or Fibre Channel Switched Fabric (FC-SW) topologies. Configuring FC-AL in a loop topology presents several limits to the performance of the network because performance is affected by the number of devices attached to the loop. Access to the loop is determined by winning an arbitration to become the loop master. The most common topology used in the deployment of FC-AL uses a hub that forms a physical star interconnection.21 HP Restricted 1–9 . only one device may send data at any time. FC-AL The FC-AL network can be set up in two possible configurations—daisy-chained (loop) or through a hub. If a loop or non-responding device appears. the FC-AL hub will bypass the failure. the transmit port of one device is connected to the receive port of the next device in the chain. The preceding graphic shows the required components of a basic SAN based on an arbitrated loop topology. These components include: Host Host bus adapter (HBA) Storage subsystem 7.

Implementing MSA Storage Solutions FC-SW FC-SW is the abbreviation for the standard governing the form of Fibre Channel network in which nodes are connected to a fabric topology implemented by one or more switches. The preceding graphic displays some of the components of a basic SAN based on a switched fabric topology.21 . A fabric is a Fibre Channel switch or two or more Fibre Channel switches interconnected in such a way that data can be physically transmitted between any two N_Ports on any of the switches. In a switched fabric topology. 6. Each N_Port node of the FC-SW connects to an F_Port on a switch. many node-to-node connections can occur simultaneously.

Each zone set is assigned a unique zone set name when it is defined. You can perform zoning for the MSA SAN Switch 2/8 using either the Command Line Interface (CLI) or using this MSA Fabric Switch Management Utility. however. HP recommends that all your Fibre Channel devices be connected to the embedded switch when you configure zone members. Regardless of which tool you use. If a switch configured with zoning is added to a fabric that has no configured zoning. only one of these zone sets can be activated at a time. However. you must understand the following zoning elements before you begin to create zoning on a MSA SAN Switch 2/8: Zones — Logical entities that represent groupings of zone members. Internally the zone members are tracked by their WWPNs. The other zone sets can be used as backup. They define a zoning configuration.21 .

According to the experts. 6. this could mean the difference between keeping up or shutting down a business. that same administrator can manage up to four to six times that amount. In the preceding example. average direct-attached utilization rates are approximately 40%. 1 – 32 HP Restricted Rev. By consolidating storage. Storage consolidation saves money by creating a larger pool of storage for the hosts. resulting in unnecessary storage expenditures and added management expenses. With today’s rapid growth. both servers can have access to the same shared pool. it is easy to see that distributed storage can be wasteful. If both servers had 100GB of storage you needed to add 40GB to the server with 95% of its storage used. the benefits of storage consolidation for a company are huge.

This typically requires installing server-type licenses and software on each of these hosts. Routers are typically used for tape drives and libraries. which becomes a key requirement when consolidating backups across multiple servers. 6.Implementing MSA Storage Solutions There are several significant benefits to deploying a SAN-based backup solution: High Performance — The solution provides performance comparable to directattach solutions. SAN Management Software — SAN Management software is used to manage resources.21 . Router — Router (sometimes referred to as a bridge) device provides connection between Fibre Channel topologies and SCSI devices. Backup Software — Backup software is deployed on each of the hosts on a SAN that will perform backups. such as hub or switch Ethernet ports. This can be integrated with hostbased device management utilities or embedded management functionality. centrally located and managed hardware result in less administrative effort. It does this by presenting the SCSI devices as Fibre Channel devices to the SAN and then relaying Fibre Channel commands to these SCSI devices. security. Leveraged Investment — Tape drives and libraries are pooled. SAN backup components The key components SAN backup solutions add to the SAN are: Tape Library — Tape library and the tape drives it contains provide the offline storage for backup on the SAN. Scalability — Tape resources are pooled and shared across all hosts in the environment. Tape drives are not dedicated or locked in to specific servers as with direct attach backups. capacity is easily expanded by adding additional tape drives to the pool. Once the solution is deployed. The tape library provides automated tape handling. Flexibility — Backup capacity is readily allocated and reallocated as the environment changes.

Because of airflow considerations, HP recommends that a replacement part or appropriate blanking panel be available when a component is removed. The components listed below are hot-pluggable in the MSA1000. MSA1000 controller — If your system has two controllers, is in a multibus configuration, and one controller fails, you can remove and replace the failed controller without shutting down the system. Fibre Channel I/O modules — The Fibre Channel I/O module is a single-port, 2Gb Fibre Channel device that includes a 2Gb SW Small Form-Factor Pluggable (SFP) transceiver. This module can be removed and replaced with other interconnects. Refer to the MSA1000 User Guide for specific limitations when replacing hot-pluggable components. Power supplies — The redundant power supplies share the power load equally. Failure of one power supply results in the other assuming the full power load. A redundant power supply allows you to remove a power supply and replace it without interrupting system operation. Failure of a power supply does not necessarily mean the loss of the fan mounted on that power supply. Caution Removing a power supply or any other component significantly changes the airflow within the MSA products. The system will shut down in approximately five minutes if the removed component is not replaced or a blanking panel is not inserted. Cooling fans — The redundant fans share the cooling load. If one fan operates too slowly or fails, the other automatically operates at a higher speed. A failed fan can be removed and replaced while the system is running. SCSI disk drives ⎯ The SCSI disk drives can be removed and replaced as necessary. Drives should be removed and replaced one at a time or blanks should be placed in the drive bay if a drive is not replaced.

Traditional Power-On-Self-Test (POST) messages issued by PCI-based array controllers were combined with runtime event notification messages to create a new set of controller display messages. A complete listing of the new messages is found in the Modular Smart Array 1000 Controller User Guide, part number 347281-002. Control of the display is exercised through the use of four buttons located to the right of the LCD display.

Drives within the enclosures can be designated as part of an array.MSA1000 and MSA1500cs Management Utilities Background information on array storage systems Before going further. This reduces storage efficiency and increases cost per unit of storage. and multiple arrays can be created within an enclosure or between enclosures. within an array should be of the same size and type. For example. Mixing drive sizes causes inefficient use of storage space because the MSA controller uses space on a disk equal to that of the smallest drive in the enclosure or array. we will stop to define some of the terms and processes behind the operation of smart array systems. leaving a large amount of system capacity unused and inaccessible. One or more virtual drives can be created within the array storage capacity. (Virtual drives will be discussed separately.) Arrays are created by designating drives through use of a configuration or management utility. The discussion includes information on the following topics: Arrays Spare disks Logical drives RAID levels Expansion Extension Array migration Stripe size migration Selective Storage Presentation (SSP) Arrays Hard drives are installed in drive enclosures attached to the MSA controller. Rev. and therefore. Refer to the appropriate utility documentation for procedures for creating arrays. Array capacity equals the total capacity of all the drives in the array. The enclosures can be integrated (MSA1000 has one integrated enclosure) or external (the MSA1500cs and MSA1510i systems are connected to external enclosures). Drives within an enclosure. only 72GB of capacity on each 300GB drive will be used. the greater the number of drives in a logical drive. 6. in the unlikely event that another drive in the array fails while data is being rewritten to the spare. Logical drives When a storage system is initially configured. the logical drive will still fail. consider the number of hard drives to include. and storage efficiency needed for the type of data that will be stored on each logical drive. Two configuration tools are available to meet your requirements: striping and the use of Redundant Array of Independent Disks (RAID) levels. I/O performance. the greater the performance level that can be achieved. As a general rule. However. If a spare is present and a physical hard drive fails. while other configurations methods offer better I/O performance or storage efficiency. 4–8 HP Restricted Rev. Striping will be discussed in this section and RAID levels in the next section. When planning your logical drives. The system uses the mirrored or parity information from the other member disks to reconstruct the data onto the spare drive. the physical hard drives can be grouped into as many as 32 logical drives. empty disk within an enclosure that is not an active member of any particular storage unit. the performance considerations are offset by fault tolerance consideration–the greater the number of drives in a logical drive. Depending on your needs and storage capacity. Some configuration methods offer greater fault tolerance. HP recommends including enough hard drives in your enclosures to allow some of the drives to be used as spares. The process of rebuilding the information onto the spare begins automatically. the higher the probability of one or more disk failures in that logical drive. Spares are designated using configuration or management utility applications. Spare drives should be of the same size and type as the other disks within the enclosure. the spare automatically replaces the failed drive as a member of the logical storage unit. It can be designated as a spare for one or more arrays. determine the importance of fault tolerance. the physical hard drives are grouped into one or more arrays. When planning the best way to configure your storage. The available space within an array can be divided into logical segments called logical drive units.Implementing MSA Storage Solutions Spare drives A spare drive is an extra. However.21 . Efficiency is degraded by the extra time it takes for reads/writes to be requested or written to multiple enclosures and buses. data is lost without the ability to recover it.MSA1000 and MSA1500cs Management Utilities Striping Striping refers to the physical location of the hard drives that are included in a logical drive unit. A minimum of one hard drive is required to create a RAID 0 logical drive. but at the price of I/O performance and slightly less fault tolerance. with no fault tolerance built into the logical drive. A different RAID level can be assigned to each logical drive unit within an array. 6. RAID 0 RAID 0 is striping only. The five RAID levels are explained below. but at the price of storage efficiency. Horizontal striping allows for the creation of large logical drives and efficient use of storage capacity.21 HP Restricted 4–9 . If one physical drive within the logical drive fails. Two types of striping are available. Horizontal striping – Includes hard drives contained within the same storage enclosure. RAID levels Fault tolerance can be built into your array system by designating a RAID level for a logical drive unit. none is needed for fault tolerance All data on the logical drive is lost if a physical drive fails Cannot use an online spare Can preserve data only by backing it up to external drives Disadvantages • • • Rev. A RAID 0 logical drive is useful for rapid storage of large amounts of non-critical data or when cost is the most important consideration. Advantages and disadvantages are: Advantages • • • Highest performance method for writes Lowest cost per unit of data stored All drive capacity is used to store data. Vertical striping – Includes hard drives from separate storage enclosures and across different SCSI buses. Vertical striping offers good fault tolerance and performance. This recovered data is usually written to an online spare in a process called a rebuild. performance. 6. The blocks of parity data are distributed over every physical drive within the logical drive. In each mirrored pair. When a physical drive fails. also known as Distributed Data Guarding In RAID 5 a block of parity data is calculated for each stripe from the data that is in all other blocks within the stripe. In this configuration. This configuration is useful when cost. it is referred to as RAID 1+0. Advantages and disadvantages are the same as for RAID 1. the data blocks are striped across half of the drives in the array and then the drives are mirrored in pairs. the remaining drive in the mirrored pair can provide all necessary data. In this configuration. and data availability are equally important.21 . This fault-tolerance method is useful when high performance and data protection are more important than the cost of physical drives. Several drives in the array can fail without incurring data loss. the physical drive that is not busy answering other requests answers any read request sent to the array (called load balancing). data that was on the failed drive can be calculated from the user data on the remaining drives and the parity data. A minimum of two drives is required for RAID 1. This RAID level requires a minimum of three drives. Advantages and disadvantages are: Advantages • • Highest read and write performance of any fault-tolerant configuration No loss of data as long as no failed drive is mirrored to another failed drive (up to half of the physical drives in the array can fail) Expensive (many drives needed for fault tolerance) Only half of total drive capacity is usable for data storage Disadvantages • • RAID 1+0 When a RAID 1 array has more than two physical drives.

Configuring management and data ports The controller connects to the network switch from its Ethernet iSCSI module. In dual controller configurations, two modules are required and ports on both modules must be configured. Consider the following points when configuring management and data ports. Isolate management traffic from storage traffic by assigning IP addresses in different LAN segments. Assign one (or more) IP address to each port, then assign one (or more) TCP portal to each IP address. Enable or disable management services, as needed. The services and their default settings are listed below. • • • • • TELNET (default: disabled) SSH (default: enabled) HTTP (default: enabled) HTTPS (default: enabled) SNMP (default: enabled) Assign IP addresses and TCP portals to data ports in accordance with the Path/accessibility diagram Note The maximum number of supported IP addresses and portals might differ, depending on the storage system and the controller model. Refer to system user documentation for more information. 5 – 32 HP Restricted Rev. 6.21 MSA1510i Management Utilities Configuring hard drives There are two steps to configuring hard drives: create arrays and create logical drives. Both of these steps are covered in a lab exercise. There are a number of considerations when configuring hard drives. The SMU does not support SCSI and SATA enclosures in the same array. Hard drives in an array should be of the same size and speed. For best performance, include drives from different enclosures and connected to different SCSI buses on the array controller. Consider reserving some drives for use as online spares. When using spares, consider the following: • • A spare must be the same type (SCSI or SATA) as other drives in the array. A spare should be the same size (or larger) and speed (or faster) as other drives in the array. Using smaller/slower drives reduces performance of the array should the spare become active. A hard drive can be assigned as a spare to more than one array. If a spare is assigned to an array, the words “with Spare” are included in the array description. • • Configuring storage targets Configuring storage targets requires the completion of several steps. Create the target Create portals assigned to the physical ports Create target portal groups Assign portals (from the same physical port) to the portal group Map logical drives to the target Configure the redundant controller, creating a second portal group bound to the target and a portal off of the second controller A lab exercise will take you through these steps.

The success of a multipathing solution depends on identifying each device within a network and identifying if multiple paths go to the same device or different devices. Load balancing is used to maximize throughput between server and storage. This joint solution allows vendors to design hardware solutions that are tightly integrated with the Windows operating systems and enables Microsoft to correctly accommodate the nongeneric characteristics of each vendor’s storage device. Microsoft Multipath Input/Output The Microsoft Multipath Input/Output (MPIO) driver software supports only Windows operating systems and is supported on all three of the MSA array systems discussed in this training. MPIO also enhances system performance by performing load balancing when multiple data paths are available. a server sending I/O requests down several paths might operate with very heavy workloads on some paths while other are underutilized. MPIO automatically routes data to a functional path to ensure data availability. Upon detection of a failure of any of those components. Microsoft includes in its sample generic DSM source code a means of deriving one. does not form a complete solution. If the DSM returns a path that is inactive. Since not all vendors assign their devices a unique hardware serial number. Each vendor’s load balancing policy is set in the DSM. Without multipathing software. vendor-specific mechanisms can be implemented in the DSM. The software is integrated into Windows 2000 Server and Windows Server 2003 operating systems. 6. MPIO determines which paths to a device are in an active state and can be used for load balancing. MPIO is designed to monitor the health of system components between hosts and storage – adapters.Implementing MSA Storage Solutions Multipathing application/drivers The MSA1510i uses Microsoft MPIO drivers for multipathing. The MPIO software supports the ability to transparently balance I/O workload without administrator intervention. Alternatively. MPIO initiates the failover process.21 . by itself. such as serial numbers. MPIO solutions are designed to work in conjunction with device-specific modules (DSM) written by vendors of storage hardware – the MPIO software. 5 – 46 HP Restricted Rev. MPIO uses standard information obtainable from the hardware itself. and switches. using other SCSI INQUIRY data. This policy determines how the I/O requests are actually routed. and the bus driver. the DSM makes a determination. as to which path the request should be sent. including device-specific initialization. DSM management Management and monitoring of the DSM can be done through an administrative utility. 6. Each DSM plays a role in a number of critical events. the miniport driver. The preferred interface is through the Windows Management Instrumentation (WMI).21 HP Restricted 5 – 47 . Device initialization Each DSM is contacted in turn to determine whether or not it provides support for a specific device. request handling. the port driver. the DSM shifts to the error handling mode. the disk class driver. Only the version intended for a particular storage product should be used. There are different versions of the DSM for the MSA1000/MSA1500cs and the MSA1510i. If the I/O request cannot be sent down a path because the path is broken. the disk-driver replacement. In the case of fatal errors.MSA1510i Management Utilities MPIO drivers The MPIO driver package consists of three multipath drivers: the port filter driver. making failover necessary. it indicates whether the device is a new installation or the same device previously installed but which is now visible through a new path. all of which are implemented in the kernel mode of the operating system. based on its internal load balancing algorithm. Rev. paths are invalidated. Error handling The DSM determines whether to retry the I/O request or to treat the error as fatal. The driver package works in combination with the Plug and Play Manager. Device-specific information is abstracted and exported to the bus driver and to the disk objects under its control. MPIO DSM The MPIO driver package contains generic code for vendors to adapt to their specific hardware device so that usage and performance of the device can be improved. If the DSM does support the device. and error recovery (retrying and failover). and the request is rebuilt and transmitted to a different device path.
