In this post we will discuss components of EMC Symmetrix DMX-4. EMC Symmetrix DMX-4 consist of 1 System Bay and (1 upto 8) Scalable Storage Bay’s. Each Storage Bay can hold up to 240 Disk Drives totaling 1920 drive in 8 Storage bays or 1024 TB System. Systems with special requirements can be configured to 2400 drives instead of standard 1920 drives. The primary bay is the System Bay which includes all directors, service processor, adapters, etc, while the Storage Bay contains all the disk drives, etc. System Bay (1 Bay) Channel directors: Front End Directors (FC, ESCON, FICON, GigE,iSCSI), these are the I/O Directors. Disk directors: Back End Directors (DA), these control the drives in the System. Global memory directors: Mirrored Memory available with DMX-4, Memory Director sizes range from 8GB, 16GB, 32GB or 64GB totaling 512GB (256GB mirrored). 1920 total in the system. Environmental monitoring is used to monitor all the VPD (Vital Product Data). 146GB and 200GB available. power on/off. 15 drives per enclosure Battery Backup Unit (BBU): 8 BBU modules per Storage bay. Power supplies: 3 Phase Delta or WYE configuration. drives. that is the interface between directors. between 3 to 5 mins of backup power in case of a catastrophic power failure. 8 BBUunits. Video. 240 per bay. 1TB and now EFD’s 73GB. Storage bay (1 Bay Minimum to 8 Bay’s Maximum) Disk drives: Combination of 73GB. they provide an interface to connect disk drives through the storage bays. 2 XCM located at the rear of the system bay. if the color of the LED is green. UPS: UPS for the Service Processor Silencers: Made of foam inside. diagnostics and configuration purposes. FICON. 15 drives per Enclosure. GigE.2K SATA are all compatible.Disk adapters: Back End Adapters. the speed is 4GB. 450GB. 500GB. Cooling fan modules: 3 Fans at the top of the bay to keep it cool. 15K. Zone A and Zone B based Power Supplies. cache. 7. Display and Mouse. Speed: 10K. Communications and Environmental Control (XCM) modules:Fabric and Environmental monitoring. 2 in total. maximum 8 of them in the system bay. Power distribution units (PDU): One PDU per zone. Channel adapters: Front End Adapters. each BBU support 4 Drive enclosures . If the color of the LED lights on the drive is Blue its 2GB speed. 400GB. 2 in total. ESCON. 300GB. call home. Power distribution panels (PDP): One PDP per zone. 146GB. Used for remote monitoring. Battery backup Unit (BBU): 2 Battery backup modules. similar type drives. This is the message fabric. etc. main power. iSCSI). Drive Enclosure Units: 16 per Storage Bay. Service processor components: Keyboard. different Silencers for System and Storage bay’s. they provide an interface for host connection (FC. each RAID Group and each drive enclosure should only have similar speed drives. .
