Symmetrix V-Max Series with Enginuity Overview

Time to update the blog. I’ll post my notes from EMC World 2009. Here’s the first of the series.

V-Max SE (single engine)

Matrix Interface Board Enclosure (MIBE)

Scaling up – growing from a small configuration to a large configuration

Scaling out – growing out beyond the physical backplane

V-Max Engine

  • Host and disk IO ports
  • Multi-core storage CPUs
  • Mirrored global memory
  • V-Max interconnects
  • Enginuity storage OS

The global memory is distributed across all V-Max engines.

V-Max system

  • Scales 1-8 engines
  • 2-16 director boards
  • 128 FC FE ports
  • 64 FICON
  • 64 GigE/iSCSI
  • 1TB memory
  • 10 storage bays
  • 96-2400 drives
  • Engines go from 1 to 8 from bottom to top
  • Director boards go from 1 to 16 from bottom to top
    • Engines are inside out
    • 7-8 are the first two directors for engine 4
    • 16-15 are engine 8?
    • 1-2 are engine 1?

V-Max system – one engine (120 drives)

  • 2 directory boards
  • 16 FC FE
  • 8 FICON
  • 8 GigE
  • 128GB memory
  • 120 drives
  • Expansion bay to grow to 360 drives
  • V-Max engine 4 is the only engine
  • Director boards 7-8

V-Max Engine

  • 2 director boards
  • Redundant power supplies
  • Redundant battery backup
  • Redundant management modules
  • Front-end connections for hosts
  • Back-end connections to drives
  • Multi-core CPU
  • Global memory
  • Redundant connections to the V-Matrix interconnect
  • Back-end
    • Contains 4 back-end I/O modules and supports redundant direct connection to 8 drive enclosures
    • Supports dual initiator failover across directors
    • Supported drives
      • 200GB/400GB EFD
      • 146GB/300GB/450GB 15k
      • 300GB 10k
      • 1TB SATA
  • Front-end
    • FC 2/4 Gb for host and SRDF
    • FICON 2/4 Gb for mainframe
    • iSCSI/GigE 1 Gb for host and SRDF
    • iSCSI/GigE also has hardware compression
  • Memory
    • 32GB
    • 64GB
    • 128GB
    • Upgrade within an engine or add another V-Max engine
    • Memory is mirrored across engines through the V-Max interconnect
  • 4 cooling modules and redundant power supplies
  • 2 director boards in each engine, one even and one odd (odd is lower board, even is higher board)
  • FA ports (odd ports are on the right, even ports are on the left)
  • Systems is designed to be able to tolerate a single engine failure (when there are more than one)

V-Max Matrix Interface Board Enclosure (MIBE, pronounced mi-bee)

  • Supports up to 16 director boards
  • 1U, each sits side by side
  • A fabric and B fabric to redundantly connect all engines together

Configurations

  • Backend cards and V-Max cards are not configurable
  • IO modules are configurable
    • All FC
    • All FICON
    • All iSCSI
    • FC and FICON (FC, EF, FC, EF)
    • FC and GE (FC, GE, FC, GE)
    • EF and GE (EF, GE, EF, GE)
    • Memory (32GB, 64GB, 128GB)
  • Direct connect to 8 DAEs
  • Daisy chain to 8 more DAEs (up to 2 DAEs chained for 3 total DAEs per loop, hence 3 * 8 * 15 = 360 360 drives)
  • Base Configuration
    • 8 DAEs in the system bay
  • 1st Daisy Chain
    • 8 DAEs in the expansion storage bay (4 on the bottom row Q1, 4 on bottom row Q2)
  • 2nd Daisy chain
    • 8 DAEs in the expansion storage bay (4 on the top row Q1, 4 on the top row Q2)
  • First 4 engines support two direct connect drive bays (480 drives)
  • 1 level of daisy chain drive bays can be added to these engines (960 drives)

Direct connect needs to be close

Daisy chain bays can be geographically dispersed

Director board

  • Two quad-core (one disk, one host)
    • H,G,F,E (front-end, host)
    • D,C,B,A (back-end, disk)

Questions

What’s the speed of the V-Max Interconnect?

What’s the maximum distance for dispersion? 73 inches for DMX, 146 inches for V-Max (you can disperse any/both daisy chain bays, and it does require an RPQ).
