HP EVA 4000/6000/8000 Series - Part 01

Physical layout of the solution
Operational overview
• First generation EVA
   – Dual fabric
   – Dual loop
   – One mirror port
• Second generation EVA
   – Up to four fabric connections per controller
   – Two mirror ports
   – E-PBC I/O module for drive bypass
   – Different fabric connections

Feature comparison of controller:

• Business Copy (BC) V3.0 — improvements
– Three-phase snapclones
– Replica resynch
• Replication Solutions Manager V1.1 and 1.2
– GUI that uses job engines and wizards to support CA and BC
– Included with either CA or BC

Licensing
• Basic XCS license is not required
• Command View EVA V4.X — paper
– Options for EVA4000, 6000, or 8000
    • 1TB increment
    • Unlimited capacity use per EVA
    • Upgrade up to unlimited capacity use per EVA
    • Optional licenses for the EVA — enforced TB limits
– Business Copy EVA
– Continuous Access EVA
– BC and CA licenses entered through the SMA or server
– Licenses purchased for use with XCS V5.020 work with XCS V5.030

Storage system menu:
OCP menu tree has added Host Port Config, I/O Module Config, Loop Recovery Config, Unbypass Devices, and Mastership Status under System Information

Host ports
• Same design as the first generation EVA (remain at 2Gb/s)
• High configuration has four per controller, not two
• Clean up on host modes
   – Remove unnecessary functionality
• Active-active (AA) multipath is default
• Support for direct connect to HBA (all switch or all direct)
   – No SAN switch required (therefore, no CA support)
   – HBAs must support FC-AL
   – Low and middle configurations can support 2 hosts, 2 HBA ports each
   – High configurations can support 4 hosts, 2 HBA ports each
   – Command View must be available on direct-connected servers to allow EVA management

Device ports
• Same number as first generation EVA for all second generation EVA configurations
• Remain at 2Gb/s
• Use Tachyon DX2 input-output processor (IOPs)
• Loop position attribute
   – Viewable with Command View EVA V4.X
   – Sequential loop position of the ports for all controller and disk drive nodes
   – Physical position of device on the loop as seen from the reporting controller

Mirror ports
• Two mirror ports per controller
– One additional mirror port for the HSV2x0 controller (HSV1x0 has only one mirror port)
– All configurations (EVA8000, EVA6000, EVA4000)
• Two ports allow FC to run at full duplex (send/receive simultaneously)
• Enables higher write performance

Serial ports
• Uses Quad UART (QUART) — first generation EVA uses dual UART (DUART)
• Three of four serial ports available
   – UART (DB9) — Console port access operates same as first generation EVA
   – Dual controller interconnect (not used on first release)
• Controller-to-controller communication path
• Uses 26-pin mini-D connector
   – AUX (DB9) — No planned use

Dual controller interconnect
• Not supported for first release of the second generation EVA
• Cable that connects controller to controller
• Allows easy transitioning to second controller after failure
• Carries signal for PowerPC to PowerPC on a UART
• Provides status and reset/interrupt interfaces
• Has three signals for monitor and kill
