  • Page 34: System Architecture Overview

    System architecture overview This section briefly describes the architecture of the Hitachi Unified Storage VM storage system. Note: The HUS VM is an “open systems” only array. Mainframe systems are not supported. Hardware architecture The basic system architecture is shown in the following diagram.

  • Page 35: Array Groups And Raid Levels

    HUS VM storage system. It is a set of four physical drives installed into any disk trays (in any “roaming” order on HUS VM). When a set of one or two such Array Groups (four or eight drives) is formatted using a RAID level, the resulting RAID formatted entity is called a Parity Group.
  • Page 36 2nd drive failure in the other stripe. In Hitachi RAID 1 (RAID 10) where we have a stripe of mirrors, if two drives fail in different mirror pairs, then each mirror pair is still alive within the stripe and thus no data is lost.

  • Page 37: Raid 5

    (or seven) data chunks and one parity chunk. Each chunk contains 768 logical blocks, because HUS VM supports only open systems. The enhanced RAID 5+ implementation in the HUS VM minimizes the write penalty incurred by standard RAID 5 implementations by keeping write data in cache until an entire stripe can be built and then writing the entire data stripe to the drives.
  • Page 38 Write penalty of RAID 5 is larger than that of RAID 1 because pre- update data and pre-update parity data must be read internally because the parity data is updated when data is updated. Hardware architecture Hitachi Unified Storage VM Block Module Hardware User Guide...
  • Page 39 SCSI address, so that it has a TID and logical unit number (LUN). Figure 2-3 Sample RAID 5 3D + 1P Layout (Data Plus Parity Stripe) Hardware architecture Hitachi Unified Storage VM Block Module Hardware User Guide...

  • Page 40: Raid 6

    Sequential data striping The enhanced RAID 5+ implementation on the HUS VM attempts to keep write data in cache until parity can be generated without referencing old parity or data. This capability to write entire data stripes, which is usually achieved only in sequential processing environments, minimizes the write penalty incurred by standard RAID 5 implementations.

  • Page 41: Ldev Striping Across Array Groups

    LDEV striping across array groups In addition to the conventional concatenation of RAID 1 array groups (4D +4D), the HUS VM supports LDEV striping across multiple RAID 5 array groups for improved logical unit performance in open-system environments. The advantages of LDEV striping are: •...

  • Page 42: Systems Operations

    Figure 2-5 LDEV Striping Across 4 RAID 5 (7D+1P) Array Groups All data drives and device emulation types are supported for LDEV striping. LDEV striping can be used in combination with all HUS VM data management functions. Systems operations This section provides high-level descriptions of HUS VM systems compatibility, support, and configuration.

  • Page 43: Systems Host Platform Support

    The global cache feature in HUS VM enables any fibre-channel port to have access to any logical unit in the storage system. In the HUS VM, each logical unit can be assigned to multiple fibre-channel ports to provide I/O path failover and/or load balancing (with the appropriate middleware support, such as HGLAM) without sacrificing cache coherency.
