    T10 Protection Information T10 Protection Information (PI) is an end-to-end data integrity feature of the PERC H730P card. When PI is enabled, the PERC H730P provides additional protection against silent data corruption, and ensures that incomplete and incorrect data do not overwrite good data.

  • Page 16: Disabling T10 Pi

    NOTE: An even number of drives is required to create RAID 10 virtual disks. 4KB Block Size Disk Drives PERC H730P card supports 4KB block size disk drives, which enables you to efficiently use the storage space. NOTE: Mixing 512–byte native and 512–byte emulated drives in a virtual disk is allowed. But, mixing 512–byte and 4KB native block size drives in a virtual disk is not allowed.

  • Page 17: Configured Spin Down Delay

    During full initialization, the host cannot access the virtual disk. You can start a full initialization on a virtual disk by using the Slow Initialize option in the Dell OpenManage storage management application. For more information on using the BIOS Configuration Utility to perform a full initialization, see Initializing Virtual Disks.

  • Page 18: Background Initialization

    Background Initialization (BGI) is an automated process that writes the parity or mirror data on newly created virtual disks. BGI does not run on RAID 0 virtual disks. You can control the BGI rate in the Dell OpenManage storage management application. Any change in the BGI rate does not take effect until the next BGI run.

    Solid State Drives (SSD). The Dell PowerEdge RAID Controller (PERC) H730P supports FastPath. To enable FastPath on a virtual disk the Dell PowerEdge RAID Controller (PERC) H730P cache policies need to be set to Write-Through and No Read Ahead. This enables FastPath to use the proper data path through the controller based on command (read/write), IO size, and RAID type.

    Summary Of RAID Levels Following is the RAID levels supported by PERC H730P cards: • RAID 0 uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy.

  • Page 98: Disk Mirroring

    For example, in a four-disk system using only disk striping (used in RAID 0), segment 1 is written to disk 1, segment 2 is written to disk 2, and so on. Disk striping enhances performance because multiple physical disks are accessed simultaneously, but disk striping does not provide data redundancy. Figure 6.
  • Page 99 The parity data is distributed across all the physical disks in the system. If a single physical disk fails, it can be rebuilt from the parity and the data on the remaining physical disks. RAID level 5 combines distributed parity with disk striping. Parity provides redundancy for one physical disk failure without duplicating the contents of the entire physical disks.
