  • Page 105: Managing Spares

    SM can use a global spare to reconstruct the critical array (see page 85). When a drive fails, the EF2800 looks for a dedicated spare first. If it does not find a properly sized dedicated spare, it looks for a global spare.

  • Page 106: Enabling Dynamic Spares

    For example, if you enable Dynamic Spares and a drive fails, you can replace the drive and the EF2800 will rescan the bus, find the new disk drive, and automatically start reconstruction of the array. You do not have to assign the new drive as a spare for the reconstruct to start.

  • Page 107: Managing Dedicated Spares

    Adding a Dedicated Spare You assign dedicated spare drives to a specific array. If a member drive in the array fails, the EF2800 uses a dedicated spare drive to automatically reconstruct the array. You can add dedicated spare drives to redundant arrays (mirrored [RAID 1 and RAID 10] and parity [RAID 3, RAID 4, RAID 5, and RAID 50]).

  • Page 108: Managing Global Spares

    If a drive in any redundant array fails, the EF2800 can use a global spare to reconstruct the array. If a global spare is too small (smaller than an individual member in an array), the array cannot use it.

    The redundant information lets you restore user data if a disk in the array fails. The host system views the EF2800 system as a single FC disk drive. It is actually an array of physical disks behind a RAID controller. The EF2800 system is managed by software to appear as a single, very large physical disk.

  • Page 209: Array Types

    The fault tolerance of a RAID 0 array, therefore, is less than that of any single disk in the array. The term RAID 0 is widely used for these arrays, however, because they are conceptually similar to true RAID applications. DataDirect Networks EF2800 FC RAID Storage System User Guide (V 1.0)

    RAID 4 is similar to RAID 3 in that the redundant information is achieved in the form of parity data. The user data is distributed across all but one of the disks. The EF2800 uses a single, dedicated parity drive for data protection. The main difference is that RAID 3 usually synchronizes writes to its disks, while RAID 4 can send data to its disk independently.

    You can change one additional EMP setting—polling interval. This is the interval, in seconds, that the EF2800 polls the EMPs for status changes. If the polling rate is set to zero, the EF2800 does not communicate with the EMP. Only use this setting if you suspect you are having communication problems with the EMP.
