    Chapter 1 Introduction The XL-RAID-2804ISSA RAID Subsystem XL-RAID-2804ISSA connects to the host system in iSCSI interface. It can be configured to any RAID level. XL-RAID-2804ISSA provides reliable data protection for servers and the RAID 6 function is available. The RAID 6 function allows two HDD failures without any impact on the existing data.

    VG share the same RAID level, but may have different volume capacity. Cache Volume. XL-RAID-2804ISSA uses the on board memory as cache. All RAM (except for the part which is occupied by the controller) can be used as cache. User can divide the cache for one UDV or sharing among all UDVs.

Global Spare disks. GS is shared for rebuilding purpose. If some VGs need to use the global spare disks for rebuilding, they could get the spare disks out from the common spare disks pool for such requirement.

  • Page 11: Raid Concepts

    1.4 RAID Concepts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive. The array of drives appears to the host computer as a single logical drive.
  • Page 12 Definition of RAID Levels RAID 0 is typically defined as a group of striped disk drives without parity or data redundancy. RAID 0 arrays can be configured with large stripes for multi-user environments or small stripes for single-user systems that access long sequential records. RAID 0 arrays deliver the best data storage efficiency and performance of any array type.
  • Page 13 the information recorded on the remaining drives. Records typically span all drives, which optimizes the disk transfer rate. Because each I/O request accesses every drive in the array, RAID 3 arrays can satisfy only one I/O request at a time. RAID 3 delivers the best performance for single-user, single-tasking environments with long records.
  • Page 14 RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information to the physical drives in the array. With RAID 6, however, sets of parity data are used. These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives.

  • Page 15: Raid Management

    RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Level Description Min. Drives Block striping is provide, which yields higher performance than with individual drives. There is no redundancy.

  • Page 30: Quick Install

    E.g., user chooses RAID 5 and the system has 6*200G HDD and 2*80HDD inserted. Then if using all 8 HDD for a RAID 5, the volume max size will be 560G (80G*7). But XL-RAID-2804ISSA will do a smarter check and find out the most efficient use of HDDs. This results in using only the 200G HDD (Volume size is 200*5=1000G).
  • Page 31 Step 2: Please select a LUN number. Access control of host would show as a wildcard “*”, which means every host can access this volume. In this page, the “Volume size” can be changed. The maximum volume size is shown. To re-enter the size be sure it has to be less or equal to maximum volume size.

    H. Installation Steps for Large Volume (TB) Introduction: XL-RAID-2804ISSA are capable to support large volumes (>2TB) on all product lines. When connecting XL-RAID-2804ISSA to 64bit OS installed host/server, the host/server is inherently capable for large volumes from the 64bit address. On the other side, if the host/server is installed with 32bit OS, user has to change the block size to 1KB, 2KB or 4KB to support volumes up to 4TB, 8TB or 16TB, for the 32bit host/server is not LBA (Logical Block Addressing) 64bit supported.
