RAID specifications

D: Data drive, P: Parity drive.

Although the storage system with a configuration of RAID 1, RAID 5, or RAID 6 provides data reliability enhanced by redundancy, there is a chance that user data could be lost due to an unexpected host, storage system hardware, or software failure. Therefore, users are requested to back up all data.

SAS, SAS 7.2k, flash drives mounted

RAID 1

2D+2D, 4D+4D

Specification

Capacity (GB)

NAS module Cache Capacity

DDR3 DIMM 8GB x 12 [Slot]

Note

  • All 12 slots must be fully installed with DIMMs.
  • Each DIMM is replaceable when they fail.
  • The DIMM is not common and cannot be used with DKC DIMM.

Control method

Read LRU, Write after

Battery backup

Provided

Backup duration

Unrestricted (saving to a nonvolatile memory)

Data in the cache memory is preserved against power failures. If a power outage occurs, data in cache memory is written to drives.

When the storage system enters Cache Backup mode, the amber WARNING LED goes on to when the system starts. This warning indicates that the battery charge has dropped significantly and the remaining battery capacity is not sufficient; the storage system will continue operating with the Write Cache function disabled.

When the battery is charged, the warning indication disappears, and the storage system continues the operation in the Write Cache function.

The warning indication disappears within six hours. Even when the warning is shown, normal operation is assured in Write-Through. Read and write performance is lowered because the Write Cache function is disabled.

If the storage system is not charged for more than six months, the battery can become overcharged and sustain unrecoverable damage. To avoid this situation, charge the battery more than 3 hours every six months.
