Notes
1. The startup time might be longer in proportion to the number of drive trays connected. With a
maximum configuration of 1 controller and 19 drive trays, startup time is approximately 8
minutes.
2. Value of maximum configuration when all controllers and drives are mounted.
3. Mixing DBSD and DBLD drive trays might affect the maximum number of drives that can be
mounted.
4. If a drive is inserted into a slot of a dense intermix drive tray when the installed number of
drives exceeds 240 slots per path, the drive is blocked.
Cache specifications
Item
Specifications
Capacity (GB) 64 GB
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.
