8.2.20 Assign REC Disk Buffer
This function reassigns REC Disk Buffers to an REC Buffer.
■ Assigning an additional REC Disk Buffer
The procedure to assign additional REC Disk Buffers to an REC Buffer is as follows:
Procedure
1 Select the REC Buffer, to which the REC Disk Buffer is to be assigned, and click [Assign REC
Disk Buffer] in [Action].
• The REC Disk Buffer can be assigned to an REC Buffer only when the REC Buffer's usage is "Send".
• The following number of REC Disk Buffers can be assigned to one REC Buffer:
- ETERNUS DX90 S2/DX410 S2: One or two REC Disk Buffers
- ETERNUS DX440 S2: One, two, or four REC Disk Buffers
- ETERNUS DX8100 S2/DX8700 S2: One, two, or four REC Disk Buffers
• A single REC Disk Buffer cannot be assigned to multiple REC Buffers.
• When assigning multiple REC Disk Buffers to an REC Buffer, each REC Buffer has the following
requirements.
- The assigned REC Disk Buffers have the same drive type
("Online" REC Disk Buffers and "Nearline" REC Disk Buffers can be assigned in the same REC Buffer.
However, only assigning either "Online" REC Disk Buffers or "Nearline" REC Disk Buffers is recommended
since the available capacity and access performance may be reduced when these REC Disk Buffers are
used together.)
- The assigned REC Disk Buffers have the same number of drives (four or eight)
- The assigned REC Disk Buffers have the same encryption status ("CM", "-", or "SED")
• When assigning an additional REC Disk Buffer, use one with the same capacity. When using REC Disk
Buffers of different capacities, the smallest becomes the standard, and all other REC Disk Buffers are
regarded as having the same capacity as the smallest REC Disk Buffer. In this case, the remaining REC
Disk Buffer space will NOT be used.
When assigning REC Disk Buffers to REC Buffers, an REC Disk Buffer must be created in advance. Refer to
"8.2.21 Create REC Disk Buffer" (page 362)
for details.
