●Open Volume QuickOPC not for OPC Restoration case (S3)
M:Resolution
(The same value as used in the device. Set to "1" if possible.)
C3:Copy capacity for QuickOPC on Open Volumes (*1) [GB]
(where QuickOPC is not used for OPC Restoration)
N3:Number of sessions for QuickOPC on Open Volumes
(where QuickOPC is not used for OPC Restoration)
S3 [MB] = ((2 × C3 /M) + N3) × 2 × 8 [KB] / 1024 (Round up decimal point)
●Open Volume QuickOPC for OPC Restoration case (S4)
M:Resolution
(The same value as used in the device. Set to "1" if possible.)
C4:Copy capacity for QuickOPC on Open Volumes (*1) [GB]
(where QuickOPC is used for OPC Restoration)
N4:Number of sessions for QuickOPC on Open Volumes
(where QuickOPC is used for OPC Restoration)
S4 [MB] = ((2 × C4 /M) + N4) × 3 × 8 [KB] / 1024 (Round up decimal point)
*1: For EC, OPC, QuickOPC, SnapOPC, or REC copy sources, the copy capacity is the total capacity
of all volumes (slices or partitions) in the ETERNUS DX400/DX8000 series that are defined as
copy sources. For REC copy destinations, the copy capacity is the total capacity of all volumes
(slices or partitions) in the ETERNUS DX400/DX8000 series that are defined as copy destinations.
If the same ETERNUS DX400/DX8000 series is used as both an EC, OPC, QuickOPC, SnapOPC,
or REC copy source and a REC copy destination, the copy capacity value is the total capacity of all
copy sources and copy destinations.
If the multi copy function is used, add the total capacity of the multi copy source volume (slices or
partitions) × the number of volumes in the multi copy destination for each multi copy source.
(Example)
• Multi copy target area in copy source volume A: 200 [MB]
Number of multi copy destination volumes: 4
• Multi copy target area in copy source volume B: 500 [MB]
Number of multi copy destination volumes: 8
Capacity of multi copy source = 200 [MB] × 4 + 500 [MB] × 8 = 4800 [MB]
→ Add the 4800 [MB] calculated above to the copy capacity C1 or C3 according to the copy type.
(For EC/OPC/SnapOPC/REC, add the value to C1. For QuickOPC, add the value to C3.)
Add the number of multi copy sessions to N3 when using QuickOPC, or to N1 for other copy
functions. In this example, add [12 (= 4 + 8)] to the number of sessions N1 or N3 according to the
copy type.
(For EC/OPC/SnapOPC/REC, add the value to N1. For QuickOPC, add the value to N3.)
For OPC Restoration on a multi-copy, select one of the copy destinations and apply the OPC
Restoration formula. QuickOPC should be preferentially used if it is one of the multi-copy types.
The other copy destinations should be calculated as normal multi-copy sessions.
