Repository
When performance management is being performed, based on the type of target (ETERNUS DX60/DX80/DX90), the number of logical units involved, and the number of DE (Disk Enclosure), the required capacity given below becomes necessary.
(2) * (240 + (1.2 + 0.3 * number of DEs + 0.3 * (number of LUs + number of RAIDGroups[*1])) * (86400 / 60) + (95 * number of DEs) + (50 * (number of LUs + number of RAIDGroups[*1]))) / 1024 + 9 * (10.6 + 0.07 * (86400 / 60)) / 1024 [*1] The "number of RAIDGroups" is the number of RAIDGroups created from the LUs. |
Example
When performing performance management of the ETERNUS DX80 system with 512 logical units, the following capacity is required.
(2 * (240 + (1.2 + 0.3 * 2 + 0.3 * (512 + 64)) * (86400 / 60) + (95 * 2) + (50 * (512 + 64))) / 1024) + (9 * (10.6 + 0.07 * (86400 / 60)) / 1024) = 549.1314MB
Type of Express | CPU requirement | Memory requirement |
|---|---|---|
Express Web GUI | 2.0 or more | 1024 or more |
