Table 2.3 Capacities required for servers on which to install Express

Type of Express	Memory requirement (Unit : MB)	Disk space requirement (Unit : MB)	Remarks
Express Manager	128	1792 + (A)	See "Repository".

Repository

When performance management is being performed, based on the type of target (ETERNUS DX60, DX80/DX80 S2, DX90/DX90 S2), 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
