EVA4400 Continuous Access overheat

[wai perng]

Hi!
Anyone has the exact figure/ percentage of the CA overheat?

I notice I have 'lost' 200Gb (out of my total 8 * 146Gb FC disk) just to create a DR Group. Is this normal?

I tried to look for Whitepaper & Best practices but find none.

Thanks!

You mean overhead, I guess...

The answer is in

HP StorageWorks Enterprise Virtual Array compatibility reference

Page 29

By default, with recent firmware versions, the EVA reserves 100 GB in RAID 1 (hence 200 GB in raw space) for the default DR group log file size.

You can change this value, with a minimum of 5 GB.

Hi!

Thanks for the infor.

Is EVA uses this 100Gb for the 'write history log'? Where can I change the default allocated size?

Wai,

You can assign the log disk size when you setup the DR group. Afterwards you can change it at the source side of your DR groep (second Tab, Logging).

[Dileep..]

we can change the size of the log disk. To change the log disk location we need to delete and recreate the DR groups.
