EVA 4400 disks configuration

Hello,

We have EVA 4400 with 2 enclosures M6412A with 8 FC disk per enclosure. We need to enlarge our storage either for static data and dynamic. So we decide to buy another 4 enclosures M6412A. 2 enclosures with 16 disks FC 450GB 15K for dynamic data, and 2 enclosures with 16 disks 1TB FATA for static data. We would like to add FC disk to existing Disk Group with FC disks, and create new Disk Group with only FATA disks. Is this configuration is properly, safe and will not lower efficiency ? Thanks for reply.

Re: EVA 4400 disks configuration

In fact it is required that you create a new disk group for the FATA disks. You cannot have 15K disks and FATA disks on the same disk group.

Adding more disks to the dynamic disk group will give you more performance.

I recommend to obtain better performance you should rather distribute your disk groups across all your enclosures as evenly as possible instead of having two enclosures dedicated to FATA and the other four for FC.
