Data Stripping

Given you have choice of lay out data, striping... 250 GB- 10 file systems - 25 GB each what would you do?

Re: Data Stripping

Coming from SAN/NAS?? What level on SAN/NAS??
If coming from SAN/NAS, it may already be stripped. Why strip again??
Just distribute it over different controllers to optimise i/os.

Say you have 2 controllers - x and y
now for file system1- put primary control x and for file system2 primary controller y and so on for other file systems.

Re: Data Stripping

Hi Vaibhav,

The advice will depend upon the no. of device which gives you this 250Gb space. Are these LUNS from some storage? If yes what is done at storage level to get these LUNs? Is redundancy taken care at storage level itself?

HTH,

Re: Data Stripping

LVM stripped across 15 disks. Instead of Stripped disk if the client would ask for Mirroring ? what would you do?

Re: Data Stripping

If these are locally attached and this is an important production system then extent based striping (mirrored stripe) is about the only the way to go.

The config would depend on how many controllers you have and the config/ type of the storage.

If this is SAN based storage then a different story may apply.

Give more details and will provide better advise.
