Hi,
I have a business opportunity which would involve a large amount of
storage, possibly growing to 10TB in the first year, possibly more. This
would be to store media files - probably mainly .flac or .mp3 files.
Concurrency wouldn't be particularly important as I'd be the only person
access the storage and I have no need for lightning speed.
It would be nice to be able to start smallish and grow as required, but
my experience of linux raid to date is that it's not possible to resize
arrays. (I have a 1TB array built from 6 x 250GB SATA discs on Promise
SATA150 TX4 controllers).
Can anyone offer recommendations as to the most cost-effective way to
achieve this sort of storage?
Are there any limitations I might run into using md on Linux?
For example, suppose I get something like this [1] and throw in an
appropriate mobo/processor etc and 24 x 500 GB SATA discs; would
md/mdadm be able to create a single 11TB RAID5 partition, ie (23-1) x
500, with a hot-spare? Would this be a sensible thing to do?
What about file-system limitations, e.g. would ext3/reiser/XFS support
an 11TB partition?
Would I be better off creating smaller volumes combining them with RAID0?
I'd appreciate any tips/suggestions/advice/pointers to further sources
of information.
Thanks,
R.
