Thanks for the replies, to answer the questions:
Noise/power are considerations as it's destined for home - I don't have WAF issues, but I try to remember it's not a DC.
Budget for a shelf is up to £600ish, i’d like dual
PSU, current preference is a DS4243 which start around £200, a 4246 would be nice, but it's top end of the budget and realistically unraid on mechanical drives will be fine with IOM3 and a module upgrade could happen later if I jump to something more IO focused e.g FreeNAS etc.
RU wise i'll be ordering in a suitable 8-12U and adding switch/patch and hopefully a little 10Gb action.
Usage is Unraid (so IT mode) with (up to) 28 data drives, 2 parity drives, additional drives will be passed to VM's, but are likely to be SSD's so housed in a GL380 G7 or possibly an R710, it makes more sense to keep SSD IO local.
Capacity wise i'll only be buying 8TB drives this time round. In the past few years i've built 5 storage servers, this will consolidate all of them
and some other things that are used occasionally.
MSA60 looks viable, it seems I may need an HP RAID card to upgrade firmware, or at least flash a compatible card to think it’s HP branded? Feedback says it’s loud, as long as i can swap fans out without it getting bent out of shape it may be a decent shout - the kids have ear defenders from my mining days
I currently run a 13 drive desktop set-up and will have finished the 12 disk expansion pod build next week. Just waiting on an H200e and cables to connect the additional 12 bays up. My limited experience of older disk shelves was they could be noisy/hot/power hungry, occasionally having hardware array size limits (non issue as JBOD/IT mode) or clipped individual drive sizes at a certain size or worse yet were picky about drives/drive firmware and as I plan to use SATA rather than SAS, the less picky, the better.
