Do you have a link to a sample of such enclosure?
In or via Europe for example there is Fantec brand
They have e.g. 8-bay enclosure with usb3 and esata via portmultiplier
backplane or something
Look for FANTEC QB-X8US3-6G
There is also a 4bay case by them
I am not in for the speed, so mdraid software based with single esata
and port multiplier would suffice for me as I am not in for high speed
reads or writes, but I am looking into a robust and resilient setup
which is not too complicated.
robustness/100% availability.. what I also recommend
is as much
redundancy as possible.
e.g. on one server I have 2 S-ATA controllers, in total 12
3.5" harddisks using these backplanes
, to keep HDDs hot swappable.
each mirror on one controller. In past I had a controller failing (i
think it was bad cabling (of one hdd, but affected whole controller) one
time and a bug in the kernel module the other time. with raid 10 setup
half of the disks failed, but the array kept running.
redundant power supply will be the next step.
