Good day all.
Well I have joined the club and am now the proud owner of a Supermicro 45 Bay JBOD Expansion Server Shelf 847E16-RJBOD1 with ~30 drives and ~460TB. Currently have it hooked up via 2 SFF-8088 to SFF-8088 cables to a LSI 9201-16e 6Gbps 16-lane external SAS HBA installed in my "server".
This is replacing my previous setup with the same "server", 2 x LSI 9201-16e 6Gbps 16-lane external SAS HBA cards with 8 x SFF-8088 to 4 SATA cables running to 8 x RSV-SATA-Cage-34 that are/were on a couple of shelves.
Been up and running for about a week and thoughts so far are:
- It looks cool in the 4-post 42U rack
- It is loud! (I knew it was loud but that holy s#$% moment when you first power it up)
- snapraid backup/scrub is only happening at about 2/3 the speed of before (sort of knew this as well)
- that was a lot of screws to remove the drives from the RSV caddies and screw them into the JBOD caddies.
- It looks cool!
As mentioned, I have it hooked up via 2 SFF-8088 to SFF-8088 cables, one for each backplane, and am wondering if I can hook up the other 2 SFF-8088 ports on the JBOD with two more cables to get some additional speed. I did read the manual it it discusses the other two ports are used for daisy-chaining but you never know.
Not being one to let well enough alone, I am now on the journey to repackage my two "servers", one from above and the other used for acquiring linux ISO's, into a couple of 2U cases so I can get them nicely into the rack.
For the latter, am thinking about a RackChoice MicroATX/Mini-ITX 2U Rackmount Server Chassis as I am running a mitx MB and a couple of 3.5 drives and a couple of SSD's with no add-on cards so should fit just nice.
For the former, the "server" hooked to the JBOD, I am looking at this RackChoice 2U Rackmount Server Chassis as it allows full height cards to be used via PCI riser so I can keep using the HBA card I already have. The other option I am looking at is picking up a LSI SAS 9300-8e 12Gb/s SATA/SAS and a couple SFF-8644 to Mini SAS SFF-8088 cables and a 2nd RackChoice MicroATX/Mini-ITX 2U Rackmount Server Chassis but I am not sure if the SAS3 HBA is backwards compatible with SAS2 backplanes.
Anyway, the adventure continues ....
Thanks
