Hi,
I could use some advice with my home build. I was going to pick up 6 more M.2 NVMe SSD’s and then I saw a post on here and I realized, once again, that I am probably about to make a bad bang for the buck decision.
tl;dr Are there data center pull’s of NVMe drives that are of good quality and speed? I am budgeting ~$120/ea (6 total), top priority is speed and then size. Price is a bit flexible and I already have 2 x 256GB MyDigital ones.
Going by the many posts I have read while lurking, similar to some others on here I started with a desktop PC and loaded it up with HDD’s to make a ‘server’. It become unmanageable and along the way I ended up with a 4 post rack and a real server. My current setup is based around a Norco case with 20x3TB in RAID6 and dual E5-2670 in an ASRock MB.
I am very attached to Windows Server 2016 and I would like to keep using it. I tested a hyper converged setup with two servers and I really liked it so I decided to move to a 4 node setup. My current plan is a 4 node cluster using Storage Spaces Direct with 3 tiers of storage and all I have left to purchase is a few 4TB drives and 6 NVMe SSD’s.
I find that I am constantly learning while reading through these forums and sometimes I learn that I spent my money unwisely. So, what I am hoping for is some feedback, especially with regards to the parts I have not ordered yet. The servers host VM’s and provide storage for my workstations and for the kids gaming machines. We have a QDR Infiniband network setup (that I put together almost entirely from info on this forum).
For this build I have, or is in transit:
04 x SuperMicro 2U 12 Bay (6027R-E1R12N) w/ E5-2670’s
12 x SAMSUNG SM843T 2.5" 480GB SATA 6.0Gb/s MLC Enterprise SSD
14 x 4TB HDD
02 x 256GB MyDigitalSSD NVMe w/PCIe cards
What I still need to purchase:
06 x M.2 NVMe ~250GB SSD’s and PCIe brackets
02 x 4TB HDD
I want to use the NVMe drives as cache, the SSD’s as Hot Storage and the HDD’s as Cold Storage. I believe that using dual parity with storage spaces direct my setup should be able to withstand 2 node failure. Of course storage efficiency isn’t that great with this setup. For the VM’s I will likely just use the SSD’s and deduplication.
Currently unallocated I have:
04 x 500GB 840/850 Evo’s
10 x 3TB HGST Ultrastar HDD’s
04 x 3TB WD RED’s
01 x 4U SuperMicro 45 Bay 3.5” SAS2
08 x 2TB various HDD’s
02 x Intel RES2CV360
I wanted to use the 3TB drives to provide more space but from what I understand it would limit the 4TB drives to only 3TB usable because the columns would spread out evenly.
Are there good used NVMe drives to be had on ebay? The MyDigital ones that I have use MLC and the speeds are ok and they are pretty consistent. I have a hate on for the current crop SSD’s that use a cache and advertise the cache speed as if it’s a steady state speed. How is this any different than the RAM on a HDD? I am looking to spend about $120 each and I need 6 or 8 of them. Speed is the highest priority and then capacity. I actually have 2 SM961’s, I like them but they are a bit too pricey for me to get another 6.
