IOPS for SSD?

@Pete-S said in IOPS for SSD?:
I'm interest in this myself as I have a customer that are looking at ESXi on Dell R740 servers with the same type of CPU that you have but with less storage capacity overall.
I just looked at the cost. You have to select a different chassis- "Chassis up to 24 x 2.5 Hard Drives including 24 NVME Drives, Max of 8 SAS/SATA" , which adds about $1300 bucks,
However, the 960GB nvme drive is only about $50 more than the 960 GB 12Gbps SAS drive I was looking at.The problem for me, is that I can't get the storage density I need when using 2.5" drives. Also, it would cost quite a bit more if I could.

Interesting. I suppose the question is - do you need the IOPs of NVMe? If so - then perhaps an external DAS shelf for the 3.5 drives for the fileserver would be the way to go.
Of course, if you're using something like StarWinds to create a vSAN for shared storage, that really ups the cost a lot (doubling everything and all).

Since NVMe drives has the best performance and NVMe driver technology is superior, it makes sense to pick NVMe whenever you can. NVMe drives and the SAS-3 drives are priced roughly the same so you get the extra performance for free (if the chassis can take NVMe).
NVMe drives are directly attached to the PCIe bus on the CPU and that why Intel for instance refer to SATA/SAS as legacy technology. The PCIe bus interface is also the reason why they are faster.

Of course - but @wrx7m said the chassis is $1300 more expensive, assuming the backplane for NVMe can't take SATA/SAS SSDs, and is limited to NVMe, that means he can't use less expensive drives for fileshares - which then causes him to need a DAS to host those drives (@wrx7m already mentioned that the size/slot limitations of the NVMe chassis prevented him from having enough storage for File server). So that's even more expense than just the $1300.
Plus @wrx7m is doubling everything up, so the costs just keep on climbing.

Yes, you're right. NVMe is not a good fit in this case. Even if it's more limitation by Dell than anything else.

Yes, you're right. NVMe is not a good fit in this case. Even if it's more limitation by Dell than anything else.
Also looks like you can use NVMe drives on 740xd for a $470 premium, not $1300.
But Dell have limitations how you can configure so it's possible that something else will become more expensive instead.
In the case of @wrx7m it won't work since he needs 3.5" drives but it might for others.

@Pete-S They dropped the price to 1061.24 since I posted. lol Interesting. Yes, but that is a max of 12 nvme. I may have misunderstood that option with 8 SAS/SATA. I am guessing that the max of 12 would allow for more SAS/SATA, although it doesn't mention it. My issue was also with the available drive capacities and cost per TB for spinning disks in the 2.5" spec.

Yeah, especially direct from the OEM. Have you thought about buying the storage from xByte instead?

Are their drives brand new? I did price out a server with specs as similar to Dell's as possible and it was only off by a couple grand.

Ah, I was thinking the price difference would be bigger.

IMHO, I consider their drives are 99.9% brand new as its possible an OEM install was done on the drive or something like that. Plus testing of the drive by the OEM and xByte.
Their hardware is manufacturer refurbished, not used. Big difference.
If you can get a Dell ProSupport (w/w-out) Plus 7 year warranty on the server with the drives from xByte, it doesn't really matter if they are new or not. They are under warranty for 7 years and you have no worries.
