Sandisk SX350-1600 for Ceph any good?

[silbro]

Hi

Has anyone tried the Sandisk SX350-1600 PCI-E for CEPH?

If yes, is it any good? (Maybe you can provide some benchmarks if you have any)

Thanks in advance!

I would recommend some enterprise SSDs from Samsung. Do not buy cheap SSDs, that's normally only crap for CEPH. Put in some more money and you will save this later.

If i'm not mistaking, you're talking about Sandisk IoMemory. They should be crazy fast.
I use the previous generation of Fusion-Io and i get 1-1.5GBps RW and around 200k IOPS.
So it should be very good.

@sb-jw I thought these Sandisks were enterprise https://www.sandisk.com/content/dam...0-pcie-application-accelerators-datasheet.pdf

@Vladimir Bulgaru Yes I'm talking about the Sandisk IoMemory. So you use the previous ones for Ceph or just as disks?

@silbro I use it for VMs. Work like a charm. Haven't tried Ceph yet, though. But i'm sure they can manage.
