Purchased this PCIe SSD for a PowerEdge R740xd running ESXI 6.0 expecting to see the 500k IOPS advertised:
This is being allocated to two RHEL7 VMs.
However, when running fio and ioping I can see that the IOPS only reach around 120k for random read/writes.
This slower than expected speed first became apparent when the database used on the server did not perform any better using this SSD than it did on 15K HDDs.
I've been talking with our vendor about this but they are not sure what the issue is.
Digging around on VMware's site I find this:
Is this the install that's needed to get these PCIe to function as advertised?
Has anyone else here seen this issue with these PCIe SSDs?
Will installing this have any negative effect on the hard disks already in use by the server?
