Hello All
We are refreshing the hardware for our main DB and I'm moving it to new DL380 G10 with 4 x 10GBps interfaces connected to four 10GBps ports - two ports on each of the two controllers of the MSA 2052 via HPE FlexFabric 5700 40XG 2QSFP+ Switch.
I have 9 800SSDs disk and 11 SAS 1.8TB. 8 of SSDs in raid 10 one spare and 10 SAS in raid 10 and 1 spare. They are part of one pool for Performance and Archive tire. I know it recommended to have it balanced on more pools but I need all the disk space accessible on this single server for the DBs
I have two LUNs - one with Performance affinity and one with Archive presented to the server.
I installed Windows 2012R2 on USB connected Kingstone 240 SSD to test the performance and use ATTO to asses it with 8K I/O size(this is the block our DB uses).
Installed al the latest firmware and drivers on from Gen10 SPP enabled multipath.
On both LUNs I get only 4.5k to 6.8k IO/s.
If I run it against the USB SSD I have theOS on I get more than 20k IO/s reads and rights
I would expect this storage with this type of drives and this configuration to give a lot more performance than the €100 USB SSD drive.
Most probably I'm doing something wrong so I will appreciate any advise on how to improve the performance.
