Poor write speed of Kingston DC400 SSD on G7 Server

Hello,

I am using Kingston SEDC400S37/960G Enterprise SATA SSD on HP DL 380 G7 server.

Its giving me gud read performance but the write performance is very poor. 

SEQ         Read - 247.96 MB/s   Write - 82.21 MB/s

4K           Read- 15.40 MB/s      Write - 1.63 MB/s

Acc.Time  Read - 0.302 ms        Write - 2.431 ms

I have P410i Raid controller and firmware/drivers are updated.

SSD Firmaware is also updated.

Have you solved this issue ?  Because I have DL380e Gen8 with P420/1GB FBWC, 2x Xeon E5-2450L, 128GB of RAM, DC400 960 GB in RAID-1 and my server is also horribly slow ! :o

Hello,


I think is the same problem i get with samsung 840 pro.

You need to enable the disk cache write. The DC400 have a lot of features is made by the firmware (like dataprotection is soft and not by capacitor).

did you try to send a support request to Kingston too ?

 

Did you try to configure the controller cache to 100% read or  100% write ? Or simply Disabled ?

Best Regards
