anyraid 720ix, crippled write performance , ssd raid level 10

2019-10-10, 12:37 PM

hi all,

 

we are experiencing a bottleneck in write performance concerning

the ssds connected to the anyraid 720ix. we are using 4

samsung SSD850 on raid level 10. the maximum write performance

is 50MB/s. that is far to slow compared to the HDDs wich come

up to 300Mb/s onRAID level 5. we are unsure of the cause of this.

 

system is:

  thinkserver rd650 , win2k12r2, 64Gb

  megaraid store manager v17.05.01.02

  bios PB2TS443

 

is it possible that the standard ssds are not supported?

can it be a licensing problem of the megaraid store manager?

any hints welcome.

 

thank you very much for your help.

Do the samsung SSD850 have a Lenovo Part number on them?

Also one additonal thing I thought of is are you using a cache upgrade for the 720ix AnyRAID adapter? If so which one?

RAID FW version will impact the IO performance, which RAID FW version is for 720ix? the latest version is 24.21.0-0097,

http://driverdl.lenovo.com.cn/lenovo/DriverFilesUploadFloder/server/2019071714545222800/fw_avago_hwr_sas3_24.21.0-0097.zip 

Suggest to  upgrade latest 720ix RAID FW, and upgrade latest driver version in the same time.

thank you for your thoughts.

sorry no lenovo part number - they are "off the shelf" samsung ssds, 500GB each.

the firmware version is older - we will try the upgrade. to version 24.21.0-0097.

thank you for your replies.

sorry i am not sure how to find out about the cache upgrade. we installed a cachecade but deactivated

it as it did not improve the situation.

 

here is what the megaraid management software says:

HARDWARE---             
 Controller:              Controller0: Lenovo ThinkServer RAID 720ix AnyRAID Adapter(Bus 4,Dev 0,Domain 0)
 Status:                  Optimal

 Firmware Version:        4.680.00-8434
 BBU:                     YES
 Enclosure(s):            1
 Drive(s):                13
 Virtual Drive(s):        3
