IBM x3650 M5 - Upgrade ServeRAID M5210 to Support RAID5 and still co-existence with current RAID1 DG

2020-04-24, 16:35 PM

I have Centos 7 running on IBM x3650M5, currently configured with 1 DataGroup :  2x1TB SAS Hardisk (RAID1 configuration) using ServeRAID 5210.

 

I would like to add a 2nd DataGroup, consist of 4x2TB SATA Hardisk (RAID5 Configuration) sharing the current ServeRAID 5210 Controller.

 

I read through the X3650 M5 hardware manual, in order to support RAID5, I need to do optional upgrade the current ServeRAID controller, like eg upgarde to RAID 5/50 (4GB Flash)

 

Since, I never done this before, I need some advice of what is required and how to do it.

 

I have some questions below probably someone can help me answer:

 

  1. Could I use 1x ServeRAID 5210 controller to support DataGroup 1 (RAID1) and DataGroup 2 (RAID5) simultaneously?
  2. What Optional Upgrade do I need to choose to achieve what I intend to do in question #1 (ie. add a 2nd DataGroup RAID5)?
  3. Could I mix 2.5" SAS Hardisks (RAID1) & 2.5" SATA Hardisks (RAID5)  in my current Hardisk Drive Bays??

 

Thank you

Hi Benindo

 

According to ServeRAID M5210 and M5210e SAS/SATA Controllers Product Guide section Feature upgrade matrix, the ServeRAID M5210 and M5210e provide support for RAID 0, 1, and 10 as standard capabilities. Additional optional functional upgrades are available to expand the standard capabilities. You can refer the table to select upgrade feature to support RAID5.

Please refer the answer for your question as below.

1. The ServeRAID M5210 SAS/SATA controller support for up to 64 virtual disks, up to 128 arrays, up to 16 virtual disks per array, and up to 32 physical drives per array. So you can create two data group simultaneously.

2. You can refer to the upgrade matrix and base on your requirement to select part for upgrade.

3. According to Controller Guidelines in the ServeRAID M5210 user guide as below.  

  • You cannot mix SAS drives and SATA drives in the same virtual drive
  • You cannot mix SAS Solid State Drives (SSDs) or SATA SSDs and existing mechanical drives (SAS or SATA) in the same virtual drive
  • You cannot mix Solid State SAS drives and Solid State SATA drives in the same virtual drive
