Dear All

We are starting implementation of SAP B1 on HANA 9.2 at a Customer's. Our customer is in the process of sourcing the hardware and OS separately, since HANA appliance is not available in our country. The server will be a DELL R630/T630 with 128 GM RAM. I was looking into the exact BOM from this location ( The BOM mentions the following for the storage:

RAID Configuration: RAID 5 for H330/H730/H730P (3-24 HDDs or SSDs)
RAID Controller: PERC H730 Integrated RAID Controller, 1GB NV Cache, Full Height
Hard Drives: 600GB 10K RPM SAS 6Gbps 2.5in Hot-plug Hard Drive (choose Qty 4 for 64,96,128,256 GB RAM, choose Qty 6 for 384 and 512GB RAM)

It appears they are recommending 4 disks for 128 GM RAM.

The guideline (How to Configure Hardware Platforms for SUSE Linux Enterprise Server.pdf) on Server configuration given in Note: 1944415 ( mentions the following from Page-17 onwards for DELL PowerEdge R630/T630:

Depending on the main memory, these models can have the following configuration:
- 7 disks (for the operating system, the SAP HANA data, and the SAP HANA log) as RAID5 and 1 disk as a hot spare
- 4 disks as RAID5 (no hot spare)
- 6 disks as RAID5 (no hot spare)

We have couple of questions now:
1. Our Customer is asking if there is any specific reason why 10K disks are being used instead of 15K since the disk sizes are quite large (600GB). Is using 15K disks an option or should we stick to 10K for ensuring exact HANA compatibility?

2. The server configuration guideline mentions not requiring any Hot Spare disks for 4 disk setup. In that case, what will be the final configuration? Is the following correct?
- 1 Disk Group (Disk Group 0)
- 2 Virtual Drives (Virtual Drive 0, Virtual Drive 1)
- Virtual Drive 0: Size = 53 GB
- Virtual Drive 1: Size = as per system recommendation)

Thanks in advance.

Hi Shougata:

Have you solved your question? I'm on a similar issue I have a Dell R730 with SSD, as the documentation I need - 3 drives as RAID5 (no hot spare) as I have 128GB, my question is: my server came with 7 400GB SSD, what should I do with the other 4 SSD?

Thank you.
