Goal

Provide guidelines for installing mixed drive types within the 24 SFF disk backplane (SPARC S7-2L only)

The 24 SFF (Small Form Factor) Drive Cage configurations include 2 Rear SFF Disks for a total of 26 disks

• Disks of larger capacity are more likely intended for data storage as opposed to the Operating System (OS)
  • Use smaller HDDs as OS disks, but generally do not use the SAS SSDs as OS disks
• SAS SSDs are likely intended for high-performance caching operations, and so should not be used for OS installation
• SAS HDDs and SAS SSDs may be installed in all 26 disk bays
  • SFF SAS HDDs and SSDs may also be installed in the 2 rear disk bays (Rear HDD0 and HDD1)
• NVMe Disks are required to be installed in HDD3, HDD4, HDD19, HDD20 (aka. NVMe bay 0-3)

Solution

Configuration Rules (SPARC S7-2L only)

Sort disks by capacity and technology (HDD, SSD, NVMe). Install all supplied cables.

Install drives in this order:
1. NVMe’s first, starting with front-mounted available storage bays HDD3, HDD4, HDD19, & HDD20 (aka. NVMe bay 0-3) in ascending HDD bay number 3, 4, 19, & 20
2. HDDs next, starting with the smallest capacity, starting with the front-mounted available storage bays in ascending HDD bay number (0, 1, etc.), skipping over any bays populated by NVMe drives. Install larger capacity HDDs in increasing capacity and into storage bays increasing in HDD bay number.
3. Install SAS SSDs into the remaining available storage bays increasing in HDD bay number.
4. Install SFF SAS HDDs into rear bay numbers (Rear HDD0 and HDD1)
5. Install SFF SAS SSDs into the remaining available rear bay numbers (Rear HDD0 and HDD1) increasing in number.
6. Drive slots not populated with a Drive must be populated with a Marlin Filler.
