Supercap Power Modules (RAID Backup Units)

Supercap Power Modules (RAID Backup Units)

T

his server 

supports installation of two supercap power module (SCPM) backup units. The units mount 

to trays on the removable air baffle (see 

Replacing the Supercap Power Module (RAID Backup Unit), 

page 3-53

).

The SCPM is available only when using the LSI MegaRAID-CV controller cards. This module provides 
approximately 3 years of backup for the disk write-back cache DRAM in the case of sudden power loss 
by offloading the cache to the NAND flash.

Mixing Drive Types in RAID Groups

Table C-2

 lists the technical capabilities for mixing hard disk drive (HDD) and solid state drive (SSD) 

types in a RAID group. However, see the best practices recommendations that follow for the best 
performance.

Best Practices For Mixing Drive Types in RAID Groups

For the best performance, follow these guidelines:

  •

Use either all SAS or all SATA drives in a RAID group.

  •

Use the same capacity for each drive in the RAID group.

  •

Never mix HDDs and SSDs in the same RAID group.

RAID Controller Cabling

The maximum two supported RAID controller cards should be populated in PCIe slots in the following 
order (see 

Figure 3-23 on page 3-43

): 

1.

PCIe slot 3

2.

PCIe slot 5

Refer to the following examples for cable routing guidelines: 

  •

Example 1—One Nonexpander and One RAID Controller with Eight Drives, page C-3

  •

Example 2—Two Nonexpanders and Two RAID Controllers with 16 Drives, page C-4

  •

Example 3—Two Expanders and One RAID Controller with Sixteen Drives, page C-5

For more information about transition cards, see 

Replacing a Modular Drive Bay Assembly, page 3-14
