12 Storage
12.1 Overview
The Dell™ PowerEdge™ R910 system supports up to sixteen 2.5” hard disk drives. See Table 11 for
details.
12.2 Backplanes
R910 supports either a sixteen-drive backplane or a four-drive backplane for 2.5” drives.
Depending on the type of backplane, there are sixteen or four hot-plug capable Serial Attached SCSI
(SAS) or Serial ATA (SATA) drive slots with two LED indicators per slot, up to two Mini-SAS cable
connectors for connecting the backplane to the integrated PERC H200 or H700 storage adapters, and
a 20-pin planar signal/power connector. PERC H200 storage adapter will only be supported with the
2.5” 4-drive HDD backplane.
12.2.1 2.5” x4 Backplane
The four-drive 2.5” backplane assembly is detailed as follows:
 Only 2.5” drives are supported in this configuration
 One mini-SAS cable is used to connect channel “A” of the integrated PERC H200 or H700
storage controller card to the four-drive backplane.
 Mixing SATA and SAS is not supported.
12.2.2 2.5” x16 Backplane
The sixteen-drive 2.5” backplane assembly is detailed as follows:
 Only 2.5” drives are supported in this configuration
 Two mini-SAS cables are used to connect both channels of the integrated PERC H700 storage
card to the sixteen-drive backplane.
 A SAS expander is used to map 16 drives to the PERC H700 (2 x4 SAS) controller
 Mixing SATA and SAS is not supported.
 Mixing SAS and SSD is supported.
12.3 Flash BIOS Memory
A Flash EEPROM resides on the SPI Bus for BIOS and configuration storage. A 16 Mbit device is utilized
for this function. The Flash memory permits the BIOS to be upgraded in the field. The Flash BIOS may
be write-protected by software.
12.4 Drives
The PowerEdge R910 supports the new 2.5” hard drive carriers. These carriers implement new
industrial design to match the front bezel.
For the slots that are not occupied by drives, a carrier blank is provided to maintain proper cooling,
maintain a uniform appearance to the unit, and provide EMI shielding.
R910 supports diskless configuration.
