Hard drives
Your system supports entry hard drives and enterprise class hard drives. Entry hard drives are designed for 5x8 operating environment
with less workload rating to drives, and enterprise class drives are designed for 24x7 operating environment. Selecting the correct drive
class enables optimization of the critical areas of quality, functionality, performance, and reliability for the target implementation.
NOTE:
Do not mix enterprise class drives with entry hard drives.
Choosing the right drive type depends on the usage pattern. Improper use of entry hard drives (workload rating that exceeds 55 TB/year)
leads to significant risk and increases the failure rate of the drives.
For more information about these hard drives, see the 512e and 4Kn Disk Formats white paper and 4K Sector HDD FAQ document at
Dell.com/poweredgemanuals.
CAUTION:
Before removing or installing a hot swappable hard drive, read the storage controller card documentation to
ensure that the host adapter is configured to support hot swappable hard drive removal and installation.
CAUTION: Do not turn off or restart your system while the hard drive is being formatted. Doing so can cause a hard
drive failure.
Use only hard drives that have been tested and approved for use with the hard drive backplane.
When you format a hard drive, allow enough time for the formatting to be completed. Be aware that high-capacity hard drives can take
several hours to format.
Supported hard drive configurations
Depending on the configuration, your system supports one of the following:
Two hard drive
systems
Up to two 3.5-inch cabled hard drives
Four hard drive
systems
Up to four 3.5-inch hot swappable SATA hard drives, or SATA solid state drives
Up to four 3.5-inch cabled hard drives
Up to four 2.5-inch hot swappable hard drives with 3.5-inch hard drive adapters
NOTE: SAS/SATA hard drives cannot be mixed in a system.
The hot swappable hard drives connect to the system board through the hard drive backplane. Hot swappable hard drives are supplied in
hot swappable hard drive carriers that fit in the hard drive slots.
