Hard Drives; Removing A 2.5 Inch Hard Drive Blank (Rear) - Dell E31S Series Owner's Manual

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 will enable the critical areas of quality, functionality, performance, and reliability to be optimized for the target implementation.
NOTE: Do not mix enterprise-class hard drives with entry hard drives.
Choosing the right drive type depends on the usage pattern. Improper use of entry hard drives (workload rating exceeds 55TB/year) will
lead to significant risk and increase the drives failure rate.
For more information on these hard drives, see the 512e and 4Kn Disk Formats whitepaper and 4K Sector HDD FAQ document at
Dell.com/poweredgemanuals.
All hard drives are connected to the system board through the hard drive backplane. Hard drives are supplied in hot-swappable hard drive
carriers that fit in the hard drive slots.
CAUTION: Before attempting to remove or install a hard drive while the system is running, see the documentation for
the storage controller card to ensure that the host adapter is configured correctly to support hot-swap hard drive
removal and insertion.
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 complete. Be aware that high-capacity hard drives can take a
long time to format.
