Hot-swappable hard drives

Your system supports Entry Hard Drives and Enterprise Class Hard Drives. Entry Hard Drives are designed for 8x5 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.
Do not mix Enterprise Class Drives with Entry Hard Drives.
NOTE:
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.
Choosing the right drive type depends on the usage pattern. Improper use of Entry Hard Drives (workload rating exceed 55TB/
year) will lead to significant risk and increase the drives failure rate.
All hard drives connect 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 completed. Be aware that high-capacity hard drives
can take a number of hours to format.
