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 the critical areas of quality, functionality, performance, and reliability to be optimized 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 exceed 55 TB/year) leads
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

Limitations for SATA SSDs backplane configurations:
•
Four hard drive systems: No limitations
•
x24 hard drive systems with unified backplane (single-PERC configuration): SATA SSDs might be installed in slots 12-23 only.
•
x24 hard drive systems with Dual-PERC (performance) configuration: No limitations

x16+8 PCIE systems: SATA SSDs might only be installed in slots 8-15.
NOTE:
SSD/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.
