DRIVES
The VSS2249RQ Storage Server supports 24 U.2 (SFF8639) NVMe SSDs.
Drives may be dual or single ported; however, single ported drives report only to
Server Module 1 (on the left as viewed from the enclosure rear). Drives are
hot-swappable. Drive replacement is a cold aisle service action. Shutting down
the system to replace a drive is not necessary; however, verify no data
transactions are taking place before hot-swapping any of the NVMe drives.
Drive Mapping and Zoning Review
Drives are mapped according to their location within the enclosure. Each drive is
numbered from 1 through 24. While facing the front of the enclosure, numbering
begins with Drive 1 in the first slot on the left, and then increases incrementally
from left to right.
Drive Carrier Assemblies
A drive carrier assembly is comprised of the drive or drive blank and a drive
carrier, and are utilized to provide for controlled insertion into, and extraction
from, the storage enclosure. Drive carrier assemblies are installed via the front
of the enclosure, which simplifies service access. Closing the drive carrier
handle ensures complete seating of the connectors through typical operational
shock and vibration.
All 24 drive bays must be filled with drive carrier assemblies—each containing
either a drive or drive blank—to ensure proper airflow and system cooling.
Figure 8.12 provides a close-up view of a drive carrier assembly with a
preinstalled NVMe SSD.
