Replacing HHHL Form-Factor NVMe Solid State Drives
This section is for replacing half-height, half-length (HHHL) form-factor NVMe SSDs in the PCIe risers.
HHHL SSD Population Guidelines
Observe the following population guidelines when installing HHHL form-factor NVMe SSDs:
• Two-CPU systems—You can populate up to 6 HHHL form-factor SSDs, using PCIe slots 1 – 6.
• One-CPU systems—In a single-CPU system, PCIe riser 2 is not available. Therefore, the maximum
number of HHHL form-factor SSDs you can populate is 3, using PCIe slots 1 - 3.
HHHL Form-Factor NVME SSD Requirements and Restrictions
Observe these requirements:
•
All versions of the server support HHHL form-factor NVMe SSDs.
Observe these restrictions:
•
You cannot boot from an HHHL form-factor NVMe SSD.
•
You cannot control HHHL NVMe SSDs with a SAS RAID controller because NVMe SSDs interface
with the server via the PCIe bus.
•
You can combine NVMe SFF 2.5- or 3.5-inch SSDs and HHHL form-factor SSDs in the same system,
but the same partner brand must be used. For example, two Intel NVMe SFF 2.5-inch SSDs and two
HGST HHHL form-factor SSDs is an invalid configuration. A valid configuration is two HGST NVMe
SFF 2.5-inch SSDs and two HGST HHHL form-factor SSDs.
Replacing an HHHL Form-Factor NVMe SSD
In a single-CPU server, PCIe riser 2 (PCIe slot 2) is not available.Note
Step 1
Remove an existing HHHL form-factor NVME SSD (or a blank filler panel) from the PCIe riser:
a) Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server,
on page 39.
