Replacing a 2.5-Inch Form-Factor NVMe PCIe Solid State Drive
This section is for replacing 2.5-inch small form-factor (SFF) NVMe PCIe SSDs in front-panel drive
bays. To replace HHHL form-factor NVMe PCIe SSDs in the PCIe slots, see Replacing HHHL Form
Factor NVME Solid State Drives, page 3-21.

2.5-Inch Form-Factor NVMe PCIe SSD Population Guidelines
The SFF 8-drive version of the server supports up to two NVMe SFF 2.5-inch SSDs in drive bays 1 and
2 only.
2.5-inch Form-Factor NVME PCIe SSD Requirements and Restrictions
Observe these requirements for NVMe SFF 2.5-inch SSDs:
• Only the SFF, 8-drives version of the server supports NVMe SFF 2.5-inch SSDs.
• The server must have two CPUs. PCIe riser 2 is not available in a single-CPU system (the PCIe riser
carries the PCIe signal from the front panel drive bays).
• PCIe riser version 2B (UCSC-PCI-2B-220M4), with bundled cables. This version of the riser has
cable connectors for the PCIe cables that connect to the drive backplane.
Observe these restrictions for NVMe SFF 2.5-inch SSDs:
• You can boot (UEFI only) from an NVMe SFF 2.5-inch SSD only with Cisco IMC 2.0(13) or later
server firmware. For Cisco UCS Manager-integrated servers, booting is supported only with Cisco
UCS Manager 3.1(2) or later software.
• NVMe SFF 2.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported.
• You cannot control NVMe PCIe SSDs with a SAS RAID controller because they communicate with
the server via the PCIe bus.
• You can combine NVMe SFF 2.5-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
HHHL form-factor HGST SSDs is an invalid configuration. A valid configuration is two HGST
NVMe SFF 2.5-inch SSDs and two HGST HHHL form-factor SSDs.
• UEFI boot is supported in the five operating systems listed in Table 3-4, when your server is running
Cisco IMC 2.0(13) or later firmware. Refer to this table for OS-informed hot-insertion and
hot-removal support by operating system:
