Questions & Answers
What is the HPE XL230k M.2 Enablement Kit (SKU: 866317-B21)?
The HPE XL230k M.2 Enablement Kit (866317-B21) is an accessory that adds two M.2 2280 drive slots to HPE XL230k Gen10 servers, enabling direct-attached SSD storage for operating systems or applications.
Which HPE servers are compatible with this enablement kit?
This kit is verified for HPE XL230k Gen10 servers; compatibility requires system firmware version 2.30 or later. It is not supported on other server models.
How many M.2 drives can I install with this kit?
The kit supports up to two M.2 2280 SSDs, each connected via a dedicated PCIe or SATA interface, depending on your SSD choice.
Which M.2 form factors and interfaces are supported?
It supports 2280 form-factor M.2 SSDs in both NVMe (PCIe Gen3 x4) and SATA III modes, providing flexible performance options.
Can I use these M.2 drives for the boot volume?
Yes. The enablement kit supports hosting the server’s operating system and boot partitions on the installed M.2 SSDs for faster startup and reduced latency.
Are the M.2 SSDs included with the kit?
No. The kit includes the mounting bracket, cabling, and connectors only. M.2 SSDs must be purchased separately.
