Details
A HX220c node has 8 front-mounted SFF disk slots; In the M4 series 2 disk slots are reserved for SSDs. This effectively means that each node can have up to 6 HDDs installed; M5 series can have up to 8 HDDs installed. Initial configurations have 6 to 8 HDDs installed; exception is the Edge bundle where 3 to 6 HDDs can be installed.

A HX240c SFF node has 24 front-mounted SFF disk slots; 1 disk slot is reserved for SSD. This effectively means that each node can have up to 23 HDDs installed. Initial bundle configurations have either 11 or 15 HDDs installed. Custom configurations have 6 to 23 HDDs installed. In addition a HX240c M5 SFF node has 2 rear SFF disk slots.

A HX240c LFF node has 12 front-mounted LFF disk slots. This effectively means that each node can have up to 12 high-capacity HDDs installed. Initial bundle configurations have either 6 or 12 HDDs installed. Custom configurations have 6 to 12 HDDs installed. In addition a HX240c M5 LFF node has 2 rear SFF disk slots. 1 rear SFF disk slot is reserved for SSD.

A HXAF220c/HXAN220c node has 8 front-mounted SFF disk slots; In the M4 series 2 disk slots are reserved for non-data SSDs. This effectively means that each node can have up to 6 data SSDs installed; M5 series can have up to 8 data SSDs installed. Initial configurations have 6 to 8 SSDs installed.

A HXAF240c node has 24 front-mounted SFF disk slots; 1 is reserved for a non-data SSD. In addition a HXAF240c M5 node has 2 rear SFF disk slots for non-data SSDs. This effectively means that each node could have up to 23 data SSDs installed. However, in M4 systems only up to 10 3.8TB data SSDs can be configured.


HX 3.0 added support for a second NIC in HX nodes on a RPQ basis. HX 3.5 supports this unconditionally and the second NIC is now a part of the HX installer and deployment is automated.
