The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Dedicated socket that can be used to add an mLOM card for additional rear-panel connectivity. |
|
1-Gb BASE-T Ethernet LAN ports support the wake-on-LAN (WoL) standard. |
|
Two AC power supplies: 770 W AC each. Redundant as 1+1. See Power Specifications. |
|
The advanced configuration and power interface (ACPI) 4.0 standard is supported. |
|
Two horizontal PCIe4 expansion slots (single riser assembly). |
|
The bus slots in this node support the InfiniBand architecture. |
|
Drives are installed into front-panel drive bays:
– HX220c: Up to six HDD persistent data drives in bays 3–8. – HX220c All-Flash: Up to six SSD persistent data drives in bays 3–8. See Cisco HX220c All-Flash HyperFlex Nodes Overview for more information. |
|
One internal USB 3.0 port on the motherboard that you can use with a USB thumb drive for additional storage. |
|
The node has a dedicated internal riser for a PCIe-style Cisco modular HBA card. For a list of controller options and required cabling, see Supported HBAs and Required Cables. |
|
VGA video resolution up to 1920 x 1200, 16 bpp at 60 Hz, and up to 256 MB of video memory. |
|
The HX220c All-Flash HyperFlex node contains all SSDs, rather than the hybrid mix of SSDs and HDDs that is used in the HX220c HyperFlex node. Enterprise value SSDs are used for the persistent data drives. Enterprise high-endurance SSDs are used for the caching drives.
Note the following considerations and restrictions:
See HX220c Drive Configuration Comparison for specifics about drive PIDs supported in the node types.
