Note: Short Wave Cable Grade and Speeds correspond to four types of Maximum Distance by Optical Cable/Media.
Direct Attach Copper
All model arrays also support SFP+ Direct Attach, also known as 10GSFP+Cu. This IEEE Standard network topology uses
10Gb Ethernet over twinaxial copper cables that plug directly into SFP sockets. No transceivers are used.
Direct Attach twinaxial can be designed as "Active" or "Passive" cables, and can have a maximum link distance of about 10
meters (33 feet). HPE storage arrays support Passive Direct Attach twinaxial cables of the appropriate length. Active Direct
Attach twinaxial cables are not currently supported.
Note: HPE does not supply 10GSFP+Cu cables.
Statement of Volatility
Below are the identifications of volatile and non-volatile devices found in the HPE Alletra 6000 storage arrays. For PCIe or
OCP cards, refer to vendor information.
