Dell has recently announced new features and options in the XC Nutanix lineup to get the year started. The Dell/Nutanix relationship is still going strong with a bunch of announcements in December 2015 and with the release of NOS 4.6 due at the end of January there are even more improvements.

December 2015 Announcements

  • Improved SSD options
  • XC630-10F All-Flash node
  • XC 6320-gF All-flash node (4 node in 2RU)
  • Dell SAS HBA330 on all new models except XC6320(12G SAS)
  • 6TB drive support on XC730 & XC430
  • 64GB DIMM support

January 2016 Announcements

  • 40TB Capacity Nodes (previously 32TB)
  • MS SCOM Management Dell Agent Free Pack*
  • SED support on SSD & NLSAS across all models

* Documentation to be released shortly

Two useful Reference Architectures for Dell XC have been released as well. They explain how to set up a 3-node XC630 cluster and cover network setup, (cabling, switch configurations, and VLAN tagging) initial cluster creation and best practices.

Acropolis (AHV) Reference is in the works but not for a little while.

With the NOS 4.6 code about to be released it allows support for 40TB per node on the XC730 series.


Up to 12 x 3.5″ drives. SSD support is Min 2 – Max 4 with sizes of 200/ 400/ 800/ 1600GB. For the HDD there is a Min 4 – Max 10 with 2/ 4/ 6TB options.


Up to 24 x 2.5″ drives. SSD support is Min 2 – Max 4 with sizes of 200/ 400/ 800GB. For the HDD it’s Min 4 – Max 20 drives with 1/2/TB options.xc730-24


Up to 12 x 3.5″ drives. This is the Lite Compute Storage Node. It has 40TB Fixed Capacity with  2 x 400GB SSD and 10x4TB HDD.XC730xd

For the All-Flash nodes currently all drive slots need to be populated but that restriction should be lifted in the coming months.

If you were to fill the XC630-10F with 1.6TB SSD drives you would have 16TB RAW per node BEFORE dedupe and compression in 1RU. Very cool. At the moment it is best practice to create a seperate cluster for All-flash nodes.

Lots of information in the XC630 owners manual.

There is a lot of interest around Nutanix and Dell Networking at the moment, especially around Software Defined Networking and linux based solutions such as Cumulus. The Open Networking (ON) range lets customers load the networking OS of choice on their switch, Cumulus, BigSwitch or Dell FTOS to name a few. There is a load of information on the Dell Networking for Nutanix wiki.

The Dell Storage wiki for XC Series has loads of information about XC solutions and models if you need to go deeper. If there are any questions please let me know in the comments below of on twitter @danmoz
