Introducing Cisco UCS S-Series

Today Cisco announced the Cisco UCS S Series line of storage servers.

S-Series-fronts-series-logoNow the more eagle eyed among you may think that the new Cisco UCS S3260 Storage Server looks very much like the Cisco UCS C3260 Rack server (Colusa), well you wouldn’t be too far off, however the S3260 has been well and truly “Pimped” to address the changing needs of a modern storage solution, particularly an extremely cost effective building block in a Hybrid Cloud environment.

The C-3160/C-3260 was particularly suited to large cost effective cooler storage solutions, that is to say the retention of less / inactive data on a long-term or indefinite basis at low cost, use cases being, archive or video surveillance etc.. The fact is data is getting bigger and warmer all time time and it shows no signs of slowing down anytime soon. And even on these traditional colder storage solutions the requirement for real time analytics on this data is requiring an ever increasing amount of compute coupled with this storage.

So Cisco have created this next generation of Storage Server to meet these evolving needs.

If there is a single word to describe the new Cisco UCS S-Series it is “Flexibility” as it can be configured for:

Any Performance, Right sized to any workload
Any Capacity, Scale to Petabytes in minutes
Any Storage: Disk, SSD or NVMe
Any Connectivity. Unified I/O and Native Fiber Channel

Highlights

  • Fully UCS Manager Integrated

Since UCS Manager 3.1  (Grenada) all Cisco UCS products are supported under a single code release, including the S-Series storage servers (UCSM 3.1.2)

  • Modular Components to allow independent scaling.

As we know different components generally have different development cycles, the S-Series storage servers  are built with a modular architecture to allow components be upgraded independently, for example, as and when the 100Gbps I/O module is released it’s a simple I/O module replacement, similarly when the Intel Skylake Purley platform (E2600 v5) is available it’s just a server module upgrade.

  • Up to 600TB in a 4U Chassis, then scales out beyond that in additional 4U Chassis
  • 90TB SSD Flash

As can be seen below the Cisco UCS S3260 can house up to 2 x Dual Socket M3 or M4 Server nodes, but you also have options of using a single server node then adding either an additional Disk Expansion module , or an additional I/O Expansion module.

Server Node Options.

Server-Nodes

 

System I/O Controller

The 2 Fabric (SIOC)  modules map to each of the server nodes, i.e Fabric Module 1 to Server Node 1 and Fabric Module 2 to Server Node 2. This provides up to a 160Gb of bandwidth to each 4U chassis.

 

Disk Expansion Module.

Adds up to another 40TB of storage capacity to reach 600TB Max, Support for 4TB, 6TB, 8TB, 10TB drives

 

I/O Expansion Module

In order to allow for the maximum amount of flexibility with regards to connectivity or acceleration Cisco have the option of an I/O expansion module to allow additional Ethernet or Fiber Channel (Target and Initiator) connectivity options.

Flash Memory from Fusion I/O or SanDisk are also supported.

Cisco UCS S-Series Configuration Options.

The figure below shows the various configuration options depending on how you wish to optimize the server.

Where does Cisco UCS S-Series fit?

Cisco are positioning the S-Series as a pure infrastructure play, they are not bundling any Software Defined Storage (SDS) software on it, as that space if filled with the Cisco HyperFlex Solution, but perhaps the S-Series could be an option for a huge storage optimized HyperFlex node in the future.

That does not of course preclude you from running your own SDS software on the s3260, like VMware VSAN for example.

And for clients that want that off the shelf pre-engineered solution then solutions like vBlock/VxBlock  or FlexPod are still there to fill that need.

One thing’s for sure still lots of innovation planned in this space, in the words of Captain Jean-Luc Picard ” Plenty of letters left in the alphabet”

    Does this mean Cisco is officially getting into the storage market?

    Looks like a descendent of the Sun X4500 that was introduced a decade ago. Today the use cases for servers with huge amounts of storage and huge internal bandwidth to that storage has matured, and they will fit a definite sweet spot including, of course, real-time analytics.
