UCS 40G and Upgrades...?

[visitor68]

Does the UCS now support 40Gbps uplinks on the 6100? If so, it is on the roadmap?

Also, there have been recent upgrades to UCS annunced about 2 months ago...what are they?

Thank you

40Gbps would just be 2 10Gb connections per FI? You can do that already. Up to 80 GB per chassis.

Quite excited that code level 2.0 I think it is comes out in September. 1.4.(3m) is the current I believe. Would love to get some pre-release notes on the new code level.

Hey Ex, (long time no talk!)

The next generation of UCS hardware will provide double the Chassis-Fabric Interconnect bandwidth from 80Gbps up to 160Gbps.  The Internal ports from the IOMs to each blade are quadrupled. 

The new hardware consists of:

- 6200 Fabric Interconnects 48 Port coming shortly (96 port version on the way) both with unified ports

- 2208 IOM.  Eight uplink (towards FI) interfaces verse the existing four. Multi-lane host facing server interfaces (4)

- 2108 Second Gen VIC - which will have increased capatity for virtual interfaces (256) as well as support for VM-FEX

The Chassis' backplane was built from day 1 to support 40GB, so the only upgrades are to the IOM and blade adaptors.

The uplinks between the Chassis and FI's are still 10G interfaces, just more of them (along with increased port density on the Interconnects themselves).

There's also a mess of great new software features for the 2.0 release including iSCSI boot, disjoint L2 support and some other cool surprises ;-)

Regards,

Looking forward to version 2.0 of code. The disjoint L2 support will be nice.

Has the capacity of the UCS chassis been increased to support more than 8 HH servers? With the increase in uplinks on the 2208 FEX modules, one can achieve an OS ratio of 1:1, but is that really the goal or have the number of servers also been increased? So, in other words, more uplink BW but more servers, too....?
