One of the main things I was asked during my work time Booth office processing center at Synergy Barcelona were on Cisco Unified Computing System (UCS) with NetApp storage solution and the solution with the PowerEdge EqualLogic storage solution. Participants are interested in knowing what Synergy areas were running off the two solutions, why the equipment was selected and how it was configured. I will cover the Cisco UCS solution in this blog.
The relationship between Citrix, Cisco and NetApp is not new. At Citrix, we made an announcement in 2010 of our joint partnership efforts with Cisco on Cisco Desktop Virtualization Solution with Citrix XenDesktop. In addition, we have collaborated with Cisco on the desktop processing center at Synergy San Francisco. Much of the equipment that Cisco has provided Synergy San Francisco has also been used in Barcelona. However, there were some slight changes since we wanted to show the key areas of synergy as being "powered by Citrix."
Synergy Barcelona Planning began almost immediately after Synergy San Francisco, during which time discussions between the Citrix desktop transformation team and Cisco and Dell focused on what we could do differently and better than before. It was agreed to highlight the benefits of desktop virtualization by hosting positions work and applications for key user groups - including registration, access to Internet and cabin crew Our Citrix architects began designing the infrastructure, and determined the material resources needed for the construction.. material resources were based on many factors, including of vCPUs, vRAM, IOPS disk and storage to support a XenDesktop 5.5 environment using machine Creation Services.
When we presented our demands to Cisco, their engineers have determined the best equipment to conduct the Desktop Transformation solution. Accordingly, the Cisco UCS solution consisted of the following:
- (2) Cisco UCS 5108 server chassis with (8) B250-M2 blades RAM 192GB each
- (2) Cisco UCS 60 fabric interconnects
- (2) NetApp FAS3240 storage systems SAN
- (2) Shelves NetApp DS4243 disk (each with 24x 0GB drives)
- ( 1) Cisco Nexus 5548 Ethernet 10Gps / FCoE switch
Doubling the key equipment has allowed us to build a cluster configuration for redundancy and high availability. Communication between the blades and the switch ran on 10Gb Ethernet connections. FCoE 2 x 10Gb / were used between the interconnections and FAS3240s NetApp fabric. Since Hyper-V does not support NFS we used iSCSI. The management system was processed by the Cisco UCS Manager.
Once we configured the hardware, we built six Hyper-V hosts with 6 TB of storage, since that was all we needed for virtual desktops. Virtual desktops were distributed equally among three CSVs to ensure that we would not have problems with disk latency due SCSI commands or queues. Using XenDesktop 5.5, we created MCS random Pooled desktops for Internet Access Centre, the Cisco booth, Synergy and other suppliers. This configuration provided us with the ability to rotate over 0 MCS generated virtual desktops, with the RAM being the limiting factor.
Our thanks go to Cisco and NetApp to provide the material necessary for half the desktop transformation Center, and to all our partners who helped make Synergy 2011 a great success. For more information about Cisco Unified Computing and products please visit Cisco UCS
