With over 12,000 attendees, VMWorld 2009 was definitely impressive. It was great to be there as part of the Cisco data center team and see Cisco continue to make progress into the server & virtualization space. A few exciting technology showcases & announcements that were exciting to me: VMWorld Data Center chose Cisco Unified Computing System (UCS) to virtualize and reduced an environment of 37,728 physical servers using 2,483 racks and 25,329 KW of power to 776 physical servers in 28 racks using 528 KW of power.


The etherspace has been busy with highlights, tips, and expectations of VMWorld 09 taking place at the Moscone center in SF starting August 31. I'd like to chime in and highlight technology areas that I'll be focusing on while I'm there next week. Cisco Unified Computing System (UCS) Cisco's entry into the server computing realm by providing a platform that unifies network, compute, storage access, and virtualization resources. A "wall of UCS" at VMWorld will showcase 16 racks containing 64 chassis, 512 blades, 4096 cores, & 24 TB of memory. This is where the VMWorld labs are run out of and it is expected that ~1500 users will be accessing the UCS systems at any given time through VMware View.

Wanted to share my thoughts around the launch of Cisco Unified Computing System (UCS) and my thoughts around what Unified Computing means to me... Unified Computing Vision: server virtualization using stateless servers with virtualized adapters, riding on top of unified fabric, provisioned through a single domain of management Virtualization today:

  • Memory & GigE connectivity limiting the # of VMs a given physical host can accommodate.
  • The “quick fix” approach is increasing the # of GigE ports connected to a physical host. It’s not uncommon to see a physical host with 2 x HBAs & 6+ x GigE (separating out mgmt, vmotion, prod traffic).
  • Result of “quick fix” = increased connectivity infrastructure cost (ie. 48-port GigE linecard = 8 servers!) plus operational cost around managing each NIC.
  • 10GE starting to make more sense, take a step further into unified fabric --> simplified cabling infrastructure & cost, 1 x CNA + 2 x CNA cabling per physical host
