New Generation of Cisco UCS Virtual Interface Card 1240

Posted on April 26th, 2012 in Announcement, Data Center, Industry News, Server, Virtualization | No Comments »

Cisco UCS had updated the product line up with VIC 1240, VIC 1280 and LOM expander which allow a single half width blade to aggregates up to 80Gbps total bandwidth to deliver high performance and high throughput requirement for the server system.

The New VIC 1240 come with the following capabilities.

 

Advanced Support for Virtualized Environments

The Cisco UCS VIC 1240 implements the Cisco VM-FEX, which unifies virtual and physical networking into a single infrastructure. It provides virtual-machine visibility from the physical network and a consistent network operations model for physical and virtual servers.

The Cisco UCS VIC 1240 supports VMware’s VMDirectPath with vMotion technology, which allows it to:

  • “Pass through” the hypervisor layer
  • Provide near-bare-metal performance for unified computing systems
  • Integrated modular LOM for new generation Cisco UCS blade servers
  • Delivers up to 80 Gbps aggregate bandwidth to the servers, with the use of an I/O expander in the optional mezzanine slot
  • Near bare-metal I/O performance
  • Ease of management
  • Exceptional network visibility
  • support  Up to 256 dynamic virtual adapters and interfaces

Cisco UCS Product Update with B200M3

Posted on March 9th, 2012 in Announcement, Industry News, Server, Virtual Desktop Infrastructure, Virtualization | No Comments »

I just received an email from my Cisco Counter Part today, which Cisco had released the B200 M3 to their UCS line up. First thing I did, is to launch the Netformx design tools from my Laptop which provide myself the direct access to the latest configuration and price list online and authenticated by Cisco.

Cisco UCS added new Fabric Interconnect to the Product Line

Posted on August 24th, 2011 in Announcement, Data Center, Server, Virtualization | No Comments »

Cisco had recently added new Fabric Interconnect to their product line up which provide more choice to their client to be consider for their deployment. Previously there were only 6120XP and 6140XP in place for the Fabric interconnect architecture as part of Cisco UCS. The new Fabric Interconnect 6248UP which provide 32 ports FCoE with additional 16 ports expansion module on unified port available which support FCoE, LAN and SAN FC with appropriate module.

While introduce new Fabric Interconnect, the IO Module for UCS Blade Chassis had been further enhance with 2208XP which provide 80Gbps throughput per IO module, and allowed up to 160Gbps per chassis. This option will allow users to provide higher throughput to the blade infrastructure which require more than 80Gbps per chassis.

Microsoft 2008 Cluster Bugs

Posted on August 17th, 2011 in Operating Systems, Server, Tips | No Comments »

Went through a marathon troubleshooting with my client for the past 1 week to figure out the reason why a cluster failed in place and it could not easily rebuild back after 1 of the node evicted. We had gone through the process to re image both nodes and rebuild from scratch. Follow exactly the best practices and run through the cluster validation without any error. While we try to form the cluster, the system keep provide an unknown error which do not share much information from log. It just keep telling you that the node is not reachable or unauthorized due to security setting.

After few nights of troubleshooting, I was running out of clue. Came to the sudden, I accidentally search the computer name in AD under the category of Users object group, and I found an user account been created in AD with the same name as we define on the cluster name. I was wondering whether this could caused the confuse to the system. Therefore, I was suggesting to remove the user name temporally as it was not use at the moment and tried to reform the cluster. Guess what, the cluster form up as it needed to be in less than 1 minutes. We were so happy to end the marathon troubleshooting every night well and we were also very pissed off with the bugs we face here.

NIC teaming policy for Servers

Posted on May 27th, 2011 in Server, Tips | No Comments »

NIC teaming is common practice in Data center to avoid link drop due to hardware failure on NIC or Switches. While choosing the teaming policies or architecture consideration, Network Architecture and configuration is the most important thing for you to look at. I will suggest all of us to consider the layer 2 and Layer 3 configuration before jump in to the server teaming policy as different configuration on the network side could caused an outage to the network as well as the servers which both are always relate together.

Beside that, strongly urge all the users to look in to the application tier as well, which there are some applications may not support ip-hashing which could end up confuse the switches and create looping. Most Servers require NIC teaming just for HA but not aggregation through put, if that the case, choose wisely what you need rather than what is good to have to prevent unnecessary down time to the infrastructure.
