Xsigo on ESX 3.5 Prove of Concept

Posted on December 18th, 2008 in Virtualization | 2 Comments »

Personally, I just initiated the prove of concept with the local vendor in our environment regarding the Xsigo Virtual I/O integration into our existing Network, Fiber Channel and ESX 3.5 Virtualization server. I would like to share some of my finding which I think may be useful for reference purpose.

Before the approach on Xsigo, I am actually working on the new design plan to improve the performance and capabilities of the existing virtual infrastructure for the large scale virtualization in our environment. I am actually think about the Cisco director switch on Fiber channel and the network switches of 6509 with 10Gb module, but the cost of doing this, is really going to kill us for the current economy down turn. Suddenly, I been introduce by my buddy with this brand new products which I setup the POC now and I found that is more make sense to look in this product to unlock the under utilize bandwidth in our DC include both Network and Fiber Channel.

Advantages:

  1. HCA is cheaper than HBA as we may need 2 HBA per server for redundancy purpose, which only provide 8Gb bandwidth, the HCA will provide 20Gb per HCA, which will be powerful enough for virtualization purpose.
  2. HCA will combine both network and fiber channel capabilities, reduce cabling requirement and improve bandwidth utilization.
  3. With Vnic and Vhba, we will able to create and utilize existing available bandwidth by reduce the number of FC and Network switches in the Data Center.
  4. I will able to reduce the cabling from 18 to 2 HCA connection per ESX in my environment

I am currently stress test the performance on the Xsigo chassis on our ESX, interesting that it will not sacrifice the performance as it able to perform as same as the previous configuration we done. Now, it provide the opportunity for me to utilize the FC ports in my Data Center without increase the number of FC switches, which is currently 95% utilize. Imagine, with 4Gb FC for HBA, except the high performance database server, we will not able to utilize the storage bandwidth on each FC ports. Same time, the gigabit network, will not be consume for more than 10% most of time, will provide more resources for the system which require extra bandwidth in the data center. Xsigo has the intelligent to manage the bandwidth and assign as needed.

Tips: VM Network Problem

Posted on September 10th, 2008 in Tips | No Comments »

For some reason, when you require to clone or deploy a new VM guest using a template from one ESX host to another ESX host that having different network setup, you may have network problem.

Said for example, I have a SuSE Linux VM template sitting on ESX 1 which is only using “VMNetwork1” network setting. Whenever I clone or deploy this template to ESX 2 which is only using “VMNetwork2” network setting, I’m sure you will getting annoying error when power on the virtual machine.

You can’t change using “Edit Settings”.
