Cisco and VMware Submitted VXLAN for Open standard

Posted on September 2nd, 2011 in Announcement, Data Center, vCloud, Virtualization | No Comments »

Interesting announcement from Cisco and VMware during the VMworld 2011 which was regarding the VXLAN capability. Both company had invited a group of product principle together to submit the VXLAN to IETF for approval as a standard for future.

Let’s talk a little bit more about what is VXLAN and why do we need that. As of today, DR solution are commonly deploy by every enterprise environment. Did you realize 1 of the biggest challenge which always happen on the DNS record, hard coded IP segment, subnet and VLAN which always require human interaction to manually change it, to allow a success fail over of the DR scenario? Well, I think this is just 1 of the major issue commonly face. With Cisco Nexus 7000 come with OTV (Overlay Transport Virtualization) which allow you to stretch the Layer 2 traffic over Layer 3, with minimal bandwidth requirement. Cisco had done a great job to the enterprise to address this, which now you can have both side learning the same VLAN, Subnet and ip address. A DNS and ip changes is no longer require as both end are transparent with similar VLAN.

Reduce numbers of Server Racks in Data Center

Posted on June 13th, 2009 in Data Center, Hardware, Industry News, Virtualization, vSphere | No Comments »

With my last 3 years of experience, I had seen numbers of companies require significant expansion in the data center to support the business growth, just because of the additional 200 to 2000 servers or storage shelves they need to put in to the data center. With the technology today, it does help us to reduce the space we need to slot in the servers, and storage thanks to the success of virtualization and higher capacity disk drives in the market. To run a full solution of data center with less number of server racks for SME and enterprise, will no longer be a dream due to some facts below,

  1. Higher consolidation ratio in virtualization with the latest CPU, memory and servers performance
  2. Higher capacity disk drive which significant reduce the number of storage expansion require
  3. Virtual I/O which allow the higher utilization of the available bandwidth in data center
  4. UCS to provide consolidation and higher capacity of bandwidth to support network and storage utilization in the data center

Consolidate Server Network Virtualization and Storage

Posted on January 22nd, 2009 in Data Center, Hardware, Industry News, Server, Virtualization | 1 Comment »

Latest news from Cisco which confirm the release of Code Name California by early of March 2009. The solution will provide integration for Data Center Servers, Network Management, Virtualization and Storage Management from 1 console which the vendor believe to simplify the IT management which we had suffer for Years. HP is currently working on the product which provide the same features as Cisco California did. IBM will also soon to join the competition of this product range. With this technology in place, it may change the environment significantly for the next generation data center and my personal point of view is still the cost, features and reliabilities of the products. It will be good for consolidate with acceptable pricing and reliabilities especially at the current economy. Anything that help to save cost will be the top priority to be considered for IT spending.
