IT organizations have gained significant benefits as a direct result of server virtualization. Server consolidation reduced physical complexity, increased operational efficiency, and the ability to dynamically re-purpose underlying resources to quickly and optimally meet the needs of increasingly dynamic business applications are just a handful of the gains that have already been realized.

Now, VMware’s Software Defined Data Center (SDDC) architecture is extending virtualization technologies across the entire physical data center infrastructure. VMware NSX, the network virtualization platform is a key product in the SDDC architecture. With NSX, virtualization now delivers for networking what it has already delivered for compute and storage.

In much the same way that server virtualization programmatically creates, snapshots, deletes and restores software-based virtual machines (VMs), NSX network virtualization programmatically creates, snapshots, deletes, and restores software-based virtual networks. The result is a completely transformative approach to networking that not only enables data center managers to achieve orders of magnitude better agility and economics, but also allows for a vastly simplified operational model for the underlying physical network.


With the ability to be deployed on any IP network, including both existing traditional networking models and next generation fabric architectures from any vendor, NSX is a completely non-disruptive solution. In fact, with NSX, the physical network infrastructure you already have is all you need to deploy a software defined data center.

I’m very busy with preparing my upcoming "Mythbusters Goes Virtual" VMworld session which will go deep into a few specific well known vSphere myths. The myth busting will be done by Mattias Sundling and me. I’ll have the honour to debunk the fact that RDM offers a better performance compared to VMFS. My lab wasn’t equipped with a device that offers RDM storage and VMFS storage but luckily my good friend Duco Jaspars brought my into contact with Iomega’s Benelux country manager Filip Joly.

Filip has offered me a brand new StorCenter px6-300d, this is a high performance business class desktop device, ideal for small-to medium sized businesses and distributed enterprise locations like branch and remote offices, for content sharing and data protection. Powered by EMC storage technology and with up to 18TB of storage capacity, including a diskless option, is easy to setup and manage, and affordable to own. This 2 part video demonstration shows you how to add an iSCSI drive to both the px6 and VMware vSphere.

Adding iSCSI Drives

1. To add an iSCSI drive, click  Add an iSCSI drive on the iSCSI page.
2. If your Iomega StorCenter px6-300d has multiple Storage Pools, select the desired Storage Pool from the drop-down menu.
3. Enter a name for the iSCSI drive. How you name your iSCSI drive will depend on your Iomega StorCenter px6-300d meeting one of the following conditions:

• If the iSCSI/Volume Name field displays by itself, enter a name for both. This field displays when your Iomega StorCenter px6-300d is new, has no existing volumes, and supports multiple volumes.

• If the Name field displays by itself, enter a name for the iSCSI drive. This field displays when your Iomega StorCenter px6-300d is new or being upgraded and has only one volume.

• If the Create a volume or Use an existing volume options display, select:

• Create a volume to create a new volume for your iSCSI drive. This option displays when your Iomega StorCenter px6-300d is new, or if you are upgrading your Iomega StorCenter px6-300d and it has available space in its Storage Pools.

• Use an existing volume to use an existing empty or shared volume. This option displays when you are upgrading your Iomega StorCenter px6-300d, have available space in your Storage Pools, and have already created multiple volumes. To use an existing empty volume, select iSCSI/Volume Name and enter a name for the iSCSI drive and volume. To use an existing shared volume, select Shared Volume, select the existing volume, and enter a name for the iSCSI drive.

4. Enter a size for the iSCSI drive.
5. Click Create to create the iSCSI drive.

When you’re building a new home lab or adding a new white box to your private cloud, you want to put as much memory into your servers as you can. It’s the same story as in most of the datacenters, CPUs are idling while your ESX servers are running out of memory. Intel has released a new chipset that might be worth a closer look. The Intel Desktop Board DQ67SW supports four 240-pin DDR3 SDRAM Dual Inline Memory Module (DIMM) sockets which can hold 8 GB each. That means 32 GBs of system memory based on  DDR3 1333 or 1066 MHz DIMMs on one board.
 
Based on the latest Intel® Q67 Express Chipset with Intel® vPro™ technology, Intel® Desktop Board DQ67SW is designed to showcase the superior performance quality of the 2nd generation Intel® Core™ vPro™ processor family, enhance office productivity, and lower the total cost of ownership for your business PCs with the newest Intel® Active Management Technology (Intel® AMT) 7.0.

Designed with exceptional stability and compatibility, Intel Desktop Board DQ67SW equipped with the latest SuperSpeed USB 3.0 and SATA 6 Gb/s ports with RAID support. Dual independent display capability with DisplayPort and dual DVI ports.

Chad and Wade demonstrate the Iomega StorCenter px6-300d at EMC World during the Chad's World presentation. Chad and Wade launched 100 VMs from the px6-300d. 

One of my students at last week’s VMware Technical Sales Professional training demoed me his home lab with a real great White Box. Alain used the Aspire X5810 - a multimedia-ready desktop flashing a cool, brushed-metal chassis and streamlined design. This desktop occupies just one-third of the space of a traditional PC. The default CPU is an Intel® Core™2 Quad Processor Q8300 (4M Cache, 2.50 GHz, 1333 MHz FSB), check this page to see if the CPU is Virtualization Technology (VT-x) compatible. The onboard network card isn’t supported by ESX4i, so you have to buy an additional Intel E1000.

Technical Specifications

Model Name: Aspire X5810
Processor & Chipset: Intel® Core™2 Quad processor (up to 95 W)
Intel® Core™2 Duo processor
Intel® G43 Express Chipset
Memory: Up to 8 GB of DDR3 1066 MHz SDRAM (dual-channel support on four DIMMs)
Storage: Serial ATA hard disk up to 1TB (ICH10)

A few days ago I’ve hooked-up my newly bought Intel SSD drive to one of my ESX server but didn’t realize it was the one with an ICH9 SATA controller. After some first tests I was a bit disappointed with the outcome, only 150 MB/Sec. After exchanging some email with Simon Seagrave over at techhead.co.uk who also has bought an SSD drive, I realized I was using the wrong ESX server. The SSD drive is now hooked-up to a server with an ICH10 SATA controller. I quickly fired-up the servers to see how fast the SSD drive is running now and it really matters. The difference is significant.
