HP Flex 10 vs VMware vSphere Network I/O Control for VDI

I once was a huge fan of HP’s Virtual Connect Flex-10 10Gb Ethernet Modules but with the new enhancements to VMware vSphere 5, I don’t think I would recommend for virtual environments anymore. The ability to divide the two onboard network cards up to 8 NICS was a great feature and still is, if you have to do physical deployments of servers. I do realize that there is the HP Virtual Connect FlexFabric 10Gb/24-port Module but I live in the land of iSCSI and NFS so that is off the table for me.

With vSphere 5.0, VMware improved on its Continue reading →

Why Blade Servers Will be the Core of Future Data Centers

In 1965, Gordon Moore predicted that engineers would be able to double the number of components on a microchip every two years.  Known as Moore’s law, his prediction has come true – processors are continuing to become faster each year while the components are becoming smaller and smaller.  In the footprint of the original ENIAC computer, we can today fit thousands of CPUs that offer a trillion more computes per seconds at a fraction of the cost.  This continued trend is allowing server manufactures to shrink the footprint of the typical x86 blade server allowing more I/O expansion, more CPUs and more memory.  Will this continued trend allow blade servers to gain market share, or could it possibly be the end of rack servers?  My vision of the next generation data center could answer that question.

Dell Network Daughter Card (NDC) and Network Partitioning (NPAR) Explained

If you are a reader of BladesMadeSimple, you are no stranger to Dell’s Network Daughter Card (NDC), but if it is a new term for you, let me give you the basics. Up until now, blade servers came with network interface cards (NICs) pre-installed as part of the motherboard.  Most servers came standard with Dual-port 1Gb Ethernet NICs on the motherboard, so if you invested into a 10Gb Ethernet (10GbE) or other converged technologies, the onboard NICs were stuck at 1Gb Ethernet.  As technology advanced and 10Gb Ethernet became more prevalent in the data center, blade servers entered the market with 10GbE standard on the motherboard.  If, however, you weren’t implementing 10GbE then you found yourself paying for technology that you couldn’t use.  Basically, what ever came standard on the motherboard is what you were stuck with – until now.

Why Are Dell’s Blade Servers “Different”?

I’ve learned over the years that it is very easy to focus on the feeds and speeds of a server while overlooking features that truly differentiate.  When you take a look under the covers, a server’s CPU and memory are going to be equal to the competition, so the innovation that goes into the server is where the focus should be.  On Dell’s community blog, Rob Bradfield, a Senior Blade Server Product Line Consultant in Dell’s Enterprise Product Group, discusses some of the innovation and reliability that goes into Dell blade servers.  I encourage you to take a look at Rob’s blog post at http://dell.to/mXE7iJ.

Customer Success Story with Dell, Citrix and VMware

I always find it interesting to hear how customers are using blade server technology “in the real world.”   Brickworks, a $1.7 billion Australian brick company with over 60 locations and 1,000 employees, recently provided The Australian with details about how Citrix XenApp Enterprise combined with VMware vSphere and Dell rack and blade servers helped develop a more efficient workplace for its employees.  Continue reading →

Will the New VMware vSphere 5 Licensing Affect Blade Vendors? (PART 2)

Since my last post, I heard lots of rumors that VMware would make some changes in their new licensing model. Well, this week VMware made an official announcement of changes and posted here.

VMware made very clear that all the changes were motivated by the feedbacks they have received: Continue reading →

A Look at Intel’s Cloud Builders Initiative

In case you haven’t heard, “cloud” discussions are here to stay and everyone has their own recommendations for you to start building your cloud environment, but which is best for you?  Intel has created the “Intel® Cloud Builders” program aimed at making it easier for you to build, enhance and operate cloud infrastructure.

Another Free Chassis Offering – Is Cisco Driving These Offers?

I was recently on one of those calls from HP “checking in”. If you are an HP customer you may know these calls start off with something like “We know you spent money on HP last quarter so how many people from this company will have to pester you until you buy more stuff from us?” One of the things the HP rep mentioned towards the end the process, however, is that until October HP is now offering a free blade enclosure with the purchase of four HP BL460’s.  Continue reading →
