Benefits of a Converged Blade Enclosure Ecosystem

While server virtualization decreases the number of physical machines in a data center, it does not necessarily diminish the need for other pieces of IT equipment. For example, in order for a traditional server running multiple virtualized workloads to be effective, that hardware may still need multiple switches and storage devices, according to Apple co-founder Steve Wozniak. This can diminish the benefits of virtualization, forcing data centers to purchase additional components.

“[T]here are bottlenecks from sharing these resources,” Wozniak said in a February video tutorial about virtualization. “At times, there isn’t enough throughput to get stored data into the CPU to be processed, preventing each [virtualized] application from running smoothly.”

To address this issue, data centers need to increase the amount of storage within the physical server running the virtualized workloads, Wozniak said. This way, businesses can realize the benefits of virtualization, needing far less hardware in the data center facility. However, a key downside to such a setup is that these data storage options can be prohibitively expensive, and it may not always be possible to sync up added storage solutions with legacy IT equipment.

How a Blade Enclosure Solves Virtualized Problems
The most effective solution to virtualization’s storage problems is to upgrade the blade enclosure to store more hardware in a single chassis. According to Shanky Chandra, Dell Tech Center’s EqualLogic Product Manager, this setup may be a more practical way for data centers to maximize the return on investment realized from a virtualization initiative.

“People [in the past] had to use external storage in order to work with their compute nodes, and the reason they need shared storage in the first place is because … you have virtual machines, which could be created in any physical machine, all of them having visibility into one single shared [external] storage,” Chandra said. He added, “Bringing the shared storage inside a blade chassis is the right next step because a virtual administrator having a blade chassis for convergence is going to now be able to utilize the shared storage from inside the blade chassis and be able to provision it to the virtual machines, and be able to dynamically do the V motions – everything from inside the chassis – without having to depend on any externals at all.”

Data centers should place more storage into a single blade enclosure.Provisioning a blade enclosure in this manner will only become more necessary in the coming months and years as data centers further rely on blade servers running virtualized workloads to keep enterprise IT systems running. Young-Sae Song, Corporate Vice President of Product Marketing at Data Center Server Solutions for AMD, wrote recently in Data Center Knowledge that virtualization as a company-wide goal can only work if the servers are running at maximum capacity, and this will happen only if the blade enclosure being used is built and maintained with these needs in mind.

Regardless of the type of blade server utilized, a data center running virtualized workloads will likely need to upgrade its storage capacity. Putting this storage inside the blade enclosure is not a necessity, but such a move can go a long way toward dramatically improving a data center’s overall effectiveness.

“Key to meeting performance and economic goals is the interconnect between the processors, and it is this technology that will differentiate servers, with bandwidth and protocol design playing pivotal roles in overall system performance,” Song wrote. “The ability to have thousands of cores in a rack increases the need for tighter integration between bare metal and management software.”

In the Data Center: Is Safe, Safe Enough?

It may come as little surprise that at ServerLIFT headquarters, the majority of our conversations revolve around data center safety. It’s the reason we originally designed the ServerLIFT data center lift. No one had made anything like it before. We saw a clear need for a lift that could function effectively in the data center environment without putting anyone at risk.
