VMworld 2014: Why storage admins will love VVOLS

Why storage admins will love VVOLS

VMware has announced a beta of their long talked-about Virtual Volumes (VVOLs)  alongside the new beta of vSphere 6. So what are VVOLs, and how do they help you?

Get the benefits of shared storage (without adding hardware costs) [VMware]

Shared storage

So you’ve decided to virtualize your storage. Virtualization often means dealing with complex shared storage for the first time. For example, a SAN configuration may require an FC Switch, a Server HBA, FC cables, and an external RAID storage hardware. Its complex, it takes up space, and it isn’t very efficient.

What if there was another option available? One that allowed to you create a software-based shared storage solution that acted like a SAN and not like a traditional Virtual SAN Appliance?

This solution is closer to reality than you may think.

Before your road trip to the cloud, clean up under the hood. [Cisco]

Clean up under the hood

So you think you’re ready for your journey to the cloud. Before you hop in and shift gears, there’s a little engine maintenance in order.

As the amount of data, applications and servers in data centers have increases, too have corresponding storage and networks. One of the challenges of storage-specific networking protocols is that they’re incompatible with the dominant server networking protocol: Ethernet. Organizations have therefore had to deploy entirely separate physical networks in their data centers: an Ethernet LAN for server connectivity and a SAN for storage. Although the two mostly perform the same function, they have separate physical networks, with separate switches, cabling, networking hardware and connections into each server. This creates a lot of potential complexity that is an easy target for elimination.

Your data center has gotten crowded.

Because these networks use different protocols, SANs and Ethernet varieties often need to be maintained by separate teams with different skill sets. Not only is this inefficient because it requires potentially redundant network management staff, now adding, moving, or changing physical servers and connections needs coordination between two groups. That makes it costly and inefficient for organizations and reduces their flexibility to adapt to changing business needs – like getting into the cloud. [Read more…]
