Encryption, which is critically important to security of the virtual environment. Some storage arrays protect the data while it's at rest, which means theft of the array, or of an individual drive, can't leave the organization at risk. Good encryption techniques keep companies from falling victim to preventable storage compromises.
7. What is
Microsoft'scontribution to the storage arena?
Storage space - aggregates all available and supported storage into a single pool or storage. This feature can help organizations that can't afford a traditional SAN gain access to centrally managed storage at a much lower cost.
TRIM/UNMAP - Windows Server 2012 implements an UNMAP capability that allows the thin provisioning process to reclaim previously used space that has since become unused.
Deduplication - added to the operating system in Windows Server 2012. It's a post-process deduplication method that works on a file basis by breaking files down into small chunks and running these chunks through the deduplication engine.
8. What storage transport mechanisms are available?
The storage transport is one of the most challenging decisions for a virtualization administrator, and the storage choice will directly impact how the virtual machines are created. Choices include:
Direct Attached Storage, directly attached to servers and possibly consisting of hard drives plugged directly into slots in the server, or an external storage device connecting to the server with SAS cables, for example. Direct attached storage is useful for a small environment.
Network attached Storage (NAS), generally file-based devices that operate using SMB or NFS over TCP/IP networks. NAS devices are typically standalone appliances that reside on the network and, in most cases, can be used to store virtual machines.
Storage Area Networks (SANs), used in data centers for a long time to provide robust, highly available shared storage environments. The three primary types of SANs include iSCSI, Fiber Channel, and Fiber Channel over Ethernet (FCoE)
9. What different kinds of storage arrays are on today's market?
There is a type of storage out there for just about every need. Balancing understanding of the different types of storage arrays with the organization's specific needs will help administrators make the right choice. Storage arrays on the market today include:
Hard disk-based arrays, excellent for capacity, poor for performance
Hybrid storage arrays, very good for both capacity and performance
All Flash storage arrays, poor for capacity, excellent for performance
Server-side flash, poor for capacity, excellent for performance
Leveraging a Triple-A approach for smooth, effective storage infrastructure management:
Once the concepts of storage configuration and optimization have been mastered, the next step is to keep the storage infrastructure running smoothly so that it fully supports both virtual and physical data center infrastructure. A Triple-A approach - incorporating predictive analytics, actionable advice, and intelligent automation - will lead to a flexible infrastructure in which capacity can be scaled up or down as business requirements change, while simultaneously focusing on data center cost optimization.

'As the virtualization manager's role edges more and more toward managing the infrastructure as a whole, it's crucial for that individual to have broad knowledge of all aspects of the infrastructure. The virtualization environment requires storage to operate, and the infrastructure's performance and availability are closely tied to the storage configuration, as well. We offer these nine storage concepts to help the infrastructure manager gain the knowledge necessary to keep the storage infrastructure running smoothly, so that it fully supports both the physical and virtual data center infrastructure.'
