In the storage industry, we hear the term "migration" all the time - almost every day. One of the first visuals that comes to my mind whenever I hear that word is a neatly formed "V"-formation of geese or ducks flying south for the winter. The "V" formation is a very efficient way to fly long distances. One bird's wing-flapping causing a vortex, giving the bird directly behind effortless lift. The group works together in this way to migrate vast distances in a short amount of time while expending as little effort as possible. Just as bird migration is inevitable, so to is data migration - no matter what form it's in. In the storage world, this might mean you need to migrate older tape formats to a more current one to support the new tape drive you've just bought, or migrate data from an older storage array to a new one. Too often, storage strategies are developed wi... (more)

How to Simplify Off-Site Backup for Virtual Environments

If you happen to be managing a virtual server environment, such as VMware or Hyper-V, you are probably aware of the importance of backup software to protect your valuable applications and data in case of disaster. You may also be keenly conscious of the unique needs that virtual server environments pose, such as virtual machine sprawl, contention for server resources and spiraling data growth (often duplicate data), in which case there is probably no need to spend a lot of time touting the benefits of Veeam Backup & Replication. Over the past few years, Veeam has become the lead... (more)

Cloud Storage: Where’s the ROI?

Return on investment (ROI) of using the cloud has recently become a popular topic of discussion, though not in a way you might expect. An interesting article by JP Morgenthal entitled There is no ROI in cloud computing presents the opinion that cloud services simply have no ROI. A second article by Joe Onisick entitled Private Cloud: It’s Not About ROI effectively repeats a similar message in the context of private clouds. While both pieces appear controversial on the surface, they accurately portray that cloud infrastructure is not an investment – rather, cloud offers a way to ... (more)

Breaking the Storage Array Lifecycle

Anyone who purchases storage arrays is familiar with the many advantages of modular storage systems and storage area networks. However, they may also be familiar with one of the less desirable attributes of storage arrays: the typical three- to five-year lifecycle that forces decommissions and mandates upgrades on a regular basis. With many organizations expanding their need for storage by 20-60% on an annual basis [1], outgrowing capacity of existing storage arrays is a regular occurrence, effectively rendering upgrade cycles to be a fact of life. Although decommissioning and u... (more)

Cloud SANs: What the Data Storage Vendors Forgot

Storage area networks (SANs) have become the ubiquitous deployment model for block data storage systems, interconnecting formerly siloed storage arrays with a common high-speed network running standardized protocols such as Fibre Channel or iSCSI. It was over a decade ago that the ability to connect multi-vendor storage arrays into a common network proved revolutionary and changed the way storage arrays were configured and consumed by businesses. However, with continuing advancements in cloud storage solutions, IT administrators are now rethinking the traditional SAN. As with ma... (more)
