Huge Data Sets Require Fast Reliable Storage

Securely storing your precious data takes a high priority for your IT department, require fast reliable storage. There are several central issues to consider when purchasing data storage, and they force your hand when making a decision. The first is speed of access to that data, and the second, even more vital, is protection.

The principle of backup storage is that data should as much as possible be in at least two places. For extremely important data, offsite backups become important. These place a copy of the data in a distant location. Free storage is available for small amounts of data, but when dealing with huge data sets, commercial solutions become necessary.

Fast Reliable Storage

Need Fast Reliable Storage?Backups are sometimes stored on magnetic tape. Although these backups are slower to write and read, they are better for long-term storage. Using hard disk drives is more common. However, these are somewhat more sophisticated than a simple hard drive connected to a simple computer. Most archives consist of storage racks that hold discs in a RAID pattern. Although RAID is sometimes used to increase the size of desktop hard drives, its primary purpose is to increase the safety and security of data by storing not just one copy on one drive, but multiple copies. If one drive in a storage rack fails, it can be switched out quickly and easily with minimal to no data loss. If the archive is off site, then fast network access becomes important. This reduces the chance of data loss due to natural disasters, power loss, or even human actions such as theft. This is also sometimes called cloud storage, and large companies may keep backups in three or four locations. As cloud storage has inherently slower access, it is normally only used for secure backups or virtual-ization. Dell data storage offers these kinds of cloud solutions. They also include large storage racks designed to hold large quantities of data. On top of physical storage, there is also software available that allows faster retrieval of data from both local storage and the “cloud.”
