Data center expenditures are expected to become the largest IT cost center within organizations, thus highlighting the need for significant data center transformation. Being able to bundle performance, virtualization, and dynamic provisioning functionality in your storage architecture will be essential in controlling costs, addressing poorly performing applications, and providing true quality of service to these applications.
Direct Attached Storage (DAS)
DAS attaches directly to a computer system. The interface of choice for these devices was SCSI and they were reserved for database type uses where the speedy input and output of data was a key to user friendly implementations. The spectrum of hardware and uses has increased, and the deployment of storage strategies has blended to the point that this term now encompasses a much larger variety of products.
Network Attached Storage (NAS)
NAS attaches to a network via the network’s own cabling system and protocol. These products are assigned IP addresses and thus become potential file storage for any client user on the network. In effect, they are file servers that do not require the licenses associated with bringing another full server online. Besides the obvious savings associated with this, NAS products offer advantages in expansion and fault tolerance that make them a popular tactic in storage deployment.
Backup Solutions employ the simple fault tolerance tactic of duplication to assure data continuity when failure occurs to a computer system or network through loss, corruption or destruction. The importance of information in today’s business environment is such that no business can afford to lose access to its own without dire consequences.
Storage Area Network
A network that is dedicated to handling Storage functions is called a Storage Area Network (SAN). A SAN performs the same function as DAS or SAN devices do, it makes data storage available to users. DAS and NAS strategies are effective at delivering storage to users but as the quantity and locations of data grows, the man hours and network traffic used to support it become unwieldy. A SAN is a flexible, intelligent, and easy-to-manage storage solution that allows you to give structure and efficiency to your data availability while reducing operational expense.
Storage software solutions help you get more value from your current storage. They defer future storage investments and put your storage expertise to the best use — managing instead of reacting. From the simplest automated back-up function to complex virtualized remote storage solutions, the correct storage software will give users fast, safe and secure access to their data.
