Three-step SAN deployment maximizes benefits
Phasing in a SAN offers a number of benefits and can maximize the return on investment, according to SAN maker Gadzoox Networks Inc. (www.gadzoox.com). A phased deployment also reduces risk and eases the learning curve, the company says.
The logical place to start is with a department in the enterprise that has a managed or unmanaged hub, and connects the existing server to the new SAN, which is connected to the storage devices. Using existing SCSI arrays with a protocol converter helps to protect the existing storage investment and eases implementation.
Once departments are connected to SAN hubs, the next step is to link the departments together with a storage switch. This expands the capabilities of the SAN and lets the departmental hubs be connected with a backup link for higher availability.
The third phase is to install a larger, backbone, switch to make data available throughout the enterprise over the SAN and fully reap the benefits of a SAN.
The strategy is described in more detail in a Gadzoox white paper titled "Getting the Most from Your Storage: How to Deploy a SAN" which is available on the Gadzoox web site at www.gadzoox.com.

Every month, enterprises require more information, delivered faster, with greater reliability--and traditional data storage methods no longer suffice. Enter the Storage Area Network (SAN), which can store enormous amounts of data, serve it at lightning speed, scale to meet accelerating growth, and deliver unprecedented reliability. Now, there's a complete guide to SAN technology for every IT professional and decision-maker. Storage Area Networks covers it all: key concepts, components, applications, implementation examples, management, and much more.
