Access "How to design a core/edge SAN"
This article is part of the Vol. 3 No. 9 November 2004 issue of Disaster recovery planning options on a shoestring budget
This article first appeared in "Storage" magazine in their November issue. For more articles of this type, please visit www.storagemagazine.com. What you will learn from this tip: How to use the SPICE algorithm to simplify the process of designing a large core/edge SAN. Three storage area network (SAN) architectures have become prominent: island, collocated and core/edge. Each topology serves a particular niche, but of the three, the core/edge SAN is the most scalable and widely deployed. Designing a large core/edge SAN can be a complicated process, but the SPICE algorithm greatly reduces the complexity. The S variable is the number of servers that will be migrated initially to the core/edge SAN. It's the milestone by which the implementation project is measured. As with any project, server and capacity requirements may change during the implementation, but setting the S goal early in the planning phase will establish a clear completion point for the project. Because a goal of the core/edge SAN is to keep the storage port as close to full utilization as ... Access >>>

Modern storage arrays offer disk types to meet any need -- costly Fibre Channel (FC) disks for high-end applications requiring superior performance and availability, and lower-priced SATA disks for less-critical data. The arrays also come with mixed RAID configurations. But selecting the right mix of disks and RAID levels requires understanding the impact of those decisions.
