of the performance offered by 4 Gbpstechnology. There are two ways tomeasure performance of an SANdevice: Megabytes per second (MBps)and input/output per second (IOPS).The IBM DS4800 4 Gbps SAN producthas very impressive performancenumbers. It is designed to offer up to1724 MBps throughput with upto 575,000 IOPS. A 2 Gbps storagearray can require up to twice as manyhost ports as a 4 Gbps array to deliverthe throughput of four 4 Gbps ports.This frees up ports in the SAN for eacharray.On the host side, if a server requiresmore than two 2 Gbps host busadapters (HBAs) to attain the requiredperformance (a server should have atleast two HBAs for availability), thenthat number can be halved with4 Gbps. Fewer HBAs help lower thenumber of switch ports used and canhelp reduce overall cost.Business continuityIBM System Storage DS4800 disk storagesystem offers the latest innovationfrom IBM in storage infrastructure performanceand management, helping toenable you to develop storage environmentsthat can deliver unprecedenteddata availability. High availability andreliability with a choice of multiple RAIDlevels and redundant, hot-swappablecomponents—the DS4800 disk storagesystem can help you maintain dataavailability and security, enablingenterprise-inspired levels of reliability,availability, security and serviceability.Resiliency features—The DS4800 diskstorage system is designed to deliverpowerful, dynamic capabilities that helpprotect data and prevent failure, notjust respond and recover. Disasterrecovery—point-in-time copying withIBM FlashCopy®, copy a volumewith VolumeCopy and remote mirroringwith Enhanced Remote Mirroring canprovide enterprise-class disaster recoverystrategies.One of the key advantages of theDS4800 4 Gbps technologies is that itis backward compatible with 2 Gbpsand even 1 Gbps. That means youneed not replace your entire SAN with4 Gbps technology, but you can addthe new technology incrementally. Ofcourse, 4 Gbps products will slowdown to the 2 Gbps or 1 Gbps speed ifthey are connected, but zoning canallow a rolling upgrade strategy withminimal disruption.Information lifecycle management (ILM)Information is the lifeblood of anon demand business. With theIBM DS4800 offering 4 Gbps technology,the IBM DS4000 series can allowflexible access and a broader range ofscale and performance options, providingstructure and context to your enterpriseinformation. As a result, you havethe freedom to build data managementstrategies that align with your evolvinginformation demands.Information is the lifeblood of anon demand business, and how thatinformation is managed can become akey strategy of the IT organization. TheIBM DS4800 is designed to accommodatethe changing value of data overtime while maintaining data availability.IBM System Storage DS4000The IBM System Storage DS4000series is well known for exceptionalperformance, robust functionality andunparalleled ease of use. Building onthis successful heritage, the newDS4800 combines next-generation4 Gbps Fibre Channel (FC) technology.The DS4000 series proven storagetechnology can create a systemdesigned to handle some of the mostcompute-intensive workloads and providerobust functionality while maintainingavailability.
