The IBM TotalStorage DS4300 Express is designed to be an affordable, scalable storage server for storage consolidation and clustering applications. Its modular architecture which includes Dynamic Capacity Addition, Dynamic Volume Expansion and a turbo option can support e-business on demand environments by helping to enable storage to grow as demands increase.
The DS4000 EXP710 Express switched disk expansion unit has an ESM-embedded Fibre Channel loop switch. The loop switch creates what is essentially point-to-point Fibre Channel communication, allowing the ESMs and drives to operate as though they were on a private Fibre Channel arbitrated loop, but with the performance and diagnostic advantages of Fibre Channel fabric. A great advantage of the DS4000 EXP710 Express is a significant reduction in the number of Fibre Channel nodes on the drive loops.
