The Dell EqualLogic FS7500 is a unified, scale-out NAS solution that works with EqualLogic PS Series
arrays to combine both NAS and SAN storage in a single, flexible architecture designed to optimize both
performance and capacity. While many storage solutions tend to experience performance degradations
as you increase their capacity, the FS7500 offers almost linear scalability; that is, as you increase the
number of controller pairs or EqualLogic PS Series arrays, the FS7500 delivers a proportional increase in
storage performance. This is a key feature because consolidating virtual workloads can cause
unexpected demand bursts in your storage capacity and performance. The scalability of performance
with capacity eases this common stumbling block.
The FS7500 system can be quickly added to an existing EqualLogic SAN environment to create a NAS
service. Because workloads in virtual environments can be deployed or moved quickly to meet business
needs, it is not uncommon to experience high volatility in storage demand. As a result, the ability to
add or move NAS or SAN storage quickly and easily, without disrupting operations, is a great
advantage—especially as more and more applications are virtualized.
