scalability
As a company specializing in a variety of IT services, it is imperative that Impulse’s internal
infrastructure is sound and has robust data management tools available. Like many other IT
service providers, Impulse was originally a customer of legacy storage vendors. Impulse
started with the NetApp® Filer, however Impulse quickly out-grew capacity and, when it
came time to expand, Impulse faced a hefty price tag.
After its experience with NetApp, Impulse decided to try a different service provider:
EMC®. Impulse deployed the EMC NS352 Celerra to manage their data storage needs. Soon
Impulse discovered, however, that EMC’s technology had some technological short-comings.
For example, the EMC NS352 maxed out with 2 GB/sec
through put, resulting in networking bandwidth that was too
low.
When they calculated they would also max out their existing
storage, Impulse decided to evaluate other storage solutions
that would mitigate costs and provide better, more robust data
management software than the technology offered through
NetApp and EMC.
