What To Look For in Server Based SSD
As Storage Switzerland discussed in the article “What is Server Based Solid State Caching” there is much to be gained by moving solid state disk (SSD) closer to the application and its processor. The substantial reduction of network I/O and…

What is I/O? – And Why Should You Care?
Recording data to a storage device requires two things, a place to put those bytes and a way to get them written to that device. Capacity is the first thing we think of when talking about a storage system, and…

SSD, Heal Thyself!
It is a well known fact that each write takes a toll on the longevity of flash-based solid state storage (SSS), and that each particular module will eventually fail after reaching its write limit. Depending on the memory type that,…
What is Server Based Solid State Caching?
Thanks to virtualization (server and desktop), cloud computing and big data, many environments are adding capacity to their storage infrastructures to meet performance demand. Essentially they are trying to provide the storage system with access to enough hard disk spindles…

A Little Storage Reclamation Can Dramatically Reduce Storage Expense
Storage capacity requirements are growing in almost every data center causing many IT managers to look for ways to ‘bend the growth curve‘ and keep the IT budget from being consumed by the storage budget. In fact, a small bend…
Tier-1 Storage vs. Tier-2 Storage
It used to be that mid-range data centers could buy a storage system designed for that market and never worry about growing beyond that system’s capacity and performance capabilities. Now however, thanks to server virtualization, “big data” and cloud initiatives,…

Poor Performance Is The Same As Downtime
When the subject of application or data availability comes up in IT meetings the focus of the discussion is what to do when an application fails or the storage system that holds that application’s data fails. Occasionally with a savvy…
When Disaster Strikes, What’s Most Important?
Other than the obvious people issues, when a disaster strikes what’s most important for the data center? Given the time to think about it, most IT managers will answer the question correctly. The most important thing is to restore access…
