Watch the On Demand Webinar “New Use Cases For Server Side Flash”
Maintaining storage performance is something IT has to do and there are a lot of ways to do it. Some are easy, some are complicated, some are affordable, some not so much. But just like most decisions that IT makes there isn’t a ‘one best way’ to solve performance problems. Flash is usually part of that solution but there are many ways to implement these high performance storage devices.
IT needs options. One of those is using caching software that leverages flash in the application server. In fact, server-side flash caching is one of the most affordable, least disruptive and most impactful solutions available. Here are ten reasons why it should be considered first.
Easy to deploy
Server-side flash only impacts one server, not the entire SAN and caching doesn’t require any data migration, data is moved into the cache automatically.
Buying a single SSD for an application server requires much less flash capacity than upgrading a shared storage array.
Some server-side flash caching solutions can leverage several form-factors from many different vendors, meaning no vendor lock-in and a lower cost per GB.
Local storage performance
Using PCIe, SATA or SAS SSDs puts this high-performance storage area closest to the application and the CPU that’s ultimately going to use it. There’s no network latency like there is with a SAN.
PCIe and memory bus performance
Besides taking network latency out of the equation, server-side flash can leverage the speed of the PCIe bus and even the memory bus for the lowest possible storage latency.
Easier to cost justify
Buying flash for each server is an incremental purchase that can be small enough to be made by the server or application team, not a system-level upgrade that requires capital budgeting.
Server-side caching is an automated process, one that typically requires less administration than tiering solutions and doesn’t add to SAN management overhead.
Caching doesn’t require the redundancy of tiering and as a result, typically requires less flash capacity, making it a more efficient solution.
Improved SAN performance
Server-side flash caching reduces the load on shared storage. Some applications see as much as a 90% reduction in SAN traffic, which means that much more resources for other servers and applications.
Improved VM density
The added performance of local flash can immediately boost the number of VMs that each host can support.
