As prices for flash storage have declined, their use in virtualized data centers as a technology to improve performance has increased. The varying I/O pattern of a server hosting multiple workloads can create a problem for traditional spinning hard disks – sometimes known as the I/O blender effect. But, random I/O is no problem for flash.
Flash and solid-state drives can dramatically improve IOPS in some scenarios and the number of flash-only arrays is ever growing. And, newer software products designed for virtual infrastructures, such as PernixData's FVP and VMware's VSAN are expanding the use cases for flash. But, it can be difficult to know when your workloads can benefit most from flash and what form factors will give you the biggest bang for your buck. Here are five quick links to help you understand how flash technology is affecting virtualized data centers and how you can use it to accelerate your VMs.
What you need to know about flash
Flash and SSD storage has several benefits for virtualized data centers, but there are also a handful of reasons why you shouldn't jump head-first into a flash purchase. Before you buy, find out how flash can fit into your data center.
Why you should invest in flash today
Using flash and SSD storage is one of the surest ways to improve IOPS and VM performance. With more options – at lower prices – than ever before, find out why our Advisory Board experts say now is the time to invest.
Making the most of your flash investment
There's no doubt that flash can improve VM performance, but in order to take full advantage of your investment, you have to understand where it will do the most good. This article can help you evaluate the pros and cons of server-side flash, hybrid and all-flash arrays.
The implications of local flash
One of the most popular – and efficient – uses of flash in virtualized data centers is as a caching layer. By storing frequently accessed data on a local cache, flash can improve performance by reducing network traffic and latency.
How all-flash arrays are changing the game
Flash has many implications for data centers, but an all-flash array is among the most disruptive. All-flash arrays can dramatically improve performance, but they are costly. Find out why all-flash arrays are here to stay and why they should factor into your next storage purchasing decision.
