Must-know strategies when migrating from spinning disk.
The tipping point has arrived. Large enterprises are planning their next-generation data centers around flash-based storage, and for good reason. Flash arrays provide read and write performance that is orders of magnitude faster than spinning media at a total cost of ownership that is on par with disk and will soon be lower. The benefits not only include improved application performance, but more consistent performance, lower latency, reduced storage footprint, streamlined storage administration, and lower operating costs, which are too beneficial to your business to ignore. That’s why flash is becoming the standard for new storage investments.
For enterprise customers, IDC expects flash to continue to outpace HDD growth, with the expectation that SSD capacity shipped will increase by more than 75 percent year-over-year. One reason for this could be that prices are declining more rapidly than expected. Current research indicates that when considering the total cost of ownership (TCO) over a four year period, flash will become the lowest cost media for almost all storage beginning in 2016. TCO for flash will continue to decline through 2020, providing a return on investment thatspinning disk solutions will not be able to meet.
Yet just two years ago, for many businesses, deploying an all-flash array required justification because of the perceived cost premium. Today, for many data centers, deploying anything other than a flash array for primary storage needs requires the same level of justification. While spinning disk and tape still have a place in today’s data center, and will have for a long time to come for primary workloads, flash arrays have quickly become the default for new storage investments.
