Consider the electrical system of a house built in the 1970s. The wiring and panel may be perfectly good, but the number of available outlets no longer meets the needs of today’s households. And there are only so many outlet splitters you can add before running into trouble. Similarly, your business’ flash storage still works very well for the needs you initially purchased it for, but it can’t support the new technologies that promise to take your company to the next level.
Why? To use technical terms, the protocol is the issue. But to put it simply, it’s a communication problem. Legacy storage solutions are not able to exploit new technology to its full potential. This problem leads to lower performance and higher latencies. Ultimately, the result is lost time, lost money and a major obstacle to new technology integration.
Introducing non-volatile memory express
Fortunately, a new communication standard called non-volatile memory express—or NVMe—has solved the issue, allowing flash memory systems to finally live up to their full potential. While this innovation is already more than five years old, the recent rise in emerging technologies has pushed NVMe to the fore. Once a “nice to have,” NVMe is now a must for any business that wants to do more with its data.
NVMe as a storage protocol is designed from the ground up to work with non-volatile memory (NVM), including the current NAND flash technology and next-generation NVM technologies. As such, it does not have the same limitations as storage protocols designed for hard disk drives.
There are several performance vectors that NVMe addresses, including bandwidth, IOPs, and latency. NVMe is a completely new architecture for storage, from the software stack to the hardware devices and systems.
Now that we’ve established the need, let’s address the issue of cost. It’s true that NVMe systems have a higher cost per gigabyte than their counterparts using the legacy protocol, but since they are substantially more efficient, they actually have a lower cost per IOPS. Better performance drives the total cost of ownership down because you can do more with less. And importantly, doing more with your data is the precursor to cost savings and business growth.
Choosing the right Flash Storage system for you
Today, most leading IT suppliers offer Flash Storage solutions backed by NVMe technology. With such a wide selection of products to choose from, it can be hard to know what’s right for your business. When exploring Flash Storage solutions, some of the factors to consider include:
- System size and speed
- Compatibility with existing storage
- Non-disruptive migration to minimize downtime
- Disaster recovery
- Support service quality
R2i helps firms assess their Flash Storage needs and select the right products to support their development. Typically, we recommend IBM Storwize V7000, FlashSystem 9100 and FlashSystem 900 because these are proven, award-winning solutions that can be used separately or as a customized cluster. And since they’re compatible with other brands of storage devices, businesses can build on what they already own.
