Part 4 of a 5-part series on choosing media for NetApp FAS storage
By Tushar Routh, Sr. Manager, Storage Products, NetApp
In this post I’ll talk about how to take the components I discussed in the previous posts in this series—HDD, SSD, and shelves and interconnects—and put them together into a storage subsystem that will meet your needs now and in the future.
With all the recent attention to flash storage, it would be easy to conclude that HDDs are going to be eclipsed in short order. There are certainly use cases for dedicated all flash arrays, which is why NetApp released the EF540 Flash Array last year, and why we’re busily working on FlashRay, our next generation, scale-out all-flash offering.
However, HDDs—especially in combination with flash—aren’t going away any time soon. The economics of HDD and HDD/flash solutions relative to all-flash still make them the sweet spot for a lot of storage workloads.
Here’s what NetApp suggests:
Here are a few best practices to keep in mind.
A little up front planning—and consideration of the guidelines I’ve outlined here and in previous posts—will go a long way in helping you choose storage that is best suited for your particular workloads and needs. As you’ve no doubt noticed, there are a lot of options to consider: HDD versus SSD, SSD deployed as cache or persistent storage, different capacity points, and so on. Of course, NetApp experts as well as our worldwide network of partners are available to assist you in your decision-making.
You may have also noticed that I haven’t said anything about security up to this point. In the final blog post, I’ll wrap up this series with a discussion of NetApp Storage Encryption.
