Migrating from SAN to NAS Isn’t A Hard Decision
Let us help you make the most informed decision before you convert your SAN architecture to NAS.
Keeping Your SAN Just Because You Can
The reasons why you might consider keeping your SAN investment up and running are perfectly rational. To begin with, it was a critical investment at a pivotal point in your company's history. You needed an enterprise-level storage solution and you invested heavily in it. And now, even though new solutions such as ours bring simplicity, performance, and cost efficiencies to the table, who can blame you for wanting to maximize that investment for as long as possible? Your SAN solution is also a familiar solution and one that your IT department has figured out how to maintain in order to keep supporting your organization's storage needs. Further, adding capacity to your existing SAN infrastructure is relatively cheap on the margin. Although this reasoning is logical, there are additional factors to consider when contemplating moving to a high-performance OpenDrives NAS solution. In short, are you keeping your SAN intact just because you can?
Pain with SAN
SAN architectures are more complex and more expensive than NAS architectures. SAN architectures require more non-storage equipment in the overall topology, such as metadata controllers and arrays. You are forced to buy a fibre channel adapter for each client, and, you are also locked into running fiber for performance clients with no copper options available. You even need additional client-side software required to access data. The underlying components to maintain SAN infrastructures are diminishing, e.g. the number of fibre channel switch manufacturers is dwindling. SAN has severe scaling issues and difficult to expand either when adding storage capacity or clients. So what's to love about all that?
Gain with NAS
On the other side of the coin, a NAS solution such as OpenDrives will outperform a SAN architecture. It's a much simpler architectural design, with far less moving parts. With the evolution of Ethernet, connectivity is easier to set up, maintain, and more robust and reliable than block-level access over fiber. The ease of use extends even to the client side, where no special hardware adapters or costly client licenses are necessary. Additionally, OpenDrives NAS solutions are flexible, highly usable with an intuitive console, and are cost effective throughout the entire lifecycle of the solution. So what doesn't sound good about all that?
SAN Conversion, Not if, When
It is generally accepted that SAN is a sunset technology. With NAS, you have choices among storage, switch, and workstation manufacturers given the ubiquity of NAS. With SANs, this simply does not exist. At some point, everyone will make the conversion as SAN components simply won't be available in the market. Every SAN provider of any scale has gone out of business or is having severe financial difficulty. Significant price reductions are 1) an indication of advancements and efficiencies in technology or 2) a rush to dump antiquated inventory. Given that SAN is a 30 to 40-year-old technology, the recent price reductions in the market are indicative of obsolescence.We understand there may be resistance to transition to a faster, more reliable, and more efficient NAS solution if the current workflow is sufficient. However, the market has spoken and delaying the decision is likely to result in unanticipated costs. Many of OpenDrives' customers have made this change and have never looked back.
