IT Brand Pulse recently published a TCO case study on archival storage. In the study, they examine three storage arrays and four software-defined storage (SDS) solutions. Based on their metrics, they found two of the SDS solutions had the lowest TCO and the other two SDS solutions were among the highest, yet at the end of the study, they still conclude that SDS is the future of storage. Putting that minor oddity aside, we agree that SDS has advantages over “traditional” storage array vendors, especially when it comes to not having to pay the “branded storage tax” (a term we’re going to borrow, by the way, thanks guys!). Where we differ from their conclusion, however, is threefold:
1) Fundamentally (and perhaps a little philosophically), all storage is software defined. Some storage software just gets purchased in conjunction with hardware and some gets purchased separately. The former gets lumped in with expensive “proprietary hardware” (typically meaning custom ASICs, FPGAs, etc) and the latter with “commodity server hardware” (i.e. – x86 servers). The former is synonymous with costly traditional storage arrays and the latter with more cost-effective “disaggregated” storage on off-the-shelf servers. Of course, the latter judgment doesn’t ever take into consideration the additional costs of less fault tolerant hardware, dealing with hardware/software/firmware incompatibility issues, having separate hardware and software vendors, and all of the additional costs of supporting and maintaining a disaggregated, multi-vendor solution. Unfortunately, IT Brand Pulse’s Case Study doesn’t take those things into consideration either, but it’s hard to fault them since these things can be difficult to quantify without extensive field study or direct experience…
2) There is a third category of storage: Software-Defined Storage delivered on an x86 hardware platform that is purpose-built for storage. This provides the best of both worlds: the peace of mind and simplicity of “traditional” storage, along with the economics of a disaggregated SDS solution. Think of it as traditional storage without the “branded storage tax” (see, I used the term already!), or “disaggregated SDS” with the look and feel of an actual integrated storage product in conjunction with a far superior support experience to boot. This is where true TCO is found.
3) TrueNAS was not included. Yes, our TrueNAS arrays fall into this third category of storage, and we’ve always been vocal that TrueNAS provides the best value (in both up-front and TCO). Now, thanks to IT Brand Pulse’s research, we have yet another platform to substantiate that claim.
Using the same metrics in their case study, we show the five-year TCO of TrueNAS delivers nearly 25% lower five-year TCO than the lowest solution in the IT Brand Pulse study. Also, an equivalent TrueNAS array provides almost 3x lower TCO than EMC Unity 300, which was the highest five-year TCO in the IT Brand Pulse TCO case study (but, we didn’t need a case study to tell us that, did we?).
Here’s the breakdown of the study with TrueNAS included for comparison:
They normalized up-front storage costs for all storage solutions surveyed at 250TB and then increased capacity 25% every year for a total of five years, ending up at 600TB and deriving overall TCO from those costs. We encourage you to read their case study, of course, but for those that want the nitty-gritty, here’s the table of their results with TrueNAS included:
|IT Brand Pulse TCO Study Findings|
|EMC Unity 300||Disk Array||$330,865|
|Red Hat Enterprise Storage||Software-Defined Storage||$328,847|
|VMware Virtual SAN 6||Software-Defined Storage||$258,151|
|NetApp FAS2554||Disk Array||$211,534|
|IBM v5010||Disk Array||$195,458|
|Scality RING||Software-Defined Storage||$193,384|
|SUSE Enterprise Storage 4||Software-Defined Storage||$149,408|
TrueNAS – Five Year Cost of Ownership: $117,700
TrueNAS provides traditional disk array simplicity and peace of mind at a TCO lower than the lowest SDS solution by a significant margin.
While enterprise customers prefer traditional arrays, they think they have to overpay for them and will therefore save money by using SDS with commercial off-the-shelf servers. With TrueNAS, iXsystems provides the best of both worlds.
So, how do we do it? The secret is in our business and software development models. iXsystems has been a private and profitable business for decades. That means we don’t have VCs breathing down our necks like our more nascent competitors, nor do we have to maintain massive workforces and quarterly earnings for our shareholders like our behemoth, legacy storage counterparts. Developing FreeNAS in our open source community of hundreds of thousands of users gives us the world’s largest QA team and lets us merge only the best and most battle-tested code for our enterprise customers who need the stability, fault tolerance, and performance they expect from our enterprise TrueNAS storage arrays. These factors combined allow us to offer feature-packed storage solutions that provide the most value for your dollar. Again, a big ‘thank you’ to IT Brand Pulse for publishing their study and helping us prove that once again.
