Dell Technologies presents Dell PowerScale (replacing EMC Isilon) as a scale-out NAS solution and server technology that provides the flexibility of a software-defined architecture with accelerated hardware innovations to harness the value of data.
Isilon Systems was acquired by EMC in 2010; some EMC Isilon NAS appliances are still available and supported under the PowerScale brand.
EMC Isilon Scale-Out NAS is well suited for larger files (greater the 128 Kb) and where you need to have everything in one common name space. Where it is less appropriate is for many small files (millions of files less than 128 Kb in size) - this causes the protection level to becoming mirroring, which will cost more space.
Quantum StorNext is well suited in environments with a high, fast paced workflow, with lots and lots of client systems connected, all needing to share the same assets, where you cannot have one moment of downtime. With the pace nowadays that clients expect work to get done, as opposed to 10 years or so ago (pre-iPhone social media instant instant gotta have it right away days), even downtime of 30 minutes can back up your whole workflow. As they say, time is money and Quantum StorNext almost certainly guarantees you have little to no downtime at all. It just works, silently, quietly in the background, making sure everyone is performing at 100% of their potential or more.
Quantum StorNext just works and by that, I mean it just works flawlessly in the background, while your artists are doing their creative work on jobs with clients. Technical issues and hold-ups should never get in the way of the creative process.
There is a lot of flexibility with StorNext and options available in software and hardware, to customize the best solution for your workflow.
Great customer support and response times when things do need supporting, whether there is an issue with a piece of hardware (i.e. battery backup to a controller unit that needs replacing). Quantum along with our local support vendor are fast to respond.
Some upgrades require the entire cluster to be rebooted simultaneously. In this day and age, that should not be necessary. This is my biggest disappointment with Isilon to date.
When using multiple storage pools you have to be very careful with your capacity management. Filling up one pool can cause an overflow of data to a pool that is less performance driven. Do not underestimate your capacities or you will find yourself in a tight spot.
Block size is almost always an issue with Isilon. It does not handle all types of data well. In many cases PACS and VNA data is best to be stored on a different storage platform that will utilize the capacity more efficiently that Isilon is capable of.
Deduplication seems to be less efficient on Isilon than on other platforms for similar types of data.
Price. Obviously, when you are at the level of performance that is needed for our work, Quantum can only go so low as a company on cost, to give their customers a blockbuster deal. But any possible discount here and there helps, and Quantum does their best to lower it as low as possible with bundles and pricing deals. By no means is price a deterring factor, for if you are playing at this level (Ferrari vs Camaro), you know it's going to expensive, but it's a solid investment if you want the reliability and performance. And it's actually cheaper when you compare it to other competitors, along with upgrade paths down the road that will cost you less.
Raw disk space vs. logical disk space ratio was significantly better on the Isilon. Fast cache using SSD drives for faster searching is available on the Isilon but not available on the Overland solution. Isilon solution included faster backend switching between nodes.
Our first shared storage was from Facilis. This is a great company, with great hardware and software, of which we use in our NYC office. At the time, it did what we needed it to do and performed smoothly. But then our workflow expanded dramatically and needed to look for the level of SANs in the Quantum range. We passed our Facilis along to the NYC office and ended up getting an Active Storage SAN, which ran on StorNext. That company unfortunately went out of business a few years back (they are back in business within the last year, but I think Chinese owned), so we looked into getting a fully integrated all-in-one Quantum system that included its branded storage and MDCs to work with StorNext.
Quantum StorNext has allowed us to not only perform at a higher level, but greatly expand how many client systems are connected to the SAN. Prior to Quantum, our old SAN could barely handle the workload of half the client systems we have now. So for ROI, I'm not involved with the actual numbers, but I know our work with clients has expanded ten fold and there is no sign of it slowing down.
Confidence and my time not wasted, working with the support vendors to solve a problem. My time is then spent on other areas and projects in the company, not on phone calls and emails.
