Likelihood to Recommend 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.
Read full review The team in charge of implementing Scality has to be full stack in order to guarantee the correct functioning of the entire system. However, you have to think very carefully about the balance between servers and disks, perhaps adopting smaller fully populated servers instead of large semi-populated servers, which would mean that over time our disk updates will not have a fully useful life.

Read full review Cons 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. Read full review The overall packaging is not very good. I think it could be more efficient for installation. There are many components in storage servers. This can generally be complex to understand, you have to be patient. Read full review Usability As an organization, it took us a while to understand the shift from a traditional black box SAN to software-defined storage, but now we are much more certain of what this means. The time invested and the resources were not very high, thanks on the one hand to the technical support and on the other to the coherence and good development of the platform.

Read full review Alternatives Considered 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.
Read full review Due to the nature of our business we require extensive encryption and availability for sensitive customer data. The erasure encoding that Scality provides gives us the assurance that documents are rest are never in a state of being downloaded or available to a casual data thief. This is something that can be found with other vendors but at a fraction of the same cost. Having this kind of performance, availability and redundancy at the cost that Scality provides has made a large difference to our organization.
Read full review Return on Investment Isilon provides very high value for money Matches the performance and storage requirements of the arrays EMC provides very skillful and high response team in case of any issues in isilon Read full review Keeping sensitive customer data secure is a must for our organization and Scality has great features to make this happen. We replaced a single SAN with a Scality ring and found performance to improve as we store more and more customer data. Being able to lose various portions of our Scality ring and allow it to continue to service customers while maintaining high performance has been key to our business. Read full review ScreenShots
