Dell PowerScale vs. Oracle Solaris

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.

It's good for environments that need to operate 24/7 due to its stability, as I mentioned before. It's also very good for enterprise applications that can't afford unscheduled downtime, for truly high-priority environments. I don't think it would be recommended for small companies with people who have no prior knowledge of the tool, as the learning curve is quite steep.

• 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.

You need to take the time to learn it. It is a massive product.

The support teams are well trained and responsive. Patches are rolled out regularly and are easy to deploy and backout.

Stress testing and timing is key. You need test systems that mirror the live environments. User testing must be reflected in peak loads.

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.

We used Windows Server quite a bit because of the ease of use for the team, file sharing, Active Directory, and systems integrated with Windows; learning was easier, and the interface was more user-friendly. On the other hand, Oracle stood out for its stability because we provide services that keep environments up and running 24/7.
