Dell PowerFlex vs. Dell PowerScale

Definitely would recommend this unit or this family of units into most peoples organizations. Especially if you're starting fresh with a whole dedicated SAN and dont have to move a ton of data over to these (though that is possible, it is very messy). If you're moving from existing storage, then you will have to be prepared for some sore spots!

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.

• Gets all your (SAN) ducks in a row, and makes it easy with a single pane of glass
• The usual good dell support if you're paying for the right support level
• It can get expensive with options added but base price is pretty competitive

• Costs are high, especially when having to replace multiple old SAN's with the one type
• There is alot of down time when you have to push updates out to the units
• Not sure we still have the full hang of all the functions as there's some pretty deep functions that are not explained well

• 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.

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.

• Money saved in having a bunch of other competing storage units
• All kinds of time saved for our admins that have to deal with storage
• The units look good and give you that futurey data center vibe!
