CTERA Edge X Series (Cloud Storage Gateways) vs. Dell PowerScale

This is all about the selling you a "Device" and prices vary greatly between resellers. The devices work well, but the pure cloud solutions need a lot of work.

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.

• SQL Backups just don't work reliably. For us, we lost all of our SQL data backed up through the CTERA Application process. Although the logs indicated a success, that was really not the case. This came close to putting us out of business. Luckily I had taken a genuine SQL backup to a folder. Unfortunately it was a month old. We had to pick-up the pieces from there.
• Don't use it for file sync and share. There are better products out there i.e. anchorworks.com
• Support sucks. Good luck with response time and answers that are inconsistent between team members. For example I had to rebuild a VM from scratch. When I re-installed the CTERA client It obviously thought I was adding another device. When I inquired to tech support, one member said "copy the old Data folder" (I still had the old VHD. That did not work). The other directed me to the correct spot to just change the associated folder. The turn-around time was over 24 hours for this simple fix.
• Documentation, plenty of fodder but no real tech there.

• 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.

Unfortunately CTERA does not stack up well if you want a pure cloud BDR. I have use iDrive and Asigra. iDrive has similar support and SQL backup issues. Asigra can vary widely in support and price, but the software is solid.

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.

• NONE, it about put us out of business

• 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
