Dell PowerScale vs. NetApp AFF A-Series

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.

Easy interface and the accessibility of the features are effective and this solution functionalities on data migration and processing of different from other packages is amazing. NetApp AFF A-Series All Flash Arrays is the most secure platform for easy management of all the business and project data and the capacity planning tools and even the configuration options are the best and easy to use.

• 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.

Incentivized

• Cost is still prohibitive for performance.
• Performance tuning at the Fabric Interconnect level.
• Automation and scripting improvements in the PowerShell module.

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.

I have been an IBM and EMC storage customer. I used EMC CX and VMX series SANs. I have used IBM Shark SANs before that. Much has changed over the years. It is my experience that Netapp has shown a great deal more innovation with large leaps in technology, ease of use and an aggressive progress while the two other vendors that I have experience with are more tied to their legacy technologies.

Incentivized

• 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

• ROI has been tremendous as it has come in handy in all the scenarios we were looking at
• Users and admins both happy with the overall performance and management is happy that they got a good deal from reseller.
