Dell PowerScale vs. Dell VMAX

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.

Dell EMC VMAX All-Flash Storage is a very powerful storage that easily manages huge data transactions with high IO processing speed. This Storage is well suited for critical production environments because response times are much better. This storage enables direct data backup. It's always up and running during updates because it creates a redundant connection from the controller.

• It creates a fully redundant connection from multiple controllers that are always up even during updates.
• Once setup there is little to no adjustments that need to be made to the storage array. All that's needed is volume updates.

• 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.

• Initial configuration are bit difficult need some experience resource to manage it.
• We faced issue with vendor support during major impact.

The best part about this array is that once you have it configured it is pretty much done. There is little to no other configurations to be done other than normal volume adjustments. Support is great as they understand this array very well. The updates are very hands-off and are done solely by support. You contact them and then there are no other changes done on the end-user's side.

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.
