Dell EMC SC Series

Dell Compellent has a decent portfolio of products for varying sizes of business. Their licensing model is suited for those not wanting total a la carte fare, and administration is intuitive as compared to other storage arrays. This combined with Co-Pilot support gives Dell a good presence in a vast number of scenarios where networked storage is required over a DAS solution. It's only fallback is its own NAS solution, which itself may be better suited to smaller environments

EMC Isilon Scale-Out NAS

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.

Pros

Dell EMC SC Series

  • Dell EMC SC Series (Compellent) does work well most of the time, but when there are massive i/o issues such as snapshot consolidation, it seems to function poorly.
  • Dell EMC SC Series (Compellent) is an easy to use array. Simple to configure volumes, add servers, and adjust policies.
  • The updates seem to be easily resolvable, with very little to no issues coming from any problematic update paths.

EMC Isilon Scale-Out NAS

  • Isilon NAS scales up well and node replacement is easy. You can replace a node by simply adding a new node and evacuating the node that you want to retire.
  • If the file system layout is designed and executed properly it is an excellent SMB platform with the flexibility to adjust to different share structures. Make sure to take the time to fully understand the AD integration and best practices for share and NTFS permissions management.
  • Node redundancy allows for most upgrades to be installed and applied with rolling node reboots allowing the file systems to stay available throughout the process of applying updates.
  • Native replication is excellent. Jobs complete quickly and we rarely have any replication issues with our Isilon to Isilon replication.

Cons

Dell EMC SC Series

  • Reliability. We had several times where VMFS luns would become corrupted and we'd have to move all VM's off to other storage
  • Performance. 1g iSCSI performance was abysmal (although the unit we used was an older device)
  • Management and Monitoring. Both management and monitoring are pretty primitive. We were never able to integrate monitoring into Nagios.

EMC Isilon Scale-Out NAS

  • OneFS block size is somewhere around 128kb stripe unit while most of our tif image files are around 50kb so our logical vs. physical storage is far apart. This caused extra capacity to be needed. I'd like to see the minimum block size to be smaller or initially adjustable depending on user data type.
  • This may just be a training issue, but it's confusing looking at "free" space available when I have a file share mapped to Windows vs. what OneFS states for available free space as they do not match.
  • We noticed that after adding a new node to an existing cluster in production that we had to adjust the networking config in OneFS to allow for another dhcp address so the new node could get an IP address. Normally this wouldn't matter, but it did have a nasty side effect where the SMB service failed after changing the network config which caused a system wide outage since we mostly use SMB protocol. Once the SMB service was restarted via ssh, we were back in business and it was working again.

Dell EMC SC Series 5.0
Based on 1 answer
This is not solely based on the support engineers themselves but more so that the logging and gotcha's that their array has. There have been multiple times where logs are pulled, but the folder is not large enough, and it crashes the array. Other times there are certain aspects that support either does not know of or isn't knowledgable about how to look at particular issues that could be causing problems.

Alternatives Considered

Dell EMC SC Series

We initially used EqualLogic, however we found the Compellent to scale better, do more, and cost nearly the same. Their approach to storage technology was very innovative and seemed to be the most comprehensive. We needed a SAN that was enterprise class in technology, but at the price of something smaller

EMC Isilon Scale-Out NAS

Isilon is immensely more scalable than Celerra and gave us better control over snapshots and replication. The addition of global deduplication provides a huge space savings benefit as well.

Return on Investment

Dell EMC SC Series

  • The SC9000 has been able to serve our current and futures needs well enough to not need to upgrade anytime soon.

EMC Isilon Scale-Out NAS

  • 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
