Cohesity

Cohesity is best suited for a highly virtualized environment, although they do have agents for bare metal. But who runs non-virtualized workloads these days anyhow? Not any organization which would invest in best class backup, anyhow.We find that the search features make file-level restores so much easier -- now a partial filename is all we need to get going, and we can see a file's change history by date so we no longer have to hunt for the last changed version. You will want 10GB network capability for this solution to really shine -- each node has dual SFP+ connections for data.

Dell EMC PowerScale (EMC Isilon)

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

Cohesity

  • Easy to use and setup new backup and restore jobs.
  • Extremely fast recovery time, can spin a VMware backup VM up in well under a minute.
  • Granular recovery search options, easy to find specific files or systems to recover (or SQL DB).

Dell EMC PowerScale (EMC Isilon)

  • 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

Cohesity

  • Replication performance - We needed support to provide some customizations in order to get our replication to work properly to another offsite cluster. We have been told that this issue is fixed in the newest general release.
  • Support - I would characterize the support as very good, but in a few instances I could tell my support agent needed to go higher up his chain to get clarification on features. I believe Cohesity is rapidly growing their support infrastructure as they put more hardware in the field.

Dell EMC PowerScale (EMC Isilon)

  • 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.

The user interface is very intuitive and gives a good overview of the status of your backup jobs. Its a full html5 environment which can be used in very browser and is available on every device through the use of private connections to the office. When going to implement Cohesity it is as easy as putting it in the rack and configuring your network. The environment does the rest. Once configured new nodes can be added by configuring them with the correct network.We use it in a VMware vCenter environment with vCloud Director on top. Since the latest version vCloud Director is an official source for your backups. This means that resoring to vCloud Director is a posibility as well. This makes the multi-tenancy and self service capability for our users an easy to use function. It can be implemented as a plugin within the Cloud portal for users to leverage.The path to vCloud Director support took a while but now that we are there I can give it an 8.

They are always friendly, knowledgeable and helpful. The support is easy to reach and the reaction times are on point. Several times I had called with my system being down and the person who answered the call would require a support rep call me back. Some of these call backs would be 1-2 hours later. When needed, the support will scale up to deliver the right support for the right cases. When asking for detailed information about a problem they always help you to understand the problem and the underlying causes better.

Alternatives Considered

Cohesity

We looked at Veeam and although it's a great product when we priced out the licensing of both primary and disaster datacenters it became much too expensive.Rubrik is a great product and very similar to Cohesity. In the end, Cohesity had a secondary storage play as well as a better UI and better compatibility with lower tier cloud storage. We also like the way Cohesity did protection jobs vs Rubrik's virtual machine centric backup.CommVault is a product we still use today due to its massive features and the ability for bare metal backups. Cohesity does a much better job in the area of UI simplicity, virtual backup ease, and ease of management.

Dell EMC PowerScale (EMC Isilon)

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

Cohesity

  • It has freed up 40 hours a month of our service desk staff since they were able to stop focusing so intently on tape management.
  • We have gained time back on the engineers since they are not working tickets 10 hours a week just on backup issues.

Dell EMC PowerScale (EMC Isilon)

  • 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
