It could help to add more detail on the networking side. Better integration with RecoveryPoint would be helpful. Support has a lot more access and visibility to things that are happening. If we have more visibility it would help for troubleshooting purposes and allow faster resolutions to issues.

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 Unity

  • Very reliable arrays with a notification system when a disk fails
  • Simple disk provisioning and mapping
  • Easy to upgrade the firmware
  • Fast access with a relatively cheap storage combination of flash and SATA drives
  • integrates with Vmware vcenter

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 Unity

  • Alerting: receiving an alert when an issue occurs. That is good to know. However, if the alert is cleared, or somehow no longer in alarm, no email is received. At times I will receive the email alert on weekends, not knowing if the issue is resolved or not until Monday when I can access the unit. I have learned in most instances, the alert is a false alarm, which could be a problem.
  • The alerting itself is sometimes not clear. For example, it tells me the link is down, we reset the connection, the link is still down, a tech was dispatched, he troubleshot, and finally the alarm cleared. This incident took almost a week. It went back into alarm after he left, then suddenly it cleared on its own.

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's support for the Unity array is normally quite good. However, when there are issues with the reporting and statistics, they often are not responsive.

Alternatives Considered

Dell EMC Unity

We selected the Dell EMC Unity after looking at several other vendor solutions. We were budget conscious and wanted to select a device which would bring known quantities to the table. We were looking for devices which could support flash drives as the read cache for frequently used files but also needed a device to fit within our sizing and budget.

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 Unity

  • ROI on VxBlock is not so good since RCM updates cost a lot.
  • ROI on Unity by itself is good, however.
