Likelihood to Recommend

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.

It's not appropriate for storage workloads that need replication to another site, for instance, disaster recovery.It's also not appropriate for storage processes that rely on cloning and snapshot capability, for instance, database server volume cloning for refreshing data between application environments.

Pros

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.

  • Supports CIFS, NFS, and S3 for storage options.
  • Top level folder quotas for CIFS helps keep usage under control.
  • For basically secondary storage, it's very fast.

Cons

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.

  • The user interface is a little clunky.
  • Monitoring is a challenge - The flash array does send disk space alerts but proactive system monitoring is lacking.

Without exception, the contacts with support have been quick and extremely knowledgeable. I do not fear getting an underqualified engineer to assess or work on my arrays. In addition to this support structure, the sales engineers are top notch as well.

Alternatives Considered

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.

Pure is easiest to install and administer making it a perfect fit for our EDA scratch environment. Pure lacks mixed mode support which forces Qualcomm to use NetApp or Isilon for any SMB environments.

  • fewer people to administer the systems, as it's easier to use and easy to teach how to use.
  • less space in the rack -- a better density of equipment
  • Users are much happier with the performance of their systems.
