Use of Solution

I've used it for two to three years.

Deployment Issues

It had some ridiculous bugs during deployment.

Stability Issues

We have had two stability issues:

  • We had a bad software version that used to randomly crash both nodes in a cluster
  • File system corruption after activating in DR site

Scalability Issues

No issues yet.

Customer Service and Technical Support

Customer Service:

It's at a fair level but has bad documentation.

Technical Support:

It's fair.

Previous Solutions

I previously used Netapp's solution, but this was for a different customer.

Initial Setup

It’s relatively easy to setup and install.

Implementation Team

We used a mix of a vendor team along with an in-house team. The vendor team was good.


We got the equipment via a large storage accusation for almost free so no ROI was needed.

Other Solutions Considered

No, not for this particular customer.

Other Advice

Some bugs cause issues but I love the ASIC architecture behind it. I actually uncovered some hidden ASICs in the hardware. Version 8 features didn’t include in-line de-duplication (it uses an ASIC) which was later uncovered in version 10 or so. It’s nice to find out about added functionality with version upgrades at no extra cost with as little to no performance degradation using this ASIC.
