Upgrading to Navisphere Manager

To install the enabler is pretty easy.

I'd recommend to first upgrade to the latest flare version (02.23.050.5.703 off my head). This will take a reboot of the storage processor, so in your case (with a single storage processor) this means all connected servers will need to come down prior to this upgrade. After that you install the enabler the exact same way. This will also take a reboot, so it's probably easier to do these 2 back to back.

As far as I know you can use ITA to monitor, but not manage the array though. So you can look at it, get alerts (SNMP I think), but not create virtual disks or so.

The full Navisphere Manager adds support to purchase and install some other software options from EMC like Mirrorview, Analyzer, SANcopy and full snapview capabilities.

I believe it also adds support for striping MetaLUNs instead of just concatenation.

With a single storage processor AX4-5, I'm not sure I'd pay for a Navisphere Manager upgrade just so I can monitor the array using ITA, but maybe for you it's worth the price.

Thanks, I meant to say monitor not manage with ITA. I've already got alerts getting sent to our SMTP server so it was just a nice have.

 

The main reason for the upgrade was so that I could use Navi Analyser to view any potential IO bottlenecks. I've not got any production servers quite yet (until I get 2SP's), so it's mabey one for the future.

 

Last time I used Navisphere manager a few years back I think Analyser was bundled without any additional cost, is this still the case? - or has it always been a seperate licence?

 

It's always been a separate license unless you bought the Navisphere Enterprise package if I remember correctly.

A single storage processor AX4-5 doesn't have write cache.

Why bother worrying about performance bottlenecks if you have a non-redundant/no-writecache system?
