Ask the Expert: Meet the EMC Unity Family

Hi Team

We have recently done a deployment for Unity with recoverpoint. The Solve doesn't shows option for Unity with recoverpoint, neither under RecoverPoint and nor under Unity. There are some information provided in Recoverpoint solve but that doesn't seems to be correct. I also looked for RecoverPoint admin guide but again the information is not exact. The screenshots are not for Unity.

Please help.

Hi,

The spec sheet says 1000 but I think it may depend on what form factor you want 2.5 or 3.5 and what type of disks you are using

500 is the current limit - 1000 will be the new limit after an OS upgrade which should be available this quarter

please read the spec sheet carefully when it says "5/1000**" and then below the table

**500 drives available at initial release. 1000 drive support will come within a year.

and no - 2.5 vs. 3.5 inch drives dont make a difference in terms of max number of drives.

Hi Unity Expert, is there a way to manually configure integrated ESRS  VE via command line?

yes - everything that can be configured in the GUI is also available in UEMCLI and via the REST API

the necessary commands are listed in the Unity CLI reference manual available from support.emc.com

To expand on this question... The only time unity should use the battery is in the event of a power loss to both SP's to facilitate de-staging write cache to the non-volatile SSD on the SP and shutting the array down cleanly correct?

Hello Unity Experts,

I understand that a Unity power supply can provide power for both SPs in the event of one power supply failing.  Will it also be able to maintain charging the BBU in the SP with the failed power supply?

Thanks.

Hi Alan,   Yes, a single power supply unit (PSU)  will supply power to the SP and charge the Battery.  One of the benefits of the new Battery-on-Bus architecture is it will charge whenever the PSU output is turned on (and charging is needed).

Thanks

@Rainer_EMC

that is my understanding - I dont see where else we would use it

Hi,

I would like to know how the pool expansion works on Unity, are the LUNs re-balanced across the Raid Groups when we expand the pool?

Thanks

Hi,

I would like to know the HP 3PAR to Unity migration strategy using SAN copy Pull operation? Please share the document, if you have any.

Thanks!!

Hello,

Looking for some help on the Community Edition and trying to regenerate the VASA certificate. It seems that the certificate shows with the Issuer of my PSC FQDN for some reason when it should show as itself for the issuer. Is there a process to regenerate this certificate correctly for the vasa provide URL?? Without being able to do this, I can't register the storage provider or else I'll have to redeploy the VSA again......my guess is that if this can happen on the VSA it can happen on the physical UNITY as well (which isn't as easy to re-deploy )

Thanks!
