HP Dyn Cap Mgmt EVA 4400 Unlimited LTU

[Yaboto]

Hi,

I already have the following licenses: HP Business Copy EVA4400 1TB LTU ; HP CV EVA 4400 Unlimited LTU ; HP Continuous Access EVA 4400 Unlim LTU.
Please tell me the differences between those licenses.
Moreover I have an additional license : HP Dyn Cap Mgmt EVA 4400 Unlimited LTU. This one is very new to me. Please what does it do ?

Regards,
Berag

The last license is a type of thin provisoning. That means your give a lun 100GB but it will use on the storage the space when the it is really going to be used.

Dynamic Capacity is NOT 'thin provisioning'. It is a license to allow the RSM (Replication Solutions Manager) framework to automatically grow Windows 2003/8 virtual disks and expand the file system.

[Peter Mattei]

It allows integration and automation of file system + LUN size growth and shrink.

See the HP StorageWorks Replication Solutions Manager user and admin guides and search for DCM or dynamic capacity management.

thanks Pete I know the link but it is not showing up.

Do you have this paper? if os, can you attach it here?

Thanks
Eric

[Uwe Zessin]

Ah yes, the usual "We're very sorry!" message...

I'll try to attach a copy.

[Eric v Willegen]

Thanks Uwe for the document.

I have to implement this solutions @ a customer soon.

What i'm worried about is that this customer also uses 2 Windows 2008 Clusters. The Release notes of RSM 5.1 are saying that clustering is supported, but i'm wondering how the second node is reacting if you do a resize of the Disk by the RSM-policy?

Anyone has some exeperiences with this?

Any info is welcome!
