Hello Frank,

Thank you for your reply, a few follow up questions:

  • you keep mentioning "moderate amounts",  what is moderate in your opinion ?  Are you still bound by the same file system size limitations, file system per datamover limitations ...as physical File OE platform ?
  • You listed data services for VMAX , specifically Dynamic Host IO Limits. How does that applied to eNAS ? Are you treating eNAS as another host and can control how much IO it can be allotted ?  I am sure you can't control how much IO is given to individual file systems inside of eNAS
  • What kind of implications/considerations does it present in terms of code upgrades. Can i upgrade eNAS without upgrading Enginuity ?
  • Can eNAS replicate (file system level replication, not SRDF) to another Unified platform ?

Thank you

Dynamox,

When we refer to moderate amounts of file storage we are expecting most customers to start off with < 200TB of usable file capacity and grow to larger amounts overtime. VMAX3 supports up to 768TB of usable file storage capacity with a maximum file system size of 16TB. Note that some customers will elect to support up to 768TBs of file data with VMAX3 at initial deployment. We just do not expect it to be the norm.

Your other questions will be better answered by Paul or Kevin on this panel.

Thanks again for your interest in embedded NAS on VMAX3.

Frank

Hi Dynamox,

The Dynamic Host IO Limits does treat eNAS as another host. You are able to control how much IO can be allotted to the child SGs that are presented which make up the separate NAS storage pools. You are not able to individually control how much IO is given to individual file systems.

eNAS Code upgrades are performed as part of the HYPERMAX OS upgrade. During the upgrade it is asked if you want the Data Movers to be rebooted automatically or manually to have the eNAS Code upgrade take effect.

eNAS can replicate right now using the asynchronous IP based File Replication.

hi ,

Do we have any best practice for getting the FC cabling done on the VMAX3.
