Hi,

When will Recover point be supported in VMAX3 ?

Similarly Please Share the VMAX3 Roadmap for upcoming features , which will help us to position VMAX3 vs VMAX2 .

i have also done the comparison between VMAX10k and VMAX100k , with limited information i have from partner portal.


Thank you.

Welcome to the ECN Ask the Experts event!

This discussion is now officially open for questions. Let's make of this an informative and respectful channel for exchange of information about VMAX 3.

Cheers.

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

I would like to start out with two questions ?

1) How is this different from a gateway model (i used to use CFS-14 with DMX2000 )

2) Why embedded NAS on a VMAX when you have an outstanding platform in Isilon ?

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

With all previous generations of Symmetrix the only way to achieve SRDF consistency across multiple arrays required an external host managing that consistency and the cycle switching. With the Hypervisor built in at the array level now is there the opportunity (now or roadmapped) to allow for that functionality to come back within the array (as long as a VMAX3 is involved) and drop the requirement for an external management host?

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

I've seen several references to the removal of support for metas on VMAX3. How does that work if I have to use SRDF to get data to a VMAX 20K that requires metas?

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

Allen,

Managing SRDF consistency across multiple arrays is still done via a host running SE and the SRDF daemon.  I can't go into roadmap on here but right now that management piece hasn't changed.

On your second question for Metas, all you need to do on the VMAX3 is create a pairing of the same size or bigger on the V3, VMAX systems connecting via SRDF must be running Enginuity 5876.272.177

We have significantly improved SRDF operation under the covers with more concurrency on writes for SRDF/S and Multi Session Cycles on SRDF/A.

For configuring SRDF you should definitely check out Unisphere 8.x the management interface is pretty simple to configure everything for you, on V2 and V3 you can literally just right click and select Protect and SRDF, the wizard will work out the number of hypers and all create a device group for managing.  Worth looking at.

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

Dynamox,

The Internal eNAS Datamover runs on the VMAX3 hypervisor as a VM container, we run a virtual version of the control stations and the datamovers.  We keep the active data movers and control stations on different directors from the standby to ensure the highest availability.  We use an internal cut though driver (essentially the HBA for the datamovers) to access the storage through internal Virtual Front End Ports and we have a secure internal network for all the internal communication and management. 

Provisioning to eNAS is pretty much the same as provisioning to any host,   we have a masking view that is already configured for you when the array is installed.  You can then provision storage to the data movers with or without a Service Level (essentially a target response time) so you get all the functionality of a VNX but you get the added benefits of VMAX3 SLO and the robustness of the VMAX hardware platform.

We have a lot of information on the technote

www.emc.com/collateral/technical-documentation/h13904-vmax3-embedded-nas-technical-note.pdf.

The Doc does a much better job on the positioning of the product than I ever could

Re: Ask the Expert: VMAX3 Hypervisor, Embedded NAS Assessment, Local and Remote Replication Strategies

Hi adeelemc,

Thank you for your interesting in VMAX3. Note that this forum is focused on the extensive feature set offered with VMAX3 today; specifically TimeFinder, eNAS, and SRDF.  EMC is continuously evaluating additional features for VMAX3 arrays.

Roadmap discussions have always required specific approvals and local account team involvement.  Please contact your account team for info in future functionality.  They can certainly contact us and product managers outside of the forum if they need assistance.

Thanks!

Mike

Allen,

 

HYPERMAX OS does not support meta devices; however, device pairs between non-meta devices on an array running HYPERMAX OS and a meta device on an array running Enginutiy 5876 are supported. Device pairs between a non-meta device (HYPERMAX OS) and a meta device (Enginutiy 5876) may be either concatenated or striped.

Best Regards,

-Mike
