Can volumes etc be added to a vfiler once the vfiler is up and running in production – On P37 of the DOT 7.3 Mutistore Mgmt Guide it states “When resources are being moved, all network connections to the vFiler units are terminated” – This is a worry as I cannot disrupt service if I want to add extra storage etc????? ...

As in my previous post, as I need separation using ipspaces I can only have on vlan per vfiler and this would prevent me from being able to use a separate vlan for snapmirror replication. This leaves me with having to allow all IPs (vif + aliases) through an ACL for snapmirror - Can anyone confirm if I am right or wrong? ... View more

The vfilers will host data that should be securely partitioned and each vfiler will require an ipspace - Also, each vfiler will replicate data through separate network infrastructure and WAN links (once it has routed off the storage infrastructure). With this is mind I can only have one subnet / VLAN (ipspace) so can't separate my replication traffic to a VLAN with a single IP??? Can I? ... View more

So the replication traffic will not have a src IP of the VIF?! The solution you gave will be very confusing to implement as we will also be using mutistore - One VIF (4 x 1Gb links) will have multiple vlans (one per customer / vfiler) and each vlan will have an IP and 3 aliases (for IP load balancing). Are there any other ways we can make sure replication comes from only 1 designated IP? ... View more

I have another question please: I want to ensure that snapmirror replication traffic for each vfiler uses the default gateway for the ipspace in which the vfiler resides – I do not want all customer (vfilers) volume replication to go via the default gateway of vfiler0. Is this possible? ... View more

Thanks again for all this great info. A few other questions if I can: 1 - So all vfiler config is done via the CLI? – What about the VSC 2.0, does this work with vFilers? Can storage etc be monitored from any GUI tools? 2 – Can a volume from within a vfiler be replicated via snapmirror to a none mutistore system? 3 - Why create two VIFs and bind them together rather than one VIF with four physical interfaces and four IP addresses to allow ip hash load balancing? 4 -  Can you point me at some decent documentation / training material? All I can find ONTAP 7.3 Stroage Managment Guide ... View more

Great, thanks. Does this mean you can also have multiple IPs per vFiler for iSCSI / NFS load balancing? Also, in your experience are there any drawbacks or things to be aware of when using multistore? Multiple customers will be hosted on the system running multistore, each in an iSCSI SAN environment, using VMware SRM and Snapmirror replicating to a system which does not utilise mulistore. Any advice you can give would be greatly appreciated as I am a little worried that the introduction of multistore may cause some issues, by that time it may be too late! ... View more

Thanks - what about LUN clones? I also hear these being mentioned ... View more

Great, thanks for your help. Lastly, when you buy and install the hardware are the flexscale options available for configuration immediately? ... View more

So flashcache and PAM II are the same things? An IBM (N Series) disti is stating that Flexscale is no longer used, is this incorrect?  ... View more
