Sorry for my ignorance here! I have never used SMVI (as I am sure you can tell)... As you are using SMVI to snap and replicate (using snapmirror) from the primary site to the DR site, does SMVI not need to know about the DR site and hence need licensing there? Or does it not work like this..? Also, does SMVI have the ability to clone (Flexclone) LUNs / NFS which were replicated to the DR array, mount these to the ESX servers and register the VMs? Or do I need SRM for this?

nsitps1976 · ‎2010-10-01

I will have 2 controllers at the primary site and 1 controller at the DR site. Do I need to license the controller for SMVI at the DR site if I am only doing single direction replication (to the DR site)? (I know I need snapmirror for all controllers) If you purchase SMVI for the controllers (not ESX hosts) where do you apply the license if not on the controllers? Within the SMVI GUI? Can I get away with FlexClone at the DR site only?

Still can't see it! Can anyone just explain what is needed for my situation on this thread please?

nsitps1976 · ‎2010-09-30

for some reason I cant access that thread - Access denied! can you copy and paste for me?

If I have three ESX hosts and a FAS2040 (dual) at a primary site and two ESX hosts and a FAS2040 (single) at a DR site what SMVI licensing do I require? I will also be using snapmirror integrated with SMVI for replicating VMs from primary to DR and I wont be running any VMs that require protection at the DR site....

TR-3438 is very good, thanks for pointing me to this. So can you take snapshots if you do not define a snap reserve on the parent volume?

nsitps1976 · ‎2010-09-24

So with lun's is it best to not have a reserve set on the parent volume and instead us FR? --- This would make it easier to understand.. If I can have your best practice that would be good? - Also is it different if you want thin provisioning?

nsitps1976 · ‎2010-09-24

Ok, so what is the point in having a snapshot reserve limit then? Also, why is this different from a NAS volume?

nsitps1976 · ‎2010-09-24

I know this topic as been discussed my times and I have seen the many blogs etc on this, however, if someone can answer the following this would really help me understand this..... With a volume to be used for a NAS environment we only have the snapshot reserve, in which locked blocks consume space until the reserve is full – So why with a volume to be used in a SAN do we have both the snapshot reserve and the fractional reserve???

nsitps1976 · ‎2010-09-13

thanks, makes sence now.

nsitps1976 · ‎2010-09-13

Thanks - I dont have access to this part of NOW, what is the name of the document so I can try and get it else where?

nsitps1976 · ‎2010-09-13

Ok, I will trust your knowledge... Just out of curiosity, at what model level do the internal controllers need to be externally connected?

nsitps1976 · ‎2010-09-13

Defiantly the HA connection – Page 25 of the DOT8.0 7-Mode High Availability Configuration Guide – See below: Note: In the case of systems with two controller modules in a single chassis (except the 31xx systems), both nodes of the HA pair are located in the same chassis and have an internal interconnect.

nsitps1976 · ‎2010-09-13

Please could someone explain how the two controllers within the same chassis (3140) would be connected togther to provide a HA pair? - I have read in the "haconfig guide" that most systems with two controllers in the same chassis are connected via an internal interconnect, except the 31xx....

nsitps1976 · ‎2010-09-10

See the DS4243 Installation and Service Guide - It mentions software based disk ownership on page 4 (also see notes below) - Does this help answer the question????

nsitps1976 · ‎2010-09-10

I have been informed that if you have a 3140 dual and you want to use a DS4243 shelf you will need two shelfs (rather than one)? Is this correct and if so does this apply to the 2040 dual also?

nsitps1976 · ‎2010-09-10

Thanks - Does each controller also have its own root vol? - Also, with a dual controller system (2040C) can I have disks in the head and disks in a single DS4243? (I have heard you may need two DS units with a dual controller array???).

nsitps1976 · ‎2010-09-09

If you have a dual controller system do you need to split the disks into two aggrs, one per controller? - Does all I/O too an aggr go though a single controller, hence split the storage for load balancing?

nsitps1976 · ‎2010-09-09

Would this mean I would need to increase the size of the flexvol containing the lun prior to running the clone?

nsitps1976 · ‎2010-09-08

Thanx everyone - One last thing... If you do use lun clone to clone and access a snapshot, should the clone be located in it's own temporary flexvol until you are finished with it?

nsitps1976 · ‎2010-09-07

So you can clone a lun without flexvol? This would require 100% of the base lun size? In this design we would not be using any snapmanager products, only the built-in snapshot mechanism (I know this cash consistent only!!) - Can anyone help answer the question "can you clone a snapshot of a lun without snaprestore"?

nsitps1976 · ‎2010-09-07

This would require FlexClone to clone the Snapshot - Is there no other way of accessing the Snapshot and access the data (read/write)?

nsitps1976 · ‎2010-09-07

What is the process of accessing volume snapshots in a read and write fashion to recover data if you do not have a SnapRestore license? Example: A lun containing VMs is snapped a few times per day, one of the VMs is destroyed by a virus. To recover the VM can one of the snapshots be mounted and accessed so the VM can be storage vmotioed from the snapshot back to the original lun. Is this possible without snaprestore????

nsitps1976 · ‎2010-09-06

thanks again

nsitps1976 · ‎2010-09-06

Hi Bossman - If I wanted to clone replicated volumes at the DR site (testing etc) do I only need to license flexclone at the DR site and not the Primary site?
