If my datastore is store in Clustered ONTAP volume(By NFS) or LUN Is any NetApp tool or plug-in can help virtual machine clone more rapider and offload the host cpu loading to ONTAP Controller node? Thanks

Hi, We have NetApp AFF400 at DC site ad NetApp FAS2650 storage at DR site. They are running the same operating system (ONTAP 10.1) Is it possible to configure SRA-based replication with two different model storage at DC & DR? SRM Version 8.5, ONTAP Version 10.1.

Hello Expert, I have a topology-like picture Below: 1. 2 ESXi 2. 2 NX3548 (Active-Standby) 3. NetApp FAS2750 with ONTAP 9.11 4. Using iSCSI Connection with NetApp and ESX. my question is: 1. is it best practice to use vPC, port-channel, and channel-group connection on NX Switch, if I need to set up iSCSI Connection? what are the recommendation and best practices? 2. I have 4 ports of 2 controllers FAS2750, like e0c and e0d, and connected to an NX Switch port using port 7 and port 10, do I need to set up LAG? or just leave it with no LAG so that VMware will arrange or handle it for redundancy and speed performance? because we need to leverage that 4 links active-active. 3. NetApp FAS2750 is the new box, and there is existing FAS2650 with ONTAP 7-mode which will be migrate to the new one. For your information, I see the existing configuration on the 2 switches above, the existing configuration used vPC with port 1 and port 2 that used NetApp FAS2650. Thank you for response. Regards, Syams

Hello, Today's logic with iGroup is way too strict and creates an unwanted situation. As documented in the following KB: VSC and VASA_Provider/Why does Virtual Storage Console (VSC) create "rcu_generated_alua" iGroup and Storage Replication Adapter: What determines if a new initiator group or export policy is created during a failover operation? , we learn a new iGroup gets created if the system doesn't find an equivalent iGroup with all initiators. So far, nothing's wrong but the problem appears when you have an iGroup with all detected initiators but with extra initiators used by your backup system whose requirement is to connect on a LUN to backup or restore. Your only way to back to your original IGroup is to "force" unmap, map the LUN again and rediscover your system storage. It creates a system service disturbance which is a situation no one wants. Now, you add your extra initiators to an automatically created iGroup by either VSC or SRM well next time you do a similar operation like creating a LUN/NFS or failOver, it will try to create a new iGroup or choose an iGroup with exact same list of initiators/export. Would it be possible to switch or leave the operator to decide to use minimal requirements (detected initiators) instead of strict requirements? Regards, Oli

We are on SnapCenter 4.6 currently setting up VMware snapshot protection. I got a few questions wish someone can share your experience. 1. if we take snapshots on datastores, will IOs be hold during snapshot? is there any snapshot technology involved? 2. we have many datastores (around hundred for one folder on same VCenter), should we create single resource group or split to multiple resource groups? We have a resource group with 30 datastores, it took around 15 minutes to complete the snapshot, just wonder if any Array resource (CPU, memory, cache) will be consumed to impact the array performance? 3. is there any easier way to run a VM on demand snapshot instead of create resource group? 4. is there time and space usage difference for an on demand snapshot between a single VM and its datastore? 5. we plan to keep one week datastore snapshots, is that a good approach?
