Direct-attachment

In a direct-attached configuration, one or more hosts are directly connected to the controllers.

The Cluster Network

This is used for traffic that is going between the nodes themselves, such as system information that is being replicated between the nodes. Also, if incoming client data traffic hits a network port on a different controller than the one which owns the disks, that traffic will also go over the cluster network.

Adding more FC initiators on host will not solve this bottle-neck situation, we can try to increase the queue depth but we need the number of hosts and the number of target ports to calculate it correctly.

We need to add more FC target ports on our storage to keep the load balanced and distributed You can find more information on this link

Installing VSC is the best practice recommended by Netapp when you use VMware and this is an environment with only Ethernet switch, so ISCSI licenses are needed to present LUNs to the Virtual environment.

Automatic host-side space management with SCSI thinly provisioned LUNs If your host supports SCSI thin provisioning, you can enable the space-allocation option in ONTAP to turn on automatic host-side space management.

Moving a Volume will only work if you are doing it within the same SVM Volume Reallocation is used when you add new disks to an aggregate and you need to redistribute the data Aggregate Reallocation can be used only when you are moving data from an AFF filer to another AFF filer Rehosting a volume from one SVM to another SVM Volume rehost enables you to reassign NAS or SAN volumes from one storage virtual machine (SVM, formerly known as Vserver) to another SVM without requiring a SnapMirror copy. The volume rehost procedures depend upon the protocol type and the volume type. Volume rehost is a disruptive operation for data access and volume management.
