How to create aligned partitions in Linux for use with NetApp LUNs, VMDKs, VHDs and other virtual disk containers

Applies to

Data ONTAP 8 7-Mode
Data ONTAP 7 and earlier

Description

As a best practice, NetApp LUNs should always be partitioned with a single primary partition. The partition serves two purposes. It functions as a label for the LUN or virtual disk which helps the operating system identify the contents of the LUN or virtual disk. The partition is also used to align the host's file system with the LUN or virtual disk. Aligning the host file system is necessary to achieve optimal performance of read and write I/Os.

How to enter the filer's CIFS shares in the DFS root tree

Applies to

Data ONTAP 7

Description

Distributed File System for Microsoft Windows NT Server (DFS) allows distributed file systems capabilities on Windows NT Server. A distributed file system provides a single tree structure for multiple shared volumes located on different servers. A user accessing a share using DFS doesn't need to know the name of the server where the share resides.

If a file server goes down, or if you need to move a volume from one server to another, you can do so without informing users of the change. You can increase data availability and transparently distribute load across multiple servers by using duplicate storage points for a single volume.
