WinQuota can work at any kind of storage, like CAS, SAS or NAS (in case all of
them use NTFS file system and Windows supports these devices). SAS and CAS devices
are supported on the regular basis. But when a NAS device is used, you have two different cases:
In case your NAS have no Windows inside, it should not be shared directly to
network. You'll need W2K or W2K3 host as proxy for NAS access (see clusters section
as an example). In case you'll share your NAS directly without WinQuota inside,
WinQuota will not handle access to your files as you may expect.
- - NAS is not attached directly to network, and all resources are
reflected by separate Windows host via re-sharing mechanism or via DFS.
In this case WinQuota should be installed to this host.
- - NAS is attached directly to network, and uses Windows internally, like
Windows 2003 Appliance Edition. In this case WinQuota can be installed
directly on NAS to manage your quota limits.
WinQuota works in W2K and W2K3 clusters, including support of active/passive nodes, nodes file replication and dedicated storage devices such as NAS/CAS/SAS (see attached storages). The typical and recommended WinQuota approach is demonstrated at the following picture:
You should use WinQuota with failover solutions, HA clusters and other, including cases with active/passive nodes separation (as demonstrated above).
If you are planning to use WinQuota at your cluster, you should need the same amount of WinQuota licenses as you have cluster nodes, including active and passive nodes both.
