Why you use Vservers
Vservers provide data access to clients without regard to physical storage or heterogeneous structure, similar to any storage system. Vservers provide nondisruptive operation, scalability, security and support unified storage.
A Vserver has the following benefits:
•
Nondisruptive operation
Vservers are resilient, and can operate continuously and nondisruptively for as long as they are needed. Vservers help clusters to operate continuously across software and hardware upgrades, addition and removal of nodes, and all administrative operations.
•
Scalability
Vservers support on-demand data throughput and the storage requirements.
•
Security
A Vserver appears as a single independent server, which enables multiple Vservers to coexist while ensuring no data flow between them.
•
Unified Storage
Vservers can serve data concurrently through multiple data access protocols. A Vserver provides file-level data access by using NAS protocols, such as CIFS and NFS, and block-level data access by using SAN protocols, such as iSCSI and FCP. A Vserver can serve data to SAN and NAS clients independently at the same time.
•
Delegation of management
A Vserver can have its own user and administration authentication. Vserver administrators can manage the Vservers that they are authorized to access. However, Vserver administrators have privileges assigned by the cluster administrators.
