Release 2 of the Vess R2000 Series incorporates principles of unified storage into its core operation in order to
simplify and streamline administration of storage resources. The Vess R2000 supports file-based NAS and block-
based SAN to allow users and applications to access data consolidated on a single device.
This new feature is intended to improve overall performance and allow centralized management of NAS and
SAN resources, however more careful planning of storage environment will be necessary in order to fully utilize
the advantages this system provides. Consideration should be given in particular to how reliability or performance
might be improved or reduced for mission-critical and other applications before allocating NAS or SAN resources.
The main characteristics and advantages of the NAS/SAN unified approach are:
• File-based (NAS) and block-based (SAN) access are consolidated in a single storage system that
supports fibre channel SAN, iSCSI SAN, and NAS using standard file protocols such as CIFS and NFS .
• Storage of file data and block-based I/O (input/output) of enterprise applications function simultaneously.
• Overall hardware costs are reduced since both the SAN and NAS operate in a single system.
• Flexibility for virtual server environments
• Simplified management
