Figure 28 – SANtinel software uses pre-defined zones to protect data from unauthorized access.

WWN may only be assigned to a single HSD on each Fibre Channel port. SANtinel software may be used to authorize multiple hosts to access a

particular HSD. SANtinel software may be further used to permit or deny a particular host to access individual LUNs within the HSD, based upon the WWN of the host.

SANtinel software may be used to create up to 128 HSDs per physical Fibre Channel port. Each HSD may contain up to 256 LUNs, with the maximum number of LUNs contained within all HSDs on a given Fibre Channel port reaching 512.

7. Hitachi Virtual LUN and LUN Expansion Software

Virtual LUN software allows administrators to convert fixed-size volumes into several smaller, variable custom-sized volumes. Using the Resource Manager software, users can configure a specific number of megabytes to each custom logical volume image LUN. Virtual LUN software improves data access performance by reducing logical-device contention as well as host I/O-queue times, which can occur when several frequently accessed files are located on a single volume. Multiple LUN types can be configured within each RAID group. Virtual LUN software enables administrators to more fully utilize the physical storage capacity of the Hitachi Freedom Storage systems, while reducing the amount of administrative effort required to balance I/O workloads.

When Virtual LUN software is used in conjunction with FlashAccess software, the user can achieve even better data access performance than when either Virtual LUN software or FlashAccess software is used alone.

The LUN Expansion Manager allows administrators to create virtual LUNs that are larger by expanding the size of a selected LUN. The maximum size is 2TB.

8.Hitachi FlashAccess™ Software Allows Data to be “Locked and Unlocked” in Cache On-the-fly

The Hitachi FlashAccess software utility allows users to dynamically “lock” and “unlock” data into cache in real time. Read and write functions are then
