SANPoint Foundation Suite /HA

Provides

Transparent access to shared files Multiple servers can mount and access the same file system

Allows for consolidation of storage resources and greatermanageability

Faster file access (direct access) Eliminates need to go through TCP/IP stack

Enables realistic access times for databases using shared filesystems (as compared to NFS)

Enhanced failover capabilities No need for Volume / File System failover

Quick and controlled application failover (automated in HA-

version only) Enhanced workload management (HA-version)

The Result: Near 24x7 data availability

Discovered Direct I/O

High performance for applications with mixed I/O sizes

For large FS writes, it is much faster to write directly to thedisk

Direct I/O skips the FS cache BUT, for smaller writes, direct I/O is slower!

We developed... Discovered direct i/o

DDI/O looks at the size of each write & gets the best performancefrom each I/O model

Example:

If write is 256KB, uses Direct I/O

Availability & Performance

Dynamic Multi-Pathing (DMP) provides multiple

paths from server to storage

Path load balancing improves I/O bandwidth,spreading I/O across connections

Path failover increases application availability
