1 Deploying Scalable Switched NAS Infrastructures in the NFS Environment ) 6, ' < & 2 ) & Vladimir Miloushev Executive VP and CTO Z-force, Inc. vlad@z-force.com October 22-23, 2002

2 RAID Aggregates Block-Level Storage Single Large Expensive Disk RAID ARRAY DISRUPTION RAID Controller + SCSI Disks SCSI Disks

3 File Switch Aggregates File-Level Storage Large Clustered File Servers NAS ARRAY DISRUPTION File Switch + Inexpensive NAS Servers Inexpensive NAS Servers

4 Today NAS is limited to a point solution y Cannot scale non-disruptively for growth ) 6, ' < & 2 ) & y No scalability = manageability problems y Stranded islands of storage y Underutilized NAS file serving capability y Multiple forklift upgrades over time y High-availability solutions are complex & expensive NAS Must Move to Become a Scalable Infrastructure October 22-23, 2002

5 Key Company Facts Founded in late 999 Offices in Laguna Hills and Santa Clara, CA ) 6, ' < & 2 ) & Key technology patent granted by USPTO 2 more patents pending First venture round of $6M Key Investors: Allegis Capital Alloy Ventures Quantum Technology Ventures Rock Creek Capital October 22-23, 2002
