Overview and Benefits

HP Storage. Works Enterprise File Services Clustered Gateway Delivering high performance file serving for the Enterprise Client LAN Client Scalability and performance Linear scalability up to 16 nodes • 16 TB file systems – 1000’s of TB total storage • Write throughput approaching 2. 5 GB/s Availability • • HP Clustered File System Fully transparent failover – preserving client state information Storage Utilization SAN Fabric • • Create a single pool of storage Virtualization across heterogeneous storage Manageability • • • Manage the cluster from anywhere Utilize standard HP management tools Standard OS integrates into data center Value • Animated Slide • Industry leading price performance Industry standard components

HP Clustered Gateway: Architecture Overview • Multiple Windows 2003 or Linux servers can form a single logical Windows NAS Cluster – like a large virtual server • All file servers can cache and serve all files – no hotspot problem • Clients are load-balanced across all file servers • HP Clustered Gateway is fault tolerant • HP Clustered Gateway is operationally efficient: − One set of files to backup − Backup up the shared storage, not each server − One copy of files can be shared across all servers (no replication required) Client LAN HP Clustered File System SAN Fabric Client

Leverage Your Storage Investment Build a file serving solution that scales as your storage scales. • HP Storage • Fully compatible with HP’s complete line of SAN storage including MSA, EVA and XP • EVA Snapshot capability integrated (3. X products) • Ideal File Serving solution for HP arrays • Third Party Storage • Partial list of storage arrays includes EMC CLARii. ON, HDS Thunder and Lightning, Data. Direct Networks, etc.

Flexibility with Scalable NAS Clusters • Can add servers, storage as needed − Take advantage of improving server speeds in mass market − Incrementally upgrade CPU capacity on as-needed basis − Roll out new cluster servers with zero cluster downtime • Can mix NAS and direct SAN access − Servers in cluster are standard Intel machines − Run applications on the cluster for direct-to-SAN I/O throughput − Support simultaneous CIFS, NFS and direct-from-cluster access to data • Can use standard administrative tools − Use standard backup products on cluster servers—no need for custom agent support • Backup Server Can customize servers for specific tasks − Dedicate server to backup, if desired; no impact on NAS servers • NFS Servers NFS Cluster with Dedicated Backup Server Can save backup license costs—one server backs up whole cluster!

Unlimited Backup Windows • Any One server can back up all file systems – even in a 16 node cluster • Backup the shared cluster file systems, not the nodes – fewer admin jobs • Step 1: Snapshot in Storage array • Step 2: Mount snapshot in cluster • Step 3: Backup snapshot • Easily automated • Users have continuous uninterrupted access to live data at all times • Only one copy of backup software license required All servers backed up centrally Recover to any other server • Use standard administrative tools and backup products (eg, Veritas)

Architectures: Distributed File Systems What CGW is NOT Director Meta Data Node(s) Node Storage • • • Client Network Director Meta Data Node(s) Node Storage Each node has a piece of the overall file system Hot spots are a typical problem Requires redundant fail-over hardware pairs Node Storage • • Node Storage HP SFS adds striping for performance Net. App Spinnaker is one of these

Architectures: Clustered (SAN) File Systems What CGW IS: Client Network Node Shared Storage SAN • • Each node attached to the same shared (SAN) storage HP Clustered Gateway fall into this catagory Node

Architectures: “Shared Nothing” Symmetrical /Dir 1/File 1 /Dir 2/File 2 /Dir 3/File 3 Node Node /Dir 2/File 2 /Dir 3/File 3 Node /Dir 1/File 1 /Dir 2/File 2 /Dir 3/File 3 • All Nodes see the same storage • Any file can be presented by any client concurrently • Each node has its own storage • On failover, storage is moved to another node • Files are served only by a single node (hot spots)

HP Clustered Gateway Symmetrical File Systems Animated Slide Client Network CGW Node Storage CGW Node Storage SAN • • Each node sees the complete file system Any node can fail over for any other • More efficient use of node hardware • • Eliminates hot spot & load balancing issues Distributed Lock Manager – scales with cluster

HP Storage.
