File Serving Needs Scalability High availability High performance file serving needs Industry standard solutions What Customers are saying: Don’t lock me into a proprietary system My storage is rapidly increasing and I have less people I want to leverage my investment – people, equipment, processes, etc. I think I’m paying too much!

Overview and Benefits

HP StorageWorks Enterprise File Services Clustered Gateway Delivering high performance file serving for the Enterprise 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 Client SAN Fabric LAN HP Clustered File System Animated Slide Availability Fully transparent failover – preserving client state information Storage Utilization Create a single pool of storage Virtualization across heterogeneous storage Value Industry leading price performance Industry standard components Manageability Manage the cluster from anywhere Utilize standard HP management tools Standard OS integrates into data center

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 SAN Fabric LAN HP Clustered File System

Leverage Your Storage Investment 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 CLARiiON, HDS Thunder and Lightning, DataDirect Networks, etc. Build a file serving solution that scales as your storage scales.

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 Can customize servers for specific tasks −Dedicate server to backup, if desired; no impact on NAS servers Can save backup license costs—one server backs up whole cluster! NFS Cluster with Dedicated Backup Server NFS Servers Backup Server

Unlimited Backup Windows All servers backed up centrallyRecover to any other server 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 Use standard administrative tools and backup products (eg, Veritas)

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

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

/Dir3/File3 /Dir2/File2 Node /Dir1/File1 Node /Dir1/File1/Dir2/File2/Dir3/File3 /Dir1/File1 /Dir2/File2 /Dir3/File3 /Dir2/File2 /Dir1/File1 /Dir3/File3 /Dir2/File2 /Dir1/File1 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) “Shared Nothing” Symmetrical Architectures : /Dir1/File1/Dir2/File2/Dir3/File3

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