1. Storage Appliance Introduction 11/99

2. Introduction to Storage Appliance • Presentation Overview • The Market Need • Storage Appliance (System Software for Storage Appliance) • Storage Appliance Functions • Based on VERITAS Existing and New Technology • Block Server and File Server Applications • New SAN Protocol • Extending Storage Appliance Architecture

3. Why Centralized Storage? • IDC’s 1997 survey: How much storage capacity can one IT manager support? • Distributed Servers and Storage = 100 GB • Servers and Storage in 1 room = 200 GB • Consolidated Storage Server = 700 GB • Data Growing at 90% per year (See next slide) • Centralizing storage means labor cost cut to 1/7 the labor cost of Distributed Servers and Storage

4. • Voice/data integration • Wireless • Video-on-demand WEB Data Analysis EnterpriseApplications Client/Server Basic Accounting Storage Fuels Applications Storage Capacity 70’s 80’s 90’s 00’s 10’s

5. Customer Examples, Centralized Storage • Silicon Valley Software Company SAP 1998 • Test Deployment 60 GB per server • Final deployment 20 GB per server • Need to re-deploy storage from test environment to final environment • Can we move storage from one facility to another without physical movement of drives? • Can this be done while systems are on-line?

6. Customer Examples, Centralized Storage • Chicago Ad Agency 1997 • Various imaging / productivity applications • SUN, Intel NT, RS/6000, platforms • Desire to manage storage as a centralized pool as needs change • RS/6000 Shrinks as application platform • NT Grows as application platform • Move applications and storage requirements between operating system platforms as needed

7. Why Storage Appliance • Virtualized Storage for a SAN • Create Routes / Virtual Disks (target mode) • Assign / Reassign / Change Size on line • Central Point of Management • Richness of VERITAS Software Functions • Server or Back End software • Volume Manager / File System • Replication / Backup / VCS • Client Software • Volume Manager / File System / VCS

8. Storage Appliance for Blocks or Files Local Area Network Storage Network Disk, RAID, .. One Suite of Software for Storage Management ofSAN (Blocks / Raw Partitions) and NAS (Files) • NAS • CIFS/NFS File Serving /sharing • Remote Mounts / UNIX / NT • SAN • Block Serving across OS Types • Data Required as Blocks (DB, Exchange) • Virtual Disk Manager Flexibility

9. Storage Appliance Functions • Functions • Multi OS Storage access (NT / Various UNIX) • Centralized Data and Management • Manage Change in Capacity (grow/shrink) • Data (RAID) and Path Protection • Backup / Self Archiving Storage / Replication • Data Access Methods • File Serving through NFS /CIFS • Block Serving through SCSI/FC • New File/Volume Protocols as available

10. How do VERITAS Hardware Partners Build It? • Use Inexpensive Open System Hardware • “PC” and SPARC OEM system boards • RAID, drives, NIC cards, HBAs etc . • Use Veritas Software • Existing Vol. Manager / File System / Admin. • New Virtual Disk Server (Target Mode) • Existing Options: Backup, Cluster etc. • Use Commodity or Volume OS • Fast, Lightweight on SPARC or Intel PC • Solaris today, Future: Linux, (someday NT?) • RTOS is NOT a requirement nor desired

11. Network Access (IP) SAN Access (FC) Network Interface Cards Fibre Channel HBAs VIRTUAL DEVICE & Transport SAMBA+ Management interface Java SAMBA Extensions Quick Log Quick I/O VRTS File System VRTS Volume Manager Drivers / Disks /HBAs / RAID Cont . Software Architecture Block Server File Server Add-on STORGAE Applications backup/HSM, etc.. VERITAS Existing VERITAS development OS/Hardware vendor

12. Existing VERITAS Technology • Volume Manager: • Creates pools of storage / Attributes / RAID • Abstracts physical storage configuration • File system • Allocates virtual disks as files • Easily resizable • Provides “SnapShot” Point in Time Feature • Enables BLIB (Block Level Incremental Backup) Feature • Quick I/O • High speed direct access to files • Initially developed for Database operations • Backup, HSM, Replication, etc.

13. New Block Serving Technology • Virtual disk layer • Provides Target Mode Access (Storage Appliance looks like disks to client hosts on the SAN) • Manage all capacity from one disk pool • Grow/Shrink capacity per host (or per host assigned volume) as needed • Presents files as targets on the external SAN • Multiple paths: one file can be presented as ANY number of disks to the external SAN • Interface with HBA is defined and available • OS I/O paths are highly optimized • System page cache interface

15. New Block Serving Technology • Virtual Disk Management interface • Java based (Microsoft Explorer functionality) • Works in conjunction with the Java based administration for Volume Manager and File System • Long term: Work with VERITAS Storage Management GUI Administration integrating VERITAS products • Provides data-centric administration and configuration • PERL, SQL and JVM APIs

21. Storage Routing VCS Block Server Personality Application servers FC FABRIC “Front-end” SAN Storage Appliance Storage Appliance High Availability Storage Appliance Farm “Back-end” SAN Physical storage (disk/arrays, tape libraries, etc)

22. File Server Personality • NFS for UNIX by VxFS with Journal NFS • SAMBA+ supports NT and NT/UNIX Record Locking • Modified SAMBA 2.0.x (back to open source) • integrated with VRTS File System to support coherent oplock model (Optimistic Locks) • performance improvements (eliminate data copying, etc.) • With ACL support, adds NT/UNIX File Locking

23. New SAN Protocol Needed • Existing storage protocols are not optimal in the SAN environment • Network File System (CIFS/NFS) • Runs on top of a networking stack (File Access) • Doesn’t work well for data/block access • SCSI/Fibre Channel • Doesn’t work well for heterogeneous data sharing • Volume and SAN File protocols needed

24. LAN / File Sharing protocols (NFS, CIFS/SMB) SAN File Access NAS FileAccess SAN / File Access prot SAN file access LAN file access Device Interface Volume Manager File System SAN / FC protocol OS driver Available Today Application Server Volume Interface Near Future New SAN File System Protocols /APIs SAN / Volume Accessprot Data Flow File system VOL MGR Standard OS Storage Appliance Device

25. SAN Storage Access Protocol • Merges Block and File access • “Quick I/O for SAN” • Multiple attempts mostly by the hardware storage vendors; • Control of and/or footprint on host is needed • VERITAS is in a unique position to provide BOTH sides of the protocol

26. Extending Storage Appliance Architecture • Release with Volume Manager, File System, and Virtual Disk Manager • Integrate Backup, HSM , Replication, Clusters • Integrate SAN File System as available • Extend the boundaries of the SAN with: • Global Management • Discovery • Agents in Switches, Routers, etc • The SAN is the Computing and Data Fabric
