2 Next Generation Storage Solutions Improve Operations! Better Backups Fast Recovery Manage Growth Easily Affordable Disaster Tolerance Rapid Server Provisioning A Better Way to Store iscsi The Right Storage Network PeerStorage Architecture Unmatched Scalability Unparalleled Features Enterprise Redundancy 2

3 The IT Challenge IT Manager Business Needs Management More data Reduce costs! Data needs are always growing Backups do not finish on time Restores take too long Not able to spend time on important projects 3

4 IT Best Practice Trend: Consolidation File Servers Backup Servers Application Servers spare spare Logs Logs spare Shares spare spare Stores Stores AD Domain Consolidation = Improved operations More efficient resource utilization Simplified provisioning Fewer points of management High availability Advanced features for improved operations Better backup and restore 4

5 Challenge: Storage Consolidation Has Been Limited Complexity and costs Interoperability issues The result: Islands of storage Mission Critical Applications Business Critical Applications Storage Area Network (SAN) Fibre Channel Logs spare Logs spare spare spare Stores Stores AD Domain 5

7 Understanding iscsi 7

8 iscsi is a Better Network for SANs Bring Ethernet economics to storage Enables low cost of ownership Familiar network technology and management Reduces training & staff costs Proven interoperable transport infrastructure Increase reliability Multiple Layers of Security Built-in to Protocol Protects investment with simplified performance upgrades Transition from 1Gb to 10Gb Ethernet and beyond Scalability over long distance Enables remote data replication and disaster recovery Flexibility, Scalability, Reliability, Performance.. Enterprise Competency 8

9 iscsi: Initiator Choices Choice of software or hardware initiators Software initiators (Line speed operation with under 15% CPU utilization) Hardware initiators provide lower overhead for demanding applications the servers Operating systems supported: Windows NT Windows 2000 Windows XP Windows Server 2003 Linux Solaris NetWare HP-UX IBM AIX Apple OS X Apps & File System Other protocols TCP SCSI iscsi Apps & File System Other protocols TCP SCSI iscsi Apps & File System SCSI iscsi TCP IP IP IP Network Hardware Network Hardware Network Hardware NIC Card TOE Card iscsi HBA Card Processed in the Network Card Processed in the Server 9

13 What about the Storage Arrays? 13

14 PeerStorage Architecture Delivers Automatic Storage Simplifies setup and upgrades No software on hosts All features work with all operating systems Storage is qualified / certified on major operating systems Provides key advanced features Always included! High availability Everything is redundant Point in time copies Data transport Disaster recovery Grows on demand Shifts operational burden to the storage devices Maintains single point of management regardless of scale Dramatically lowers administrative overhead Optimizes utilization of assets automatically No hot spots, or cold spots - All devices are evenly loaded Automatically adapts to workload changes Network is balanced 14

15 PeerStorage Array: High Performance / High Availability Enterprise-Class System Fully-redundant hardware (fans, power, controller, disks, network) Hot-swappable hardware 2GB battery backed mirrored memory Three 1Gb Network Interfaces (copper and optical) Serial ATA Disks 10,000 or 7,200 RPM Excellent Performance 300 MB/sec sustained per array 50,000 ios/sec per array Supports RAID 10 and RAID 50 Scales automatically (PeerStorage Intelligence) Qualified Platforms 15

16 PeerStorage Arrays Automatic Scaling Backup Servers Application/Web Servers File Servers Exchange Server SQL Server Domain Server Active Directory Server Switched Gb Ethernet Multiple storage systems join to automate performance and distribute work load Free Space Shares Shares Shares Backups Backups SQL AD / Dom Manage as a single system, even as it grows 16

17 PeerStorage Arrays: On Demand Scale when you need, as large as you need it, but remain a single storage pool Scales over: Over 1,000,000 IOPS Over 100 TB storage 17

Mike Reed, Senior IT Director 19

20 What about Enterprise Features? 20

21 Enterprise Features (All Included) Automatic load balancing Point in Time Copies (Snapshots) Remote Replication Volume Cloning Automated Task Scheduler Enterprise Redundancy Complete OS Support Online Service and Upgrades 21

22 SAN Boot with iscsi Easier operations, Faster Restart of Services! Server / or C:\ No local hard drive Disk-less Server Uses iscsi HBA Configure HBA in BIOS to mount boot volumes. iscsi HBA PeerStorage Array Switched Gb Ethernet HBA mounts iscsi volume at boot. Looks like local SCSI disk to OS. Install OS on iscsi volume. OS boots from iscsi volume and mounts it as C:\ drive or / root disk. Data Volume System Disk Data Volume 22

23 Snapshot: Point in Time Copies Improve Backups Instant copy with no performance impact on applications Data Snapshot Snapshots Time Provides instant copies of disks without overhead Allows more frequent backup operations Offers instant restore of disk images Ability to have another server access the snapshot Space efficient Supports 1000s of snapshots 23

24 Quick Recovery with Snapshots Image Restore Example Server iscsi HBA / or C:\ Switched Gb Ethernet Installing Software Patch? Take a snapshot of system disk. Install the software. If there is a problem Shutdown Revert to the snapshot. Reboot PeerStorage Array Instant recovery! Data Volume Data Volume System Disk System Disk 24

25 Using Microsoft VSS for Painless Backups Application Servers Gigabit Ethernet Backup Server App Volume Snapshot Snapshot is copied to tape. 25

26 Multi-Path I/O: High Availability and Performance Application MPIO (Multi-Path Input/Output) Application SCSI MPIO iscsi Gig-E Switches Application Eliminates single points of failure in host connection and network. Aggregates performance over network connections Load balances workload across network switches and NICs/HBAs Easy to setup and configure Works with any combination of NICs and HBAs.
