  2. Legacy FC & iSCSI SANs ….not so simple. Cluster Virtualization OS Parallel File System Multi-path IO Software Server Server Server Server Server Server Server Server Server NPIV (Required for Vmotion) HBA Switch (FC) Storage Controller • Difficult to configure • Difficult to Scale • Impossible to manage • Vendor with the best interoperability test matrix wins • (EMC Matrix: 19,000 pages and counting. http://www.emc.com/collateral/elab/emc-support-matrices.pdf)

  3. Legacy Storage Architecture Legacy SAN 1:1 Mainframe to storage Today’s SAN Many:1 Servers to storage Many:1 Virtual to physical servers

  4. Scale-out Ethernet SAN SCSI SCSI iSCSI Fibre Chan • Ethernet SAN • Bare metal performance • No controller bottleneck • Eliminates complex topologies • No more complex multi-pathing • Ethernet simplicity • Lightweight protocol wins! TCP ATA IP AoE Fibre Chan Ethernet Ethernet AoE iSCSI Fibre Channel Storage Protocol Stacks

  5. Coraid Ethernet SAN – Redefining Storage Economics 3 Basic Building Blocks: • Commodity x86 low-cost hardware used to build scale-out, flexible storage servers (“EtherDrive” Arrays): • Non-proprietary, Commodity X86 hardware • Supports SATA, SAS, SSD Drives (can be mixed in a single chassis) • Qty(6) 1Gb, or (4) 10Gb Ethernet Ports --- 230MB - 1800MB/ per sec, per single EtherDrive Array • $500 - $900 per 1 Terabyte • Multiple EtherDrive Models (2u, 3u, and 4u / 8, 16, 24, 36 disk slots) • Redundant Hot-swap power supplies & fans • Ethernet (Layer-2) network is backplane: (No TCP/IP, No iSCSI, No FC) • Provides near Bare-metal performance • Jumbo Frame support (9K) only requirements for Ethernet switches • Market converging to Ethernet, 1Gb, 10Gb, 40Gb, 100Gb • AoE = ATA over Ethernet Storage Protocol: delivers high-performance, low cost alternative to iSCSI & FC SANs • Ethernet SAN driver (AoE) native in all LINUX kernels • Ethernet SAN HBAs (w/ AoE driver) for non-LINUX platforms - Standard Intel dual-ported PCIe, PCI-X cards, (1Gb, 10Gb) • Does not require TCP/IP like iSCSI or proprietary networks like Fibre Channel • AoE is a connection-less protocol that connects servers and storage directly across Layer-2 Ethernet • Does not require user configured multi-path IO (MPIO or NPIV) software • AoE is datagram-based, the bandwidth can scale with additional ports, unlike IP-based solutions • Ethernet SAN packets are automatically sent over every available network path between the server and storage (without MPIO configuration) • iSCSI can be multi-path in the context that each conversation must take place on a single port thus limits max bandwidth of each conversation to the speed of a single port

  6. What is a Coraid Ethernet SAN? Ethernet LAN Non LINUX Server Server Server LINUX Scale-out Ethernet SAN • Performance & Capacity scale linearly with each added Coraid storage array or HBA • Distributed, controller-less, modular architecture scales from a few Terabytes to multi-Petabytes EtherDrive HBAs - Dual-ported Ethernet Cards 1Gb or 10Gb HBA HBA HBA EtherDrive driver - Native in LINUX Kernel Ethernet SAN Capacity Storage LUNs Performance

  7. Simplicity of Coraid Operating System - CorOS • CorOS – Coraid Storage Operating System • Parallel processing scale-out SAN operating system • SAN Fabric + RAID functionality inside a single EtherDrive Server • 3 commands to set up Storage Server – configures in < 1 minute • All LUN’s use static naming conventions (LUN MetaData stored on disks) • MAC address tied to LUN address • Completely eliminates MPIO and Port Binding • Flood entire Network fabric with I/O and Throughput • Supports RAID 0, 1, 5, 6, 10, or JBOD with Global Hot Spares • Continuous RAIDShield – testing fixes bad blocks, reduces drive failure • RAID configuration stored on each disk allows disk portability • Ethernet SAN presents itself as direct-attached disk • Compute side see’s HBA not as NIC but as local SCSI device • SCSI Commands issued from compute side directly to disks via Ethernet SAN • Automatically uses Multiple Paths across all ports to/from storage • Coraid EtherDrive Storage is true scale-out architecture • Controller-less based architecture • Ethernet SAN automatically broadcast all LUN’s to Compute side • Physical connection to SAN Fabric & Jumbo Frame support (9K) only requirements • Transmission Control built in • iSCSI uses Layer-4 TCP for transmission control • FC uses proprietary $$$ hardware

  8. Blistering Performance of Ethernet SAN • Proven performance equal to FC SAN at price points below iSCSI • See ESG Report which compares EMC, NetApp,DAS to Coraid • SR Line: 230MB per sec / per Coraid EtherDrive SR Server • SRX Line: 530MB – 1800MB per sec / per Coraid EtherDrive SRX Server • Customer HPC example: • 100TB Coraid + ZFS = 2Gb per sec, 125K IOPS • Less than $900 per TB • Coraid Microsoft CIFS Driver – 920MB/sec • Using Microsoft 2003 / 2008 • Automatic Multi-Pathing and Link Utilization • Multiple Ethernet Connections to the SAN will automatically be recognized and utilized • Transparent to Host – No configuration required • Host sees 1 LUN regardless of the number of paths utilized • Maximize Throughput • Automatic Failover • If Physical Connection established it will be used • Support LUN Masking, White Lists, VLAN

  13. EtherDrive Host Bus Adapter (HBAs)

  14. Supported HBA’s for EtherDrive

  15. Price-Performance Comparisons

  16. Direct Connection Example • Ethernet Connection • Linux OS can use existing NIC in host • Coraid HBA (Host Bus Adapter) • AoE Drivers on Host • Host Recognizes Available Storage on CORAID Host Ethernet Connection EtherDrive Storage SRxxx SRXxxx

  17. Device Identification • Represented as a Local SCSI Disk • Linux Example • /dev/etherd/e10.10 • e<Shelf#.LUN#> • Persistent Identification • Compare Traditional SAN Protocols • /dev/sdX • X = Arbitrary Letter • No persistent identifier • Requires additional configurations for naming and identification Host Ethernet Connection EtherDrive Storage SRxxx SRXxxx

  18. Multiple Connection Example • SR & SRX – multiple Ethernet interfaces • Supports multiple Ethernet connections • CORAID AOE Driver automatically: • Recognizes multiple paths • Load Balance across all available paths • Increase Throughput • Failover Host Ethernet Connections EtherDrive Storage SRxxx SRXxxx

  19. Multiple Host Access File Server Host A • Multiple “Initiators” (Hosts) may access Coraid storage • LUN – Segmentation of Raw Storage • Each device accesses assigned LUN • LUN Masking • Prevents Host A from even seeing the Server’s LUN Ethernet Switch EtherDrive Storage SRxxx SRXxxx Server LUN Host A LUN

  20. EtherDrive SAN Manager Appliance

  21. Target Solutions Virtualization Cloud Storage EtherDrive’s totally lightweight SAN protocol provides massive I/O for demanding VMware and Xen projects. 10Gb Ethernet SAN performance, petabyte scale-out architecture, JBOD economics.
