Redefining Storage Economics Scale-out Ethernet SAN • Performance & Capacity scale linearly with each added Coraid storage array or HBA Ethernet LAN Non LINUX LINUX Server Server HBA EtherDrive driver - Native in LINUX Kernel Server HBA HBA EtherDrive HBAs - Dual-ported Ethernet Cards 1Gb or 10Gb Ethernet • Distributed, controller-less, modular architecture scales from a few Terabytes to multiPetabytes SAN Capacity Storage LUNs Performance Simplicity of Coraid Operating System - CorOS Redefining Storage Economics CorOS – Coraid Storage Operating System 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 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 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 Blistering Performance of Ethernet SAN Redefining Storage Economics 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: Coraid Microsoft CIFS Driver – 920MB/sec Using Microsoft 2003 / 2008 Automatic Multi-Pathing and Link Utilization 100TB Coraid + ZFS = 2Gb per sec, 125K IOPS Less than $900 per TB 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 Cost-Effective Scale-out Storage: EtherDrive SR Series Redefining Storage Economics High-Performance Scale-out Storage -
