Redefining Storage EconomicsCoraid 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

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

HBA HBA EtherDrive driver - Native in LINUX Kernel

Redefining Storage EconomicsSimplicity 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


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

Key Features and Benefits

Ethernet SAN virtualization appliance, provides volume management for EtherDrive SAN storage

Aggregate pools of EtherDrive SR/SRX LUNs together to form small or large virtual LUNs up to 512TB

Each VSX can manage up to 4080 virtual LUNs

VSX can create up to 255 copy-on-write snapshots per virtual LUN

Snapshots can be cloned by VSX and used as read/write copies

VSX can synchronously mirror logical volumes to create a High Availability (HA) storage system with true No Single Point of Failure

For disaster recovery scenarios the VSX supports asynchronous remote replication

Supports 1Gb and 10Gb Ethernet


EtherDrive VSX – True No Single Point of Failure

Synchronous Mirroring:For applications that require high availability, data from one EtherDrive storage appliance can be synchronously mirrored to another to protect against whole array failures. Mirroring creates a simultaneous, exact duplicate version of a physical volume (PV) to a local designated EtherDrive storage LUN target.
