  1. The Marriage of Virtual Systems with Virtual Storage

  2. VMware Infrastructure 3Key Features Enabled by Networked “SAN” Storage VMware Infrastructure 3 • VMotion • Online migration of running virtual machines without interruption • DRS - Distributed Resource Scheduling • Global scheduler optimizes resource usage based on current workloads • VMware HA • Automated rehosting and restart of virtual machine in case of server failure • Consolidated Backup • Centralized file level backup with no host agents

  3. VMware Infrastructure 3 iSCSI SAN Integration Host OS Virtualization Layer Guest OS iSCSI SAN • Native initiators • Software initiator • NIC teaming • Max of 16 GbE ports • Divided up across client access, storage access, and Vmotion • QLogic QLA4010 • Active/passive multipathing • SAN Boot • 2x QLA4010 • Target discovery • CHAP Authentication

  4. Forrester Recommends IP Storage Forrester Recommendations: • “Choose IP-based storage over fibre channel when possible” • “Firms should evaluate IP-based storage first when deploying new or upgrading existing networked storage” • “Choose IP-based storage to reduce cost and complexity” iSCSI is the only storage protocol recommended by Forrester for all Enterprises Forrester Claims: • “EqualLogic holds its own as an iSCSI storage systems vendor” • “Ethernet and TCP/IP networking technologies are ubiquitous in firms today”

  5. iSCSI Connections Will Exceed FC in 2008 iSCSI and FC Host Connections Units 1,800,000 1,600,000 1,400,000 1,200,000 1,000,000 FC Server Attachments iSCSI Server Attachments 800,000 600,000 400,000 200,000 Source: Gartner Presentation, “The Future of iSCSI SANs” by Robert Passmore.

  7. iSCSI SANs • Utilizes iSCSI (standards-based IP technology) • Provides block level storage • Leverages the large installed base of Ethernet and IP networks • Enables storage to be accessed over LAN, MAN, or WAN environments • Provides an affordable infrastructure with connectivity up to 10 times less expensive than FC SANs • Utilizes existing IP knowledge base Server GbE Switch Disk Array Tape Library

  8. iSCSI Standard Brings Interoperability to SANs • Familiar technologies – now used together • Same SCSI commands – Over 20 years of SCSI • Same network transport – Over 30 years of IP networking • IETF RFCs: 3720, 3721, 3722, 3723 iSCSI Storage (Targets) Servers (Initiators) Ethernet Frame TCP/IP SCSI Packet • Complete OS support • Boot from SAN • Enterprise SAN backup • Tape and disk vendors • Multipath I/O • Clusters • Storage over distance • HBAs

  9. iSCSI – What is it? • iSCSI (Internet Small Computer System Interface) specifies a way to “encapsulate” SCSI commands in a TCP/IP network connection: IP Header TCP Header Gigabit Ethernet iSCSI Header SCSI commands and data Explains how to extract SCSI commands and data Provides information necessary to guarantee delivery Provides Link Addressing, large frame sizes, and flow control Contains “routing” information so the message can find its way through the network

  10. iSCSI in Operation • iSCSI initiators issue SCSI “commands” to request services • iSCSI target services requests “Data” to requesting initiator • iSCSI transmits and receives block storage applications over TCP/IP networks by encapsulating SCSI commands into TCP and transporting them over the network via IP Local Disk (C:) Data Volume (F:) Data Volume (G:) iSCSI Target iSCSI Storage HBA or NIC Server Local Disk (C:) Data Volume (F:) Data Volume (G:) iSCSI Initiator

  11. Accessing a Volume Using iSCSI • To access a volume, a host needs only an industry-standard iSCSI initiator. Each major operating system supports an iSCSI initiator. • Host system access to a volume is through the group IP address and the iSCSI target for the volume. • After the initial iSCSI connection and authentication, the host is re-directed to a network connection that is optimal for performance (for example, a network interface on the member that contains the requested data). • Once connected, a volume appears as a SCSI disk that can be formatted with the operating system’s normal utilities.

End-to-End Hardware Reliability Hotswap Drive Carriers Dual Controllers Dual Power Supplies Dual Fans • Fully Redundant & Hot Swappable (5-9’s Availability) • Controllers • Disk drives • Fans & power supplies • High-end Components • Three 1Gb network interfaces • SATA II drives • 2 GB battery-backed mirrored memory • Enclosure Monitoring System • Temperature • Component status • Disk drive health

Server and Storage Virtualization SolutionsSelf-Managing Storage Enhances Virtual Infrastructure SwitchedGb Ethernet • Customer Objectives: • Reduced server and storage capital expense • Resource maximization across servers and storage for maximum performance • Flexible movement of servers, storage and applications across hardware platforms • Key applications: • Server consolidation • Business continuance • Hosted desktops • Development and test • Why EqualLogic: • Scale infrastructure without downtime • Simplify management of virtualized infrastructure • Rapidly provision and deploy virtual servers • Protect and recover data quickly • Replicate servers and data stores for easy disaster recovery PS Series Array

  18. SAN BootEasier operations, Faster Restart of Services! SwitchedGb Ethernet • No local hard drive • Disk-less Server • Use iSCSI HBA or PXE • Configure BIOS to mount “boot” volumes. • 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. • Improved Data Protection • Fast Recovery • Better DR operations Server / or C:\ iSCSI HBAor BIOS Boot PS Series Array Data Volume SystemDisk Data Volume
