Forrester Recommends IP StorageForrester 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”

iSCSI – What is it?iSCSI – What is it?

iSCSI (Internet Small Computer System Interface) specifies a way to “encapsulate” SCSI commands in a TCP/IP network connection:

Explains how to extractSCSI commands and data

Provides information necessary toguarantee delivery

Contains “routing” informationso the message can find itsway through the network

iSCSI in OperationiSCSI 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

Accessing a Volume Using iSCSIAccessing 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.

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.
