VMware Infrastructure 3
Key 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

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

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

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

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

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 redirected 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.

SAN Boot
Easier operations, Faster Restart of Services!
 No local hard drive
– Disk-less Server
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.
