technology marches forward, todays data center
managers have more choices for connecting servers
to storage in the enterprise. Fibre Channel is
clearly the leading technology for this, however
iSCSI has become an excepted alternative. The
question becomes Is it right for your
enterprise?

What is iSCSI?
8
What is iSCSI?

• iSCSI is Internet SCSI
• Block level SCSI protocol I/O over Ethernet
• Conceived by IBM and Cisco in 1999
• Beat out competing proposals for same
  functionality
• Several years to achieve standards definition
• February 2003
• What are the promises of iSCSI?
• Reduced complexity
• Inexpensive
• Lower support costs
• Abundant trained personnel
• IP Infrastructure leverage

Delivery of block storage data (initiator,

Explains how to extract SCSI commands and data
(iqn, ISID, send targets, etc)
Guarantees delivery and transport of the
packet (TCP Windows, port numbers, ACKs,
ordering, etc)
Provides routing capability so that the packet
can efficiently find its way through the network
(IPv4, ARP, IP Frag, etc)
Provides physical network capability (CAT5, MAC,
FDX, etc)
11
Is iSCSI a SAN?

• Anatomy of an iSCSI SAN
• Ethernet Switches - Without modification,
  installed Ethernet switches move iSCSI data
  between servers with iSCSI HBAs and storage.
• Storage Routers - By converting Fibre Channel to
  iSCSI, storage routers bridge Fibre Channel
  servers and storage to Ethernet networks.
• iSCSI Host Bus Adapters (HBAs) - PCI adapters
  provide servers with a connection to iSCSI
  storage directly or via an Ethernet network.
• iSCSI Storage - Disk and tape subsystems include
  embedded iSCSI interfaces to a host or network.

12
TOE vs. NIC The types of iSCSI adapters
13
All adapters are not created equal..

• There are several types of ways to implement an
  iSCSI SAN solution.
• Host Bus adapter Choices
• NIC- Network interface card and iSCSI software
  drivers
• Partial offload TOE ( TCP Off Load Engine) HBAs
• Full offload TOE HBAs
• TOE iSCSI offload
• TOE iSCSI digest offload

14
iSCSI Performance can differ

• TCP/IP Processing is CPU Resource Intensive
• 1Hz CPU per 1bps
• 1GHz CPU for a 1Gb link/ Card
• TCP Offload Engine (TOE)
• Hardware Acceleration of TCP/IP

iSCSI HBA key Features and Benefits
Before purchasing an iSCSI HBA, make sure your
selection includes the best benefits and
features
19
Would I ever use a NIC over an Offload HBA?

• Performance is not an Issue
• Cost is an Issue, dont want to pay more for the
  card then the Server.
• Simple connectivity to your Storage or Tape
  Backup.
• No PCI expansion

20
Cost Effectiveness of iSCSI
21
The iSCSI Value Proposition

• Exploits IT staff knowledge of TCP/IP
• Trained staff, IP is the predominant networking
  technology
• Lower total cost of ownership
• Reduced overall system cost
• Existing infrastructure
• Distributed Storage
• IP everywhere
• Network Convergence
• Use the same network for SAN and LAN

22
The reality - Price vs. Performance

• One of the most attractive aspects of iSCSI is
  its proposed low cost deployment. It really
  comes down to Price vs. Performance.

23
Where and When to deploy iSCSI
24
Is iSCSI right for you?

• Determine your needs
• Key areas to deploy iSCSI in the Enterprise
• Remote Data access
• Low level server needs
• Remote DR
• Boot over iSCSI

25
Attaching servers for Remote Boot

• Diskless Servers
• Reduced Hardware Operating Costs
• Increased Reliability and Availability
• Configuration Flexibility
• Improved Security
• Simplified Management

Low Cost Servers

FC Storage (boot)
26
Remote Boot via iSCSI

• iSCSI HBA Required
• Uses Familiar OS Storage Interface
• Full iSCSI Offload plus TOE
• Appears to BIOS as a HDD
• Standard BIOS
• Easy to Administer and Maintain
• True remote block storage
• DAS Equivalent Performance

iSCSI / FC Comparison
31
iSCSI Performance vs. FC

• Block Data movement is the key here
• FC today has capabilities of up to 4Gb/sec or
  400MB/sec or 800 full duplex
• iSCSI runs at 1Gb/sec or 100MB/sec today
• With 10Gb not far off
• Fiber Channel is still the leader for fast and
  sustaining movement of large blocks of data
• iSCSI is geared more toward lower priority and
  long distance data moves

32
Network Infrastructure Differences

• What do you need?
• Fibre Channel
• Fibre Optic network cabling
• FC HBAs
• FC Switches
• SFP media
• iSCSI
• Existing Ethernet cabling infrastructure
• Routers, Switches, Hubs
• NIC or TOE HBAs
• Ethernet or Optical media
• However best performance requires a separate
  Ethernet network dedicated for iSCSI. Higher
  performance TOE HBAs also increase performance.

Extending the SAN for Cost Effective Connectivity
and Disaster Recovery
LIVE Webcast June 14th, 2006
Todays data center managers are constantly
dealing with managing growth, and at the same
time new technology advancements. Last quarter
we talked about introducing iSCSI into the data
center and the benefit that introducing iSCSI can
have. How do we now connect low cost iSCSI
servers into datacenter fibre channel storage?
Data center designers also need to ensure
uptime and a seamless migration and failover from
one data center to another in the case of a
disaster. How can this be accomplished at a
reasonable cost without the traditional
complexity that comes with long distance
SANs? This web cast has been designed to answer
these questions and offer you some new ideas on
data center connectivity.
