SAS Basics and Benefits
SAS – Serial Attached SCSI
– A serial communication protocol designed for transfer of SCSI
commands and data to and from devices over point-to-point
interconnections
Key Benefits
– New roadmap with industry-wide acceptance
– Significant performance enhancements
• 3-Gbps SAS x4 “wide” ports
– Cost equivalent to parallel SCSI
– Freedom from 15 drive maximum per SCSI channel

SAS Special Considerations
Distance limitations – 8 meters per discreet connection
Perceived complexity based on the newness of the technology
SAS expanders, which will support SAN-like capabilities for SAS,
are still in development
Limited to the number of servers that can be attached – based on
the number of SAS host ports on the storage system

iSCSI Basics and Benefits
iSCSI - internet Small Computer System Interface
– A network protocol that enables transmission of SCSI commands
and data over an IP-based network usually via an Ethernet interface
Key Benefits:
– Low cost
– Less complexity
• Extensive knowledge base – expertise in every IT organization
– Flexible configuration topologies
– Extensive reach with no distance limitations
– Future performance
• 1Gb/s today with roadmap for 10Gb/s and beyond

iSCSI Special Considerations
Network congestion risks the dropping of frames – important
to evaluate configuration to foresee any bottlenecks
Achievable performance is misunderstood
– Hardware and connection parameters can be leveraged to achieve
desired performance
Security at risk when sharing IP storage networks with the
existing network
– Separate storage traffic from normal LAN traffic
Disparate expertise and confusion over storage and networking
IT roles

FC Basics and Benefits
FC – Fibre Channel
– A serial networking interface that supports the transmission of upper
level protocols – including SCSI command sets and data – over fiber
optic or copper cables
Key Benefits
– Scalable – supports up to 16 million addresses.
– Distance – 10,000 meters maximum cabling length
– High bandwidth – low latency and high IOPs
– Investment protection – auto-negotiating link speeds allowing for
seamless integration into an existing 1Gb/s or 2 Gb/s environment
– Congestion free with credit-based flow control delivering data as fast
as the destination buffer is able to receive it.

FC Special Considerations
Steep learning curve for administrators unfamiliar with deployment
and management
Expensive and complex
– Costly FC SAN equipment and maintenance
– Training personnel internally or hiring a service company is a
significant addition to TCO
Low-cost servers will typically not be included as the investment
to attach it can outweigh the cost of the server itself – does not
always make financial sense to deploy
