Routing Comparison

Direct DDR2 Registered DIMMs: 1 Channel, 2 Routing Layers with 3rd layer required for power

FB-DIMM: Fewer Layers, Less Routing AreaSource: Intel Enterprise Architecture Group

Serpentine routing is

complicated and uses up

a lot of board area

FB-DIMMs:2 Channels, 2 Routing Layers (includes power delivery)

Fewer signals and

no trace length

matching minimizes board area

DDR2 vs. FBD Config Comparison

Slightly larger delay for the additional buffer

FB-DIMM provides very high sustained throughput due to simultaneous reads/writes

What to expect in the SCSI to SAS transition

®


16


The ProblemParallel architecture can no longer reliably keep up with data rate increases.Cost of deploying multiple HBAs to support SCSI 16 device limitRising need for flexible solution to support either Online or Nearline storage

Current Parallel SCSI architecture has hit a ceilingCurrent Parallel SCSI architecture has hit a ceiling

®


17


The Solution: Serial Attached SCSI

SAS is the next generation of SCSISame SCSI protocol for data transferSerial instead of Parallel interconnect• Same cabling/connectors/physical interface as SATA

Point to point architecture• Unlike shared bus of SCSI (15 drives maximum per channel)• Ports can be linked together – ‘Wide’ ports for larger throughput to Expanders• 300MB/s per port initially, moving to 600MB/s and more in future

SATA Tunneling Protocol provides compatibility with SATA devices• Allows lower cost drives/devices to be used in the SAS environment

Expanders provide greater performance and flexibility

®


18


SAS vs. SCSI

Benefits of SASTransparent application migration from SCSI->SASReliability is equivalent using SAS or SCSI drivesSATA drives can be used in SAS environmentSAS drives are dual ported, providing full redundancy to drives, if desired

Transition to SAS from SCSISAS industry launching Q1’05, and will be widely available by ’06EPSD is a technology leader, and SAS is the next technologySCSI will continue to exist as commodity for several years - ~2010

®


19


SAS vs. SATA

Benefits of SASSAS architecture supports enterprise environments by design

• Protocol supports larger drive configurations• SAS drives are designed for higher performance and reliability (MTBF)• SAS drives are dual ported, providing full redundancy to drives

Benefits of SATASATA integrated into current and future generation chipsetsSATA technology has 1.5year head start on SAS

• SATA is now stable, and infrastructure is established• Low risk of unexpected technology or interoperability issues

SW and HW RAID greatly reduces reliability gap

Expander Overview

Expanders allow access to multiple targetsNon-blocking switch architecture – basically a simple FC switchAllows any number of incoming SAS controller ports to connect to a large number of SAS or SATA targetsAggregate throughput from multiple targets

• Provides the functionality to fully utilize the available bandwidth/IOPS of the connection

Two types of Expanders: Edge and Fan-OutEdge: Direct and Subtractive Routing only

• Supports direct devices and ONE other Expander connected (subtractive)• Primary inside the box need

Fan-Out: Direct, Subtractive, and Table Routing• Supports direct devices and up to 128 other Expanders (routing to the necessary

connected Expander via the internal routing table)• Tables can be smaller than max of 128 – this is the common implementation today• Primarily large port count/external box usage
