SMB Overview
 Customer
 Transitioning from internal to external storage
 No dedicated storage administrator
 Cost conscious and value driven
 Require quick and simple implementation
 Solution vs. technology driven
 Challenges
 Growing beyond limitations of internal storage
 Trying to stay within their limited budgets
 Limited IT resources and expertise
 Increasing data protection / recovery at a reasonable cost
 Unaware of functionality that would add value to their business
© 2006 IBM Corporation
Customers Storage Requirements Are Evolving
 Protection – you have more to lose
 Performance – Addressing new application
demands and data loads
 Availability – more people need access
more often
 Scalability – growth without disrupting
operations
 Flexibility – select the options based on your
needs
 Manageability – Manage more data with less
resources

SAS is superior to SCSI
 SCSI is in its 7th generation with the U320 SCSI and has reached its final
iteration
 Serial Attached SCSI (SAS) is the successor to parallel SCSI
 New roadmap and the industry-wide acceptance
 Offers significant performance enhancements
 3-Gbps SAS x4 “wide” ports provide a cumulative bandwidth of up to 12-Gbps for
host connectivity and expansion
 SAS will become the interface of choice for entry-level storage and servers
 SAS and SATA drive compatibility supports tiered storage
What is Tiered Storage?
Tiered Storage is a term used when customers divide their storage according to their data’s
requirements. For example; data that is most commonly used in read environments is stored
on cost-effective SATA disks, while transactional data (databases) is stored on SAS disks that
are suited for random read / write operations.

HPQ MSA1500cs - Pros
 Supports SCSI and/or SATA
 Supports up to 96 SATA drives
 Supports up to 56 SCSI drives
 Somewhat low priced
 $8,995 for 0TB - 1 controller (Ideas International web site 1/2/07)
 $15,400 for 0TB SAN starter kit (Ideas International web site 1/2/07)
 (includes 1 x MSA1500, 1 x controller, 1 x MSA20 SATA drive enclosure,
1 x 4/8 Base SAN Switch, 4 x SFP transceivers & 2 x FCA2214 HBAs &
cables)




Supports Linux, Win & Netware
Viewed as a low-profile 2U solution
Could be used to add SATA to existing HP installations
New MSA1510i provides iSCSI
© 2006 IBM Corporation
HPQ MSA1500cs - Cons
 Uses desktop quality SATA drives
 Extremely low MTBF
 Every drive enclosure is a Single-Point-Of-Failure
 More modules = more SPOF




Based on five-year old MSA1000 controllers
Only two 2Gb/s FC host ports for the entire storage system
Extremely poor performance - single 2Gb data path per controller
HP recommends the same hard drive capacity be installed in an entire disk
enclosure.
 Lacks flexibility & configurability
 Redundant configurations are expensive
 Requires two host bus adapters per server
 Second controller and fibre channel I/O module
 Secure Path software for each server.
