Data Proliferation• IT organizations have been battling year-after-
year information growth rates of 50 to 100 percent.
• This trend will continue into the next decade.• Just storing more data is no longer an option. • Consolidating multiple application tiers into a
single common infrastructure will lower costs and improve service levels.

Data Explosion!!
I’m down and I can’t get up!
IT Challenge• Every new IT trend involves a:
• New vendor solution to integrate with current systems• New hardware requirements and software licensing• Need for special talent and integration strategies• More energy costs, more datacenter space, extra
cooling• Need to protect data without a lot of difficulty
• Data capacity doubles every 12-18 months (based on average business growth)
• Managing data becomes difficult and expensive• Backing up data takes longer as more data
accumulates
11copyright I/O Continuity Group, LLC
Phases of Consolidation
• Reduce the need for valuable resources:
• Phase 1: All servers share the storage array(s) on a Storage Area Network
• Phase 2: Many applications running as “Virtual Machines” on fewer servers
copyright I/O Continuity Group, LLC 12
Top Three Questions• Why is storage important?
– 80% of most company’s capitalization– If you lose your data, corporate stability is lost– Revenues suffer when systems are down
• How can consolidation save $$$ ?– Less Hardware– Fewer IT staff– Reduced Energy Consumption
• How do you choose?– Storage Area Networks (Fibre Channel or iSCSI)– Virtualization (VMware, Virtual Iron, Hyper-V)
copyright I/O Continuity Group, LLC 13
Storage Basics• Every operating system and application
NEEDS a DISK to hold data:• Web sites, e-mail servers, databases,
video recordings, etc
• What happens when data grows quickly or disks get full?
• Data keeps growing
• Adding more disks can lead to interruptions and downtime.
• Server becomes unmanageable when it is difficult to predict storage needs.
copyright I/O Continuity Group, LLC 14Consolidated
Not Consolidated
Pre-SAN=Direct-Attached Storage • One-to-one model leads to
“server sprawl” when simply more disks may be needed.
• Servers are each attached directly to dedicated storage.
• No disk sharing among servers means manual management.
• No dynamic scalability/growth• Difficult to know future server
capacity needs upfrontcopyright I/O Continuity Group, LLC 15

What is a Storage Area Network?• Storage Area Networks (SANs)
consolidate disks on their own high-speed dedicated network.
• Storage array allows addition of more disks on-the-fly.
• Servers can connect to more disk space without rebooting.
• Move more data faster and more efficiently.
• The “de facto” storage solution.

SAN ReliabilityHardware
• All components are duplicated (two Server HBA’s, two Switches, two Storage Controllers) so if one fails the other part takes over seamlessly.
• Vendors receive automatic notification of the failure across the internet with rapid resplacement time.
• When a new server is added there need for an experienced IT technician.
Management
• Dynamic storage means anytime a server requires more capacity, the storage array can provide it instantly.
• The server operating system is able to rescan to add the new disk volume without rebooting.
• When adding disk capacity an experienced IT technician is needed.

DAS vs SAN FeaturesDAS
• Standalone disk enclosures• One-to-one model – no
switched network• Hardware intensive• Management intensive• No redundancy (expect
downtime)• Capacity , management and
disk allocation is not seamless• Average speed/bandwidth 200
MB/s (with overhead)
SAN• Consolidated disk enclosures• One-to-many model with
switched network• Hardware shared• Seamless management• No single point of failure (no
downtime) “Runs by itself”• SAN foundation is required for
virtualization• Average speed/bandwidth up to
800 MB/s (less overhead)
copyright I/O Continuity Group, LLC 18
SAN Architecture• Current “de facto” storage design• Price has come down approx 80%
in 8 yrs• All devices must be compatible• Two connections to end devices–
no single point of failure• Dynamic scalability/growth
through plug-n-play disk shelves• Servers simply rescan for more disk
space

Types of SAN SwitchesFibre Channel SAN
• Fast Optical switches • Bandwidth 200- 800 MB/s• Low latency (quick
response)• More expensive• Supports demanding
workloads• Mission-critical server
applications• Limited distances 500 km
IP SAN (iSCSI)• LAN/WAN Switches (GigE)• Bandwidth avg 100 MB/s• High latency (more processing
overhead in software)• Less expensive• Supports less complex
workloads• Second-tier server applications
( ¼ performance for ¼ price)• Max distance unlimited
copyright I/O Continuity Group, LLC 20
SAN vs iSCSI Stacks
copyright I/O Continuity Group, LLC 21
SAN is fast and robust with minimal network overhead.
iSCSI is “bloated” protocol with high network overhead.
• SCSI to IP packet• Software initiators
– Built-in NICs (teaming)– CPU overhead/latency
• Hardware HBA initiators– Offloads CPU processing– MPIO multipathing
Server Host Bus AdaptersFibre Channel HBA’s
• SCSI to Fibre Channel protocol• Hardware initiator• Requires server PCI slot• Speeds: 200/400/800 MB/s• Bus technology
– PCI Express- pt-to-pt• “Multipathing” load balancing.
iSCSI Initiators
copyright I/O Continuity Group, LLC 22
Types of Disks and Arrays
• ATA/IDE – mostly desktops• Parallel SCSI – slower data transfer (200 MB/s)• SATA (Serial ATA) – low-cost FC drives• SAS (Serial attached SCSI) – point-to-point
• FC (fibre channel) – faster 400 MB/s– RPM speeds 10,000-15,000 – If a disk or hardware part fails, the vendor
automatically sends a replacement
copyright I/O Continuity Group, LLC 23
Top-to-bottom approach• Evaluate your current server/storage
arrangement and data growth• Prioritize application importance• Measure server workloads and current
performance • Tailored storage design: assign each server to
the proper storage “tier” (see next slide)• Match current and future capacity needs to
vendor storage array options.

Why Virtualization?• Next level of consolidation running on top of
SAN for best performance and automation.• Consolidate multiple physical machines into
“Virtual Machines” on fewer physical servers.• Allows rapid deployment of new applications by
simple right click operation.• Less hardware means:
– Less energy consumption, heat-generated to be cooled, datacenter space occupied and IT staff.
– ROI and TCO are maximized copyright I/O Continuity Group, LLC 29
Server Consolidation• New virtualization solutions gaining popularity
– VMware – Fortune 100 market niche– Virtual Iron – SMB market niche– Windows Server 2008 Hyper-V – July RTM
• Must have “shared storage” SAN in place to optimize key virtualization features:– Live Server migration (move virtual machines on-
the-fly)– Load balancing workloads– High Availability for no downtime
copyright I/O Continuity Group, LLC 30
Physical Servers represent the Before illustration.
“Converter” migrates the physical machines over to Virtual Machines running on ESX in the After illustration.
31copyright I/O Continuity Group, LLC
Virtualization-Value Proposition• Automation and management• Obtain much higher utilization out of your hardware
assets while building a more robust infrastructure at the same time– If a physical server fails, a “Virtual Machine” moves itself– Once installed, solution runs by itself*– Infrastructure become management-free
• **Requires a properly designed SAN foundation• Initial complexity can be simplified
– One-time migration of physical servers to virtual servers– One vendor organizing all the details.
copyright I/O Continuity Group, LLC 32
Phases of Virtualization Adoption1. Separate software from hardware, with ability to have
multiple copies of a working software configuration that can be cloned.
2. Separate software from the server, with the ability to run more than one isolated application on a physical server (utilization levels).
3. Ability to run software in virtual machines and dynamically move across physical boundaries.
4. Service broken things without interruption of server & dynamic allocation of apps & new capacity.
5. Manage and automate how application goes through disaster recovery.

SAN Extensions• FC SANs are limited in their connection
distance to around 500 km.• Disaster recovery sites may exceed FC
distance from your datacenter.• Data replication solutions can bridge the gap
moving data from the storage stack to the standard networking stack.

Questions to ask
• How many servers do I currently have and how many do I add every year? (aka server sprawl)
• How much time do IT staff spend setting up new servers with operating system and applications?
• How often do my servers go down?• Is our IT budget shrinking?• How difficult is it to convert a physical machine
to a virtual machine with each option?• What hardware and guest OS’s are supported?

Vendor Neutral• There are four main benefits to designing SAN’s
independent of any single equipment vendor. • The relative importance of these benefits will change
depending on your priorities and which vendors you choose. The benefits in some cases* are:– Lower costs – Getting the best possible technology – Greater flexibility for future technology
improvements – Non-proprietary and non-exclusivity models– * DOES NOT APPLY TO ALL VENDORS
