Slide 10: • IT organizations have been battling year-afteryear 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!! copyright I/O Continuity Group, LLC Data Proliferation I’m down and I can’t get up! 10
Slide 11: 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 copyright I/O Continuity Group, LLC 11
Slide 12: 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
Slide 13: 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
Slide 14: 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 Not Consolidated • 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 Consolidated 14
Slide 15: Pre-SAN=Direct-Attached Storage • One-to-one model leads to “server sprawl” when simply more disks may be needed. • Servers are each attached Servers directly to dedicated storage. Not sharing storage • No disk sharing among servers means manual management. Storage Array Storage Array • No dynamic scalability/growth holding disks holding disks • Difficult to know future server capacity needs upfront copyright I/O Continuity Group, LLC 15
Slide 16: • 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. copyright I/O Continuity Group, LLC What is a Storage Area Network?

Slide 17: SAN Reliability Hardware Management • All components are • Dynamic storage means duplicated (two Server HBA’s, anytime a server requires two Switches, two Storage more capacity, the storage Controllers) so if one fails the array can provide it instantly. other part takes over • The server operating system seamlessly. is able to rescan to add the • Vendors receive automatic new disk volume without notification of the failure rebooting. across the internet with rapid • When adding disk capacity an resplacement time. experienced IT technician is • When a new server is added needed. there need for an experienced IT technician. copyright I/O Continuity Group, LLC 17
Slide 18: DAS vs SAN Features DAS • 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) 18 copyright I/O Continuity Group, LLC
Slide 19: • 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 SAN Architecture Servers HBA’s HBA’s Switches copyright I/O Continuity Group, LLC Storage Array holding disks 19
Slide 20: Types of SAN Switches • • • • • • • Fibre 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
Slide 21: SAN vs iSCSI Stacks SAN is fast and robust with minimal network overhead. iSCSI is “bloated” protocol with high network overhead. copyright I/O Continuity Group, LLC 21
Slide 22: Server Host Bus Adapters Fibre Channel HBA’s • • • • • iSCSI Initiators SCSI to Fibre Channel protocol • SCSI to IP packet • Software initiators Hardware initiator – Built-in NICs (teaming) Requires server PCI slot – CPU overhead/latency Speeds: 200/400/800 MB/s • Hardware HBA initiators Bus technology – PCI Express- pt-to-pt – Offloads CPU processing • “Multipathing” load balancing. – MPIO multipathing copyright I/O Continuity Group, LLC 22
Slide 23: 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
Slide 24: 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. copyright I/O Continuity Group, LLC 24
Slide 25: Tiered Storage Strategy Tier 1 High end, Missioncritical Tier 2 High-Mid range Fibre Channel disk Local replication Tier 3 ATA Low-cost Fibre Channel Tier 4 Static, Contentaddressed storage Tier 5 Archives and Tape Availability •Seconds to minutes •Minutes to hours •Hours •Hours •Hours to days Performance •Dynamic workloads •Heavy transaction volume •High performance •Constant workloads •More read access than writes •Moderate performance •More read access than writes •Internet performance •Not applicable Recovery Point •Seconds •Seconds to minutes •Minutes to hours •Up to 24 hours •Up to 72 hours copyright I/O Continuity Group, LLC 25
Slide 26: Questions to Ask • • • • • How much storage do I have now? How quickly is it growing? What are my business objectives? Is my backup window shrinking? How many vendor solutions are going into the mix and can my vendor support them all? • Do all the products work together? • What is the payback period (ROI/TCO) and SLAs? • How much administrative support do I need? copyright I/O Continuity Group, LLC 26
Slide 27: Traditional Direct-attached Hosts LAN Parallel SCSI connection External SCSI Storage Array Each server is separately attached to a dedicated SCSI storage array requiring high storage maintenance with difficult scalability and provisioning. Different vendor platforms cannot share the same external array. copyright I/O Continuity Group, LLC 27
Slide 28: FC SAN- attached Hosts LAN Servers with NICs and FC HBA’s FC Switches 200 to 400 MB/ s Brocade Tape Library FC Storage Array FC SAN’s offer a dedicated block-level infrastructure independent of the LAN. copyright I/O Continuity Group, LLC 28
Slide 29: 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
Slide 30: 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 onthe-fly) – Load balancing workloads – High Availability for no downtime copyright I/O Continuity Group, LLC 30
Slide 31: Physical Servers represent the Before illustration. “Converter” migrates the physical machines over to Virtual Machines running on ESX in the After illustration. copyright I/O Continuity Group, LLC 31
Slide 32: 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
Slide 33: Phases of Virtualization Adoption 1. Separate software from hardware, with ability to have multiple copies of a working software configuration that can be cloned. 1. Separate software from the server, with the ability to run more than one isolated application on a physical server (utilization levels). 2. Ability to run software in virtual machines and dynamically move across physical boundaries. 3. Service broken things without interruption of server & dynamic allocation of apps & new capacity. 4. Manage and automate how application goes copyright I/O Continuity Group, LLC 33
Slide 34: SAN + Virtualized Hosts 2 to 20 VM’s on each server LAN Virtualization server FC Switches 200 to 400 MB/ s Virtualization server Virtualization server Brocade FC Storage Array Tape Library FC SAN’s offer a dedicated block-level infrastructure independent of the LAN. copyright I/O Continuity Group, LLC 34
Slide 35: 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. WAN connection Co-Lo Datacenter copyright I/O Continuity Group, LLC 35
Slide 36: 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? copyright I/O Continuity Group, LLC 36
Slide 37: The Technical Expertise • We are vendor-certified on supported platforms and hardware, including: copyright I/O Continuity Group, LLC 37
Slide 38: 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 copyright I/O Continuity Group, LLC 38
Slide 39: • I/O Continuity Group will help you: – Integrate a “no downtime” solution – Demystify technology and jargon – Blend all technologies into one whole strategy – Save costs on equipment, energy and services – Increase your ROI while reducing your TCO • Once SANs are setup, they run non-disruptively with minimal administration and scale (grow) dynamically. – The question is not IF but WHEN you should adopt or expand a SAN. copyright I/O Continuity Group, LLC 39 Trusted Advisor
