VMware Storage Stack

The Storage Stack in VI3 ESX 1 VM1 VM2 VM3 VM4 VM5 ESX 2 Selectively presents logical containers to VMs VD1 VD2 VSCSI Disklib ESX Storage VMFS Stack LVM VD3 VD4 VD5 VSCSI Disklib ESX Storage VMFS Stack LVM Provides services such as snapshots Provisions logical containers Aggregates physical volumes SAN switch LUN 1 LUN 2 LUN 3 Clustered host-based VM and file system Analogous to how VI3 virtualizes servers Looks like a SAN to VMs A network of LUNs Presented to a network of VMs

Big Focus on I/O Performance One ESX 3.5 box drives: 3 FC Arrays 500 spindles 77 TB of disk space Enough I/O horsepower for: 200,000 Exchange Mailboxes 150 medium databases

ESX Storage Connectivity Choices Shared Storage (Clustered) Local Storage (Stand Alone) VMFS (Formatted) NAS/NFS (File Based) VMFS (on iscsi) VMFS (on FC SAN) RDMs (On FC SAN or iscsi) iscsi HBA SW initiator Physical Mode Pass-Thru Virtual Mode Persistent Undoable

VMware and the Storage Ecosystem

VMware Goals: Partner Enablement Maintain vendor neutrality In conjunction with partners, drive innovation to deliver superior customer experience Create opportunities for partners Accelerate time to market for storage I/O certification Extend and leverage value of partners existing products Build new offerings

Storage I/O and VMware Certification

Storage I/O Certification CVA 1.0 released in Oct 07 CVA 1.0.1 (Dec 07) and 1.1 (Feb 08) VMTN forums Communications (70+) Change in MSCS policy Direct connect FC VMware Accredited Testing Labs Cognizant AppLabs

vhct Program Storage Partner Ecosystem is growing Select Partner Program ~35 (20+ are Storage partners) Select Partner Program Program guide Email support system Monthly newsletter (started in April) VMware Certified Logo Future Enhancements ESX debugging and troubleshooting guides

VI4 and vhct VMware will require a re-certification for all Server and Storage devices A new version of CVA will be available (2.0) Updated to VI4 feature set CVA 1.1.1 will not be compatible with VI4 Partner Beta planned Partner training planned Partner communications will announce availability to Global/Premier Partners and Testing Labs

VI3 Customer Storage Trends

Shared Storage Dominates Current (as of 10/07) Future (end of 08) Q: What proportions of your current VMs running on ESX Server are on the following types of storage? (N=7320) Trend is to move from DAS (or internal disk) to shared storage within the year.

Software iscsi Preferred In-guest vs. Hypervisor level If at hypervisor level, then s/w or h/w? Q: For the majority of your current and planned VMs stored on iscsi arrays, where is the iscsi initiator placed? (N=7320)

Storage Presentation: VMFS Where do customers store their VM s?...on raw devices (RDMs, iscsi in-guest) 11%...in a filesystem (VMFS, NFS) Are customers 100% filesystem, 100% raw device, or some mix? Mix of both Only use filesystem 89% Only use raw device 5% 29% 66%

VMware Storage Functionality: Directions and Partner Opportunities

Key VI Initiatives VDI Improve desktop security and manageability Business Continuity Reduce cost & complexity of backup, D.R. Branch office & SMB Deliver availability at lower cost & complexity Server Consolidation & Containment Power, cooling, space, server sprawl

Managed Desktops Virtual Desktop Infrastructure (VDI) Full desktops run in the data center Connect to desktop from anywhere Centralized management More efficient resource usage Higher availability Online and offline mode VMware Infrastructure 3 Centralized Virtual Desktops VMware Virtual Desktop Manager Thick or Thin Clients

VDI The VDI market VDI s special storage needs Opportunities for partners

VDI Market Opportunity Server revenue opportunity ($B) Revenue ($B) $1.2 $1.0 $0.8 $0.6 $0.4 $0.2 Source: IDC March 2007 Today: 500M total business PCs IDC projects 5% go VDI by 2011. That s 250PB of new storage opportunity $1.1B $0.0 2006 2007 2008 2009 2010 2011

VDI Challenges Challenges VDI Impact PC Management is time consuming & inefficient Desktop Operating Costs are High Low End User Service Level Agreement (SLA) levels Security and Compliance Risks Streamlined & simplified desktop management Reduced Desktop maintenance & support costs Improved End User SLAs & Desktop Business Continuity Improved Security and Compliance

VDI The VDI market VDI s special storage needs Opportunities for partners

Storage and VDI Reduce the required storage while maximizing performance Enable the provisioning of large numbers of virtual machines in real time Enable laptops to run disconnected, and resync upon reconnecting

Scalable Virtual Images Separate the user data from the OS & app image Then, leverage lightweight clones to handle the OS & app disk. Dramatically reduce the amount of storage consumed 25 MB Clone 25 MB Clone 25 MB Clone 10 GB OS Ratio % Savings 1:50 85%+ 1:100 90%+ 1:100 0 95%+

VDI The VDI market VDI s special storage needs Opportunities for partners

VDI: Partner Opportunities De-dupe Integrate array-based lightweight clones (aka writeable snapshots) with VMware s linked clones / SVI approach Speed the creation of light-weight clones Explicitly keep base disks in cache to speed access Replication to laptops and resyncing

Business Continuity/DR Customer behaviors What VMware is doing Opportunities for partners

Customers: Virtualization==BC/DR More than half of customers deploy virtualization for business continuity and disaster recovery purposes N=2265, Winter 2006 VMware customer survey

Customer DR Example Primary Datacenter Recovery Site Virtual Infrastructure Replication Virtual Infrastructure 30 miles FC SAN RPO of 15 minutes and RTO of 24 hours Reduced TCO by 50% Saw ROI of 600% in four months FC SAN

Storage for VI Business Continuity Backup and replication Offload it, make it fast On a per-vm basis Capable of non-disruptive audit Resilience for all sorts of failures Handle: site, campus bldg, single array, etc. While keeping that failover hardware usefully used

Partner Opportunities: BC/DR Backup and replication Offload it, make it fast On a per-vm basis Capable of non-disruptive audit Write replication adapters for Site Recovery manager Directional: enable VCB to leverage array-based snapshots Directional: storage services on a per-vm basis Resilience for all sorts of failures Handle: site, campus bldg, single array, etc. While keeping that failover HW usefully used Implement array-based mirroring with both arrays allowing writes (i.e. fully activeactive). for both LAN/MAN and WAN.

SMB Challenges + Investments VMware SMB Market Survey, June, 2007 n = 501 Q. The following is a list of potential problems that your company could have with its computing environment. Please rate how serious of a problem each one is for your company. (On a 1-8 scale, 8=extremely serious problem). Q. Please indicate the relative amount of investment your company is likely to put into addressing these issues in the next 12 months. (On a 1-8 scale, 8=very high investment in addressing this). Top spending areas are DR, backup, security and availability
