1 Virtualized Storage for VMware Virtual Infrastructure. Presented by: John Martin Consulting Systems Engineer, Net

2 What If You Could... Backup and restore your VMs instantaneously Easily protect all your virtualised data with DR Save 50% on your storage, power, cooling, and space Reduce virtual server and virtual desktop data, enabling 50% space savings, or more Automate your most labour-intensive data management tasks Clone and provision storage as quickly as your VMs Do all of this with one architecture in any environment 2008 Net.

3 Agenda Virtualisation Increases Storage Demands What can be achieved How to Increase Operational Efficiency & Reduce Costs Data Availability, Backup & DR Challenges and Solutions 2008 Net. All rights reserved. 4

4 Virtualisation Increases Storage Demands Number of applications per server Number of physical servers Number of apps down on storage failure Data lost on dual-disk failure Backup data volume Meeting backup window Disaster recovery Provisioning 1 Before Virtualising Servers x 1x Feasible Costly/complex Slow/complex After Virtualising Servers x 10x Maybe not More complex Storage servers 2008 Net.

5 What can be achieved BT is one of the world's leading providers of communications solutions and services operating in 170 countries. Increased efficiency: 1356 physical servers to 102 Power savings of ~1MW Space savings of 293 racks Over 4000 ports saved Increased capabilities: Activation times down to minutes Backup went from 96 hours to 31 minutes Enabled capacity on demand business model 2008 Net.

8 Server Virtualisation Not Aligned To Storage Server Virtualisation Traditional Storage Computing Power Storage Capacity System Memory Efficient resource sharing Creates a liquid environment Available IOPs (work I can do) No resource sharing, bad trade-offs Pockets of orphaned I/O and space Traditional storage does not provide the flexibility available with server virtualisation 2008 Net.

9 Storage Virtualisation Makes a Difference Server Virtualisation Net Storage Virtualisation Computing Power Storage Capacity System Memory Efficient resource sharing CPU and memory are pooled Available IOPs (work I can do) Efficient resource sharing No trade-offs Capacity and IOPs are pooled Net provides to storage what VMware provides for servers 2008 Net.

11 Thin Provisioning: What is it? Monitoring and reacting to capacity growth is critical. Thin Virtual Disks Thin Provisioned Datastores Used Capacity Provisioned Capacity Physical Capacity! Physical Capacity 2008 Net. All rights reserved.

12 Thin Provisioning Sample Deployment for VMware VMFS Datastore VMs and virtual disks. Virtual Machines perceive full-sized virtual disks. Optionally, virtual disks themselves are thin provisioned. VMFS Datastore 500 G 600 G 500 G ESX creates full-sized VMFS datastore Thin Provisioned LUNs Thin Provisioned FlexVols aggregate Make sure you can grow your underlying aggregate to support the space you ve provisioned! 2008 Net.

13 Fast and Efficient Copies: Cloning for Identical Servers Before Virtualisation After Virtualisation Many servers Many copies of data Many virtual servers Many virtual copies of data Enabling Net technology: FlexClone 2008 Net. All rights reserved. 14

14 Accelerating Virtual Infrastructure Deployment: The Process with Traditional Tools Production VM VMware Clones The traditional challenge with creating many Virtual Machines VMware clones are based on templates Dev 1 Dev 2 Dev N Deployment consumes time = size of template Are managed serially one at a time Test 1 Test 2 Test N Consume storage 100% redundant 100% additional storage for each VMware clone 2008 Net.

17 Traditional Storage Utilisation Desktop MgtResource Mgt VMware template clones Clones are 100% identical Including OS and applications Clones consume storage equal to size of template By design VMware environments are very redundant 2008 Net. All rights reserved.

18 Production Data Deduplication Dedupe removes redundant data Supports FCP, iscsi, & NFS 50% 70% storage reduction >90% with VDI Net deduplication provides the same benefits as the VMware shared cached memory functionality 2008 Net. All rights reserved.

19 Reducing storage costs with Net virtualised storage technologies Deduplication 50% Saves up to 95% for full backups; 25% to 55% for most data sets. 80% Snapshot Backups Savings equal the portion of data set not changed since last copy was made. 46% RAID-DP Saves up to 46% versus mirrored data or RAID % FlexVol Thin Provisioning 20% to 33% typical savings. 80% Writable FlexClone Copies Savings equal size of original data set minus blocks subsequently changed in clone. Savings compound when using multiple features! 2008 Net. All rights reserved.
