EMC: The Virtual Data Center EMC: The Virtual Data Center Presentation Transcript

  • EMC: The Virtual Data Center Dejan Živanovi EMC Technology Solution Group Sr. Technology Consultant High-End platforms & Business Continuity © Copyright 2008 EMC Corporation. All rights reserved. 1
  • Business Challenges Data growing at 70% annually – 80% are files Data migrations consume time – Independent study of 250 companies 40% say migrations involve more than 5 people 60% say data is migrated weekly, monthly, or end of lease period 82% say migrations performed at night or on weekends to avoid downtime 60% spend more than 2 weeks planning for data migration Source: CeBIT – Delays effective use of newly purchased storage New applications, new versions Consolidation, rapid deployment, flexible infrastructures, complexity, costs, and quality of service Hardware underutilized or over utilized Virtualization is not an option, it is a requirement © Copyright 2008 EMC Corporation. All rights reserved. 22
  • The IT Infrastructure World is Changing from to Platform-centric Service-oriented Static Dynamic Procedural Web-based / Orchestration Physical resources Virtual environments Framework management Model-based management © Copyright 2008 EMC Corporation. All rights reserved. 3
  • Defining Virtualization Virtual Memory Each application sees its own logical memory, independent of the physical memory Virtual Networks Technology that enables logical Each application sees its own logical network, independent of the physical network representations of physical resources Virtual Servers Each application sees its own logical server, independent of the physical servers Virtual Storage Each application sees its own logical volume, independent of the physical disks © Copyright 2008 EMC Corporation. All rights reserved. 4
  • EMC’s Comprehensive Four Element Virtualization Approach Services – Design to achieve specific requirements – Complete plan, build, and manage support Consolidation – Infrastructure approach that extends the virtualization benefits and Virtualization Services Server (VMware) – Lower server costs and operational efficiencies – Increased flexibility and availability for servers and Server applications Virtualization – Speed of provisioning File (Rainfinity GFV) File Virtualization – Increased NAS flexibility and availability – Reduces storage and storage management costs Block (EMC Invista) Block Storage – Increased SAN flexibility and availability Virtualization – Non-disruptive migration © Copyright 2008 EMC Corporation.

  • VMware – Server Virtualization Basics Before Server Virtualization: After Server Virtualization: App App App App App App Application Operating system Operating system Operating system Virtualization layer Single operating system image per Virtual Machines (VMs) break machine dependencies between operating system and hardware Software and hardware tightly coupled Manage operating system and Running multiple applications on same application as single unit by machine often creates conflict encapsulating them into VMs Underutilized resources Strong fault and security isolation Hardware-independent: They can be provisioned anywhere © Copyright 2008 EMC Corporation.

  • File-Level Virtualization Basics Before File-Level Virtualization After File-Level Virtualization IP network IP network NAS devices/platforms NAS devices/platforms Every NAS device is an independent Break dependencies between end-user entity physically and logically access and data location Underutilized storage resources Storage utilization is optimized Downtime caused by data migrations Non-disruptive migrations © Copyright 2008 EMC Corporation.

  • Rainfinity Global File Virtualization Optimize NAS Devices while Increasing Service Levels Typical Customer Pain Points File servers/NAS device utilization – Over-utilization affects performance—under-utilization costs money Protecting critical files FS1 FS2 FS1 FS2 – Are they included in information protection strategy Global namespace Migrations are complex – Can be disruptive and time-consuming IP Rainfinity EMC Rainfinity Value Minimizes system and network bottlenecks – Identifies poor utilization and enables rebalancing – Integrates file archiving with virtualization Multi-vendor NAS Simplifies and eliminates disruption during migrations/tech refreshes EMC Rainfinity Advantages – Provides non-disruptive read/write Standards-based architecture supports heterogeneous, multi-vendor environments Cost-effectively protect critical files Integrated applications to identify and optimize utilization and performance – Synchronous file replication over IP networks Enterprise scalable architecture © Copyright 2008 EMC Corporation. All rights reserved. 10
  • Optimizes Network Storage Capacity Identifies and Rebalances Poor Utilization Before: Too many servers – Buying more servers for additional storage Poor resource utilization – Overutilization affects performance – Underutilization costs money Rainfinity IP network Global File After: Virtualization Identifies areas of poor resource utilization Rebalances capacity No need to buy more servers for Optimal additional storage Utilization 1 2 3 4 5 6 Servers © Copyright 2008 EMC Corporation.
