1 Make Your Existing File Storage Infrastructure Cloud-Ready Chuck Wood Director, Product Management F5 Networks

2 2 Agenda What is cloud storage? Technical barriers to using cloud storage Getting ready for cloud Options for integration Use Case Examples Summary

3 Introduction

4 Performance 4 Cloud in a Tiered Storage Framework Single Namespace Inactive and Unchanging Active and Changing Optimized Storage (Deduped SATA) Traditional Tier 2 (High-cap SATA) Traditional Tier 1 (High-perf FC, SAS) Memory Storage (Flash, DRAM) Cloud Storage (Public, hybrid, private) Cost

5 5 Comparing Performance General guidelines: Type of Storage Aggregate Bandwidth Single Operation Latency Local Tier 0 (SSD) Local Tier 1 (SAS) Local Tier 2 (SATA) > 1000 MB/s < 500 µs 500 MB/s 0.5 to 5 ms 100 MB/s.5 to 15 ms Cloud.1-10 MB/s 10 ms to >10s

6 6 Strong Interest in Cloud Would you consider private cloud as an alternative to traditional NAS Storage? 70% 60% 50% 40% 30% 20% 10% 0% Yes No Source: F5 Networks, July 2010

7 7 What Is Cloud Storage? No consistent definition For our purposes today, cloud storage is: Remotely accessed Optimized for long-term retention Not natively presented as a file system Might be rented (bought as a service) or owned (deployed conventionally)

8 8 Comparing Cost General guidelines: Characteristic Own Tier-1 Own Tier-2 Rent Cloud Purchase price ($/GB) $10 $2 - Rental cost ($/GB-Month) - - $0.15 HW/SW Maintenance (% of price over 36 months) Power and cooling costs ($/GB over 36 months) Effective Cost Per GB Over 36 Months 100% utilization; 0% access Effective Cost Per GB Over 36 Months 50% utilization; 0% access 15% per year 15% per year - $1.8 $0.2 - $16.30 $3.10 $5.40 $32.60 $6.20 $5.40

9 9 Own or Rent A Simple Model Profile for renting storage Low storage utilization today Modest total capacity Temporary peaks in storage demand Profile for owning storage High storage utilization today High total capacity Willing to deploy cloud-like technology in place of traditional NAS Storage capacity demand continually grows

10 Challenges

11 11 Goals and Constraints What users care about: No change to how they access files Having a single location for accessing files Maintaining a reasonable level of performance What IT cares about: Managing growth Improving utilization Reducing costs Reducing overall complexity Ensuring data security Maintaining data availability Meeting regulatory compliance requirements

12 12 Challenges and Solutions Challenges Maintain transparent access to files Solutions Data redirection within the file server File virtualization above the file server Move appropriate files to and from cloud Remote storage latency Data security Automatic classification + policy + migration Manual Only store inactive data in cloud Locally cache all file metadata Locally cache all file data 100% data and metadata encryption before leaving customer site Different storage model File system gateway to cloud API

13 13 Challenges and Solutions Challenges Maintain transparent access to files Solutions Data redirection within the file server File virtualization above the file server Move appropriate files to and from cloud Remote storage latency Data security Automatic classification + policy + migration Manual Only store inactive data in cloud Locally cache all file metadata Locally cache all file data 100% data and metadata encryption before leaving customer site Different storage model File system gateway to cloud API

14 Integration

15 15 Two Options for Integrating the Cloud Users and Applications Users and Applications File Virtualization File Server Redirection Gateway NAS

16 16 Understanding File Server Redirection Foo.txt file (metadata + data) Users and Applications Foo.txt file (metadata + pointer to data) Foo.txt data

17 17 Understanding File Virtualization Foo.txt file (virtual) Users and Applications Foo.txt file (physical) Foo.txt file (metadata + pointer to data) Foo.txt data File Virtualization Tier 0 Tier 1 Cloud

18 Use Case Examples

19 19 Building an Internal Cloud File Virtualization Applications and Users Tier 1 Tier 2 Tier 3 Create your own storage services: Use existing systems Manage internally Provision capacity to users and business groups Benefits: Seamlessly scale with growth; capacity on-demand Automatically blend storage types to meet individual needs Improve utilization rates and agility Organizational economies of scale for greatest cost control

20 20 Building an Internal Cloud Applications and Users Create your own storage services: Use existing systems and cloud Manage internally with cloud Provision capacity to users and business groups File Virtualization Benefits: Seamlessly scale with growth; capacity on-demand Automatically blend storage types to meet individual needs Improved utilization rates and agility Leverage cloud for long-term retention, archive, backup / DR Tier 1 Tier 2 Cloud Tier 3

21 21 Private Cloud: Tiering over the WAN Remote Locations Local Tier 1 Local Tier 1 Local Tier 1 Tier 2 Central Datacenter Remote file tiering Keep active files near users Migrate inactive data to a central location Benefits: Reduce storage footprint at remote locations Apply economies of scale for storing the majority of data Centralize management for better operational efficiency Better backup / DR management

22 22 Public Cloud: Tiering over the WAN Remote Locations Local Tier 1 Local Tier 1 Local Tier 1 Tier 2 A B Remote file tiering Keep active files near users Migrate inactive data to a central location and/or cloud Benefits: Reduce storage footprint at remote locations Leverage Public Cloud Storage Services for operational efficiency Better backup / DR management Public Cloud Storage Services

23 23 Summary Cloud storage technology is an attractive choice for long-term storage of files Important to understand cloud technology Independent of the options to deploy (rent/buy) There are two options to integrate cloud storage with existing file storage environments Best option will depend on your environment and data storage requirements Cloud storage technology enables advanced data management Example: Centralized Data Management
