Hitachi NAS replication overview November 2013 1

Common IT business Challenges 4/5/2017 Common IT business Challenges Protecting information given exploding data growth Delivering a powerful and highly available infrastructure Balancing desired data protection RPO and RTO with costs and budgets Understanding and preparing for all types of disasters and outages Testing and assuring disaster recovery plans Presenter: While these bullets are great discussion points, be sure to ask audience for feedback and conversation around any pain- points that might exist in addition to these bullets. Use the results of that conversation to tailor this presentation and focus the time around the admitted pain points. After discussing each briefly ask the audience for feedback. Do they agree with the list? Are there things that should be added? What are the focus areas within this prospect from this list? You can then use gathered information as a basis for to schedule follow- up discussions around the problem. Avoid prescribing a solution before you have all the information you need about your specific customer’s view of problems.

Severe ramifications of data loss 93% of companies that lost the use of their data center for 10 days or more filed for bankruptcy within one year of the disaster (Source: National Archives & Records Administration, Washington D.C.) Of the companies experiencing disasters, 43 percent never reopen, and 29 percent close within two years (Source: McGladrey & Pullen, LLP). The average cost of downtime as a function of labor (for large organizations) is $1,010,536 per hour (Source: Meta Group Study). A service interruption could cost a company (Bank) between $60,000 and $250,000 a minute (Source: U.S. Banker). Data unavailability results in lost revenue and possibly business failure

Replication is the answer Hitachi NAS replication delivers multiple benefits High Availability Fault-tolerant, failure-resistant streamlined infrastructure with affordable cost foundation Continuous Operations Non-disruptive backups and system maintenance coupled with continuous availability of applications Disaster Recovery Protection against unplanned outages such as disasters through reliable, predictable recovery

Hitachi NAS Replication choices HNAS has three replication mechanisms available File Level Replication NDMP based data copy of files Walks directory tree to build delta/incremental Block Level Replication Leverages underlying storage replication technology Enables High Availability and advanced replication scenarios Object Level Replication Only replicates objects changed since last checkpoint Results in faster, more efficient replication

Object Replication is usually best Ideal for DR and data migration when backup windows are smaller Up to 2.8 times faster than file replication on full file replication Ideal for fine granularity Object Replication: Fast and Efficient File Replication: Granular Block Replication: Powerful Data Object Only tracking incremental changes Ideal for high availability configurations Eliminates traversing directories and files for small changes No wasted empty containers sent

OBJECT Level REPLICATION Overview High Performance Hardware Accelerated Replication HNAS Server File system B Replication Target File system A Replication Source Direction of replication Network Primary File Server DR File Server Snapshots on source have equivalent snapshot on target Target file system is not mountable unless promoted Multiple node clusters can replicate to a single node cluster or one cluster can replicate to multiple clusters

HIGH PERFORMANCE OBJECT REPLICATION Test Case File Level Replication Object Level Replication Performance Improvement Full replication of 40,000 large files (100 MiB) 4 hrs, 35 m, 3 s 242.38 MiB/s 1 hr, 39 m, 33 s 669.70 MiB/s 2.8 times faster Full replication of a large number (8,000,000) of small files (4 KiB) 38 m, 20 s 3,478 files/s 20 m, 13 s 6,595 objects/s 1.9 times faster Delta replication (16%) of a large number (8 million) small files (4 KiB) 59 m, 2 s 361 files/s 2 m, 16 s 9,412 objects/s 26 times faster!

Block Replication for High Availability 4/5/2017 Achieve Zero RTO by layering HA and Synchronous replication Concept Continuous availability solution in a local or remote site Configuration Mirrored internal and external data and controller Benefit Eliminate business impact associated with applications downtime Applications can run continuously despite unplanned outage of storage (and/or controller) Simplified and non-disruptive migrations to next-generation controllers HOST Application Multi path Software HOST Application Multi path Software Host paths VSP/HUS VOL pair VSP/HUS PVOL SVOL TrueCopy paths UVM UVM Quorum Any External Storage

Block Replication Management

File Replication for fine granularity 4/5/2017 Replicate only the files or directories you really need Concept Specifically chose which files and/or directories you wish to replicate Benefits Eliminates time and resources wasted on replicating unneeded files or directories Allows informed decisions on what to replicate Ability to exclude temporary files or parts of a file system that hold no business value Substantially reduces the amount of data sent from the source machine Decreases the storage requirements of the destination system

Credit union australia success story “To become the 5th pillar of the Australian banking system and compete with bigger players in the industry, our organization is going through a major transformation. The platform upgrade was business-changing.” David Gee, Chief Information Officer, Credit Union Australia challenges Data center required an upgrade to enable sustainable growth Need for big-bank platform quality and power on a scalable and flexible model, to effectively compete with the “big 4” banks Hds solution Hitachi Virtual Storage Platform Hitachi Unified Storage Hitachi Content Platform Hitachi NAS Platform results Ability to replicate all its data securely and safeguard against disaster situations Flexibility of replication service with responsiveness that could maintain availability at 99.98% Ability to scale and react to business demand

PRECISION DISCOVERY Success Story “A big reason we’ve stayed with Hitachi all these years is its people: The willingness and expertise from Hitachi engineers, sales, field and support keep us coming back. They have earned our complete trust and loyalty.” Howard Holton, Director of IT Precision Discovery challenges To provide high caliber service while offering innovative technology & expert consulting Ability to alleviate the typical challenges of e- discovery Hds solution Hitachi NAS Platform 3090 & 3080 Hitachi Unified Storage Hitachi Compute Blades 320, 500 & 2000 Hitachi Content Platform results Ability to manage 2PB of storage Reclaim storage in the environment, & reduced operational expenses Ability to handle data reduction, deduplication, replication & compression

Hitachi Replication Highly RATED 9 of 10 Rate HDS replication software as effective or very effective in meeting requirements* 85% Users indicate positive ease-of-use experience RATED HIGHLY BY HDS USERS Finally, at the end of the day, the proof-point and what matters most are satisfied customers And that HDS solutions effectively deliver results as required by users Actual statistics from a customer survey provides validation of the quality of our data protection replication products We have also been recognized for excellence in customer service, which is very important to us as a business HDS has been praised by Bank of America and SBC and we have also won a “Supplier Excellence” award from Texas Instruments There are many other awards Hitachi Data Systems has received which are not listed in this slide, including one from a large auction company that starts with an “e” Excellence in Customer Service Awards from: * Source: TechValidate HDS Replication Use-case Survey October 2013
