Presentation on theme: "11 HITACHI NAS REPLICATION OVERVIEW NOVEMBER 2013."— Presentation transcript:


2 2 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

3 3 SEVERE RAMIFICATIONS OF DATA LOSS Data unavailability results in lost revenue and possibly business failure 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).

4 4  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 DELIVERS MULTIPLE BENEFITS REPLICATION IS THE ANSWER

5 5  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 HNAS HAS THREE REPLICATION MECHANISMS AVAILABLE HITACHI NAS REPLICATION CHOICES

6 6 OBJECT REPLICATION IS USUALLY BEST Object Replication: Fast and Efficient File Replication: Granular Block Replication: Powerful Data Object Data Object Data Object Data Object Data Object Data Object Data Object Data Object Data Object Data Object Data Object Data Object Ideal for DR and data migration when backup windows are smaller Up to 2.8 times faster than file replication on full file replication Eliminates traversing directories and files for small changes No wasted empty containers sent Only tracking incremental changes Ideal for fine granularity Ideal for high availability configurations

7 7  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 HARDWARE ACCELERATED REPLICATION OBJECT LEVEL REPLICATION OVERVIEW HNAS Server File system B Replication Target File system A Replication Source Direction of replication Network Primary File Server DR File Server

8 8 HIGH PERFORMANCE OBJECT REPLICATION Test CaseFile 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!

9 9 ACHIEVE ZERO RTO BY LAYERING HA AND SYNCHRONOUS REPLICATION HOST Application Multi path Software Any External Storage UVM VSP/HUS Host paths VOL pair SVOL PVOL TrueCopy paths Quorum HOST Application Multi path Software UVM BLOCK REPLICATION FOR HIGH AVAILABILITY  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


11 11 REPLICATE ONLY THE FILES OR DIRECTORIES YOU REALLY NEED FILE REPLICATION FOR FINE GRANULARITY  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

12 12 CREDIT UNION AUSTRALIA SUCCESS STORY “To become the 5 th 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

13 13 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

14 14 9 of 10 Rate HDS replication software as effective or very effective in meeting requirements* 85% Users indicate positive ease-of-use experience * Source: TechValidate HDS Replication Use-case Survey October 2013 Excellence in Customer Service Awards from: HITACHI REPLICATION HIGHLY RATED

15 15 HNAS REPLICATION VALUE PROPOSITION  Hitachi NAS provides three powerful methods of replication to meet different data protection, high availability and/or disaster recovery needs  Benefits: ‒ Reduces data loss risks via proven enterprise-class replication technologies ‒ Delivers SLAs that are better aligned with business objectives ‒ Cost savings through: ‒ Lower network bandwidth requirements ‒ Reduced energy, cooling and space ‒ Simpler management and maintenance ‒ Increased uptime of mission critical systems
