2. 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.

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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
MiB/s
1 hr, 39 m, 33 s
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. 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

10. Block Replication Management

11. 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
