HITACHI NAS REPLICATION OVERVIEWNOVEMBER 2013

2

COMMON IT BUSINESS CHALLENGES

Protecting informationgiven 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

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).

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

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

OBJECT REPLICATION IS USUALLY BEST

Object Replication:Fast and Efficient

File Replication: Granular

Block Replication: Powerful

DataObject

DataObjectData

ObjectDataObjectData

ObjectDataObject

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

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

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

10

BLOCK REPLICATION MANAGEMENT

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
