Rev. 5.32 HP Restricted 2

Objectives

• Identify HP StorageWorks enterprise file services and customer business needs

• Describe the business value of HP StorageWorks enterprise file services

• Describe HP StorageWorks enterprise file services features

Rev. 5.32 HP Restricted 3

Business challenges

• Don’t lock me into a

proprietary systems— I don’t want to be at the mercy of a single vendor

• My storage needs are rapidly increasing and I have fewer people to manage it.

• I want to leverage my investment—people, equipment, processes, etc.

File serving needs

• Scalability—buy what I need today and let me add when I want to

• High availability— support for mission-critical environments

• High-performance NFSfile serving needs

• Industry-standard solutions

I think I’m paying too much!

Business needs

Rev. 5.32 HP Restricted 4

Qualifying questions

• What would it mean to you to be able to increase your file service capacity and support large file systems, while maintaining data integrity regardless of hardware failures— all within your current SAN infrastructure?

• How much would your business profit if your remote offices could consolidate and centralize data in the data center and access that centralized information at LAN-type performance without having to invest in architecture?

Complete line of HP ProLiant Storage Servers

• Support for Oracle, SQL Server, Exchange, etc., with iSCSI Feature Pack software

• Application Storage Manager for radically simple storage management

Clustered Gateway• Scalability (bandwidth and capacity)• Availability (failover with complete data

integrity, multipathing)• Protocol support (NFS and CIFS)• Management and solution stack

WAN Accelerator • LAN file serving performance over the WAN• File and Exchange server consolidation • Eliminate backup issues

Bringing file serving availability, scalability, and performance to HP storage solutions

HP StorageWorks Enterprise File Services Clustered Gateway

Availability• All nodes monitor health • Fully transparent failover—preserve

client state information • Hardware failover from one failed

node to another happens in ~5 seconds

Scalability and performance• Additional nodes can be added for

nearly linear increase in performance

• Supports up to 16 nodes • No forklift upgrades

Storage scalability • Customer can meet both storage and file

serving scalability needs• Snapshot integration with EVA storage

HP Clustered File System

Rev. 5.32 HP Restricted 7

HP StorageWorks Enterprise File Services Cluster—optimized scalability & availability

Traditional NAS / filer design

Multiple paths:No bottleneck

Symmetrical cluster file system

Bottlenecks: Metadata server

and Hot Spots

Distributed file system and metadata server designs

Scale-out: Scales to two nodes Scales to many nodes Scales to 16 nodes

Performance: Limited — requires distinct file systems for each node. Clustering is for HA not performance

Metadata bottlenecks and hot spots can cause problems as they are scaled out

Performance increases linearly as scaled out

Availability: Traditional clustering prone to error, downtime

Requires redundant data, storage, and servers

Built into shared data and shared storage design

HP StorageWorks Clustered Volume Manager Software (optional)

Improve storage utilization across cluster • Collapse storage silos into a single

higher utilized storage pool• 16TB per file system• Concatenation or striping of LUNs

Optimize for price:performance. • Use many cost-effective arrays/LUNs

instead of single expensive array• Stripe across many arrays/LUNs for best

performance

Flexibly manage storage across your business• On-line volume growth• Single shared pool of data to provision,

manage, and backup

• Group• Stripe• Expand online

HP StorageWorks Enterprise File Services (EFS) WAN Accelerator• IT appliances built on HP ProLiant

platforms• Deployed in remote site and data

center• Accelerates CIFS, NFS, HTTP,

FTP, MAPI• Transparent to clients and servers

(in-band or out-of-band)• Failthough capability for in-band• Utilizes:

– Caching– Best-in-class compression– Latency optimization– Predictive traffic analysis

• Replaces need for replicating data sets around the network and enables consolidation to central site

• EFS WAN Accelerator Manager to configure and monitor all nodes across enterprise

EFS WAN Accelerator value propositionTarget customers

Large enterprises (>10,000 employees) with a high percentage of workforce distribution across branch office and field office structure (for example, global financial services, retail, healthcare, services companies)

Value proposition

• Provides enterprise CIOs with a significantly higher degree of control over infrastructure assets

• Higher degree of centralization and control over information assets to more easily comply with Sarbanes-Oxley

• Estimated 30–40% reduction in TCO from: • Server/storage/client consolidation and resource optimization• Reduced labor intensive support/maintenance costs• Decreased facilities costs

Solution components

•Potentially new virtualized datacenter infrastructure•Potentially new thin client architecture•NAS•WAN appliance running file cache in branch offices•C&I•Managed services
