Enterprise Class Storage

Enterprise storage is a broad category that includes productsand services designed to assist large organizations withsaving and retrieving digital information.

Enterprise storage can handle large volumes of data andlarge numbers of users.

It usually involves centralized storage repositories, suchas storage area networks (SANs) or network-attachedstorage (NAS) devices.

Enterprise storage can be broken down into severalcategories.

3

Enterprise Storage Networking and

Management

Enterprise storage devices utilize similar technology as

consumer and small business storage solutions.

Enterprise data storage generally offers higher reliability,

availability and scalability.

Expensive than consumer or small business storage

Requires more time & expertise to setup

4

Benefits of Enterprise Storage

On-Premises enterprise storage is that the organization retains complete

control of the hardware and data, satisfying some security and compliance

concerns.

Cloud-based enterprise storage simplifies storage management and may

lower costs in some cases.

Enterprise storage solutions is that they enable file sharing and collaboration

among workers.

Enterprise storage also offers better performance, reliability, availability and

scalability than other types of storage solutions.

It offers security features, such as user-based permissions, that aren't

commonly found in consumer storage solutions.

Enterprise Storage Vendors

HARDWARE VENDORS

DELL, HP, EMC, IBM, NetApp, Hitachi Data Systems, SanDisk; etc

CLOUD BASED VENDORS

Amazon Web Services, Windows Azure, Google, IBM, Rockspace; etc

OPEN SOURCE VENDORS

OpenAFS, FreeNAS, OpenSMT, Gluster, OHSM, Aoe Tools ; etc

6

STORAGE OPTIONS

Direct Attached Storage(DAS)

Network Attached Storage(NAS)

Storage Area Network (SAN)

7

Direct Attached Storage (DAS)

It is made of a data storage device connected directly to a

computer through a host bus adaptor

Computer Storage that is directly attached to the computer or

server, without a storage network

It can be internally & externally

It is dedicated to only one server, so cannot be shared between

other servers

It is connected to a LAN / WAN Network

Examples – Application Server, Print Server, Data Base Server,

NFS or CIFS Clients

8

DAS ADVANTAGES & DISADVANTAGES

ADVANTAGES:

Inexpensive

Faster for certain applications

Ease of Management and Administration

DISADVANTAGES:

Limited Sharing

Improper Capacity Utilization

Manageability for IT Managers

9

Network Attached Storage (NAS)

It is a computer connected to a network that only provides file

based data storage services.

Contains one or more hard disks, often arranged into logical,

redundant storage containers or RAID arrays devices on the

network

Usually used in places of dedicated file servers

Manufacturers of NAS are HP, NetApp, Dell, CISCO, Sun

Microsystems; etc

It is connected on a LAN Network

10

NAS ADVANTAGES & DISADVANTAGES

ADVANTAGES:

Performance

Cost Effective

Scalable

Manageability

DISADVANTAGES:

File Oriented

Slows down for video applications or multiple large files

Performance depends on the protocol

11

Storage Area Network (SAN)

SAN was introduced to meet the demands of the storage system,

increase the system efficiency & capacity expansion

It transmits data between storage and storage or storage and client

servers

It uses a Fibre Channel Fabric Topology

Data from multiple servers is stored is stored in dedicated areas

called “Logical Unit Number”

Facilitates direct High Speed Data transfers between servers and

storage devices

12

SAN Components

Host HBA

SAN Cables & Connectors – Multimode, Single

Mode, & Copper. ST, SC, LC

SAN Switches – Workgroup, Directors

SAN Zoning – Hard, Soft & Mixed

Zone Sets

Storage Arrays

13

NAS VS SAN

NAS SANFile Centric Data Centric

Dedicated File Server Server / Storage Independence

Data Sharing between heterogeneous servers Combines High Performance of I/O channel with

connectivity of a Network

Combines storage & Network on a single board

with a light weight File System KERNEL

Centralized data management

Beneficiary of explosion in web servers demand Server less backup & needs development in

many areas like standards, interoperability

14

SAN ADVANTAGES & DISADVANTAGES

ADVANTAGES:

Simplified storage administration

Ability to boot itself & expand the storage capacity

Low Cost of Storage Management

Instant & Real Time Information

Disk mirroring

DISADVANTAGES:

Poor Implementation results in performance bottlenecks

Difficult to keep backup of data in case of breakdown

More Expensive

CONCLUSION

SAN storage is the most appropriate option for BSS

Data Centre.

Sizing of storage needs to be done based on the

storage requirements for next 3 to 5 years.

Every OEM has a future roadmap and delivers better

products with better capacity at competitive pricing.
