3. Enterprise Class Storage
 Enterprise storage is a broad category that includes products
and services designed to assist large organizations with
saving and retrieving digital information.
 Enterprise storage can handle large volumes of data and
large numbers of users.
 It usually involves centralized storage repositories, such
as storage area networks (SANs) or network-attached
storage (NAS) devices.
 Enterprise storage can be broken down into several
categories.

4. 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

5. 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.

6. 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

7. STORAGE OPTIONS
Direct Attached Storage(DAS)
Network Attached Storage(NAS)
Storage Area Network (SAN)
7

8. 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

9. 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

10. 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

11. 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

12. 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

13. 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

14. NAS VS SAN
NAS SAN
File 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

15. 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
