This document discusses enterprise class storage and storage area networks (SANs). It defines enterprise storage as large-scale storage solutions designed for large organizations. It outlines different enterprise storage options like direct-attached storage (DAS), network-attached storage (NAS), and SANs. SANs are described as using fibre channel fabrics to connect storage devices directly to servers to enable high-speed data transfers. The document compares SANs to NAS and provides pros and cons of each approach. It also compares features of SAN storage equipment from vendors like IBM, EMC, and Sun/Oracle.

- 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. 3
- 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. 5
- 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 6
- 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 8
- 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 13
- 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 15
- 16. Comparison of SAN Storage Equipment from different OEM’s FEATURES IBM DS8000 EMC Symmetrix Sun 9990V / 9985V Flexible Duration YES NO NO Published Industry Standard Performance Benchmarks (SPC-1 & SPC-2) Comprehensive Data Stripping helps significantly reduce performance problems YES NO YES YES Limited Limited Asynchronous Remote Copy design can reduce data loss YES NO UNKNOWN Efficient Use of Cache YES NO NO Self Encrypting Disks YES NO NO System is non-disruptively upgradable in place from smallest to largest configuration YES NO NO 16
- 17. Comparison of SAN Storage Equipment from different OEM’s 17 FEATURES IBM XIV EMC CLARiiON & Symmetrix Sun / Oracle 6000, 99xxV Virtualization Easy to manage System Management more complex & time consuming System Management more complex & time consuming Performance Handles Equal Workload Frequent Manual Tuning Required Frequent Manual Tuning Required Rebuild Time 30 min for 1TB disks More than1 Hour More than1 Hour Snapshots Up to 16000 Far Fewer Far Fewer Migration Built-in capability No comparable capability No comparable capability Costs Lower Higher Higher
- 18. Comparison of SAN Storage Equipment from different OEM’s FEATURES IBM DS4000/ DS5000 EMC CLARiiON Dynamic mode change for remote mirroring YES NO Multi path software included in base price YES NO Switched Disk Drive Architecture YES NO Call home autonomic service calling YES NO No additional fees for software maintenance YES NO Mix & Match all disk capacities within same disk drawer YES NO 8Gbps Fibre Channel Host interface card YES NO 18
- 19. 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. 19
