SAN Pros and Cons ✔ Block level access to storage ✔ Highly scalable ✔ High performance for large block transfers ✔ Excellent availability through multiple paths ✔ Sharing of consolidated storage ✔ High-speed LAN-less or server-less backups ✔ Data sharing through proprietary filesystem solutions ✖ Expensive to deploy and manage ✖ Expensive HBAs (compared to NICs)

When SAN is appropriate ■ Parallel Databases — Decision support systems — Data mining — CRM — ERP ■ High bandwidth streaming video ■ Process intensive applications — Billing

Typical Network Attached Storage(NAS) Implementation

Server Consolidation. 13

NAS Pros and Cons ✔ File level access to storage ✔ High performance for small block transfers ✔ Data sharing through proven standard network

protocols (NFS, CIFS, HTTP), heterogeneous system environment

✔ Availability through high bandwidth clustering and

data replication

✔ Simple and inexpensive to deploy - inexpensive NICs ✖ Limited security ✖ Difficult to manage large installations ✖ Must overcome scalability and availability limits of direct attached storage devices

14

NAS Implementation ■ Network Attached Device — Integrated storage and server function — Smaller configurations ■ Server Attached Storage — Generalized file server function — Can be optimized for storage access only — Uses I/O interface for storage attachment — e.g. HP N4000, IBM RS/6000 S80

■ Network Appliance — Reduced server functionality for storage only — Server and storage integrated and often in same device — Optimized for file server — e.g. F820/840, IP4700 ■ Intelligent Network File

Servers

— Only used for file serving — Storage functionality is done by the storage subsystem

EMC NAS Value Proposition: NAS, SAN, or Both? SAN (Connectrix)

NAS (Celerra/IP4700)

■ Generally, Where You’d ■ File Serving Consolidation

Implement a Direct Attached Architecture

■ Databases (eg. Oracle) ■ Most Applications (eg.

SAP)

■ Share Info Among Hosts ■ File Serving Applications — Web Hosting (eg. InfoWeb) — Web Email (eg. USAnet) — Engineering (eg. Lucent)

■ SAN Backup

Remember, EMC Offers Both NAS & SAN… ...Best of Both Worlds 34

connectivity to LAN/WAN systems normally through TCP/IP Server

Summary: NAS vs. SAN NAS ■ LAN connectivity

(Ethernet/GbE NIC) ■ Part of a LAN & LAN over

WAN ■ Shares files, objects &

data ■ Object security through

network protocols ■ Paralleled on the network ■ Simple & easily configured ■ Operating System (OS)

independent

SAN ■ Fibre connectivity (Fibre

HBA) ■ Part of a server cluster ■ Shares data blocks &

volumes ■ Data security through

trusted servers ■ Switched to servers ■ Clustered storage ■ Fast, dedicated

infrastructure for backup 36

Benefits of Networked Storage ■ Lower costs of administration — Centralized management of storage — Resource sharing ■ Faster growth — Improved scalability, flexibility ■ Better IT services — Increased reliability and availability ■ Traditional battle: SAN vs. NAS — But both types of services are needed! ■ Storage utility model
