Recommended:
• RAID 10 – Recommended for enterprise web server solutions where availability and
redundancy and performance are the highest priority, usually for stand-alone portal sites
that are critical to the organization’s business.
• RAID 5 – Recommended for web servers that require maximum storage capacity and
moderate data protection and performance.
• RAID 6 – Recommended for web servers that require maximum storage capacity and
enhanced data protection and performance.
• RAID 50 – Recommended for those solutions that require a balance between storage
capacity and performance.
• RAID 60 – Recommended for those solutions that require a balance between storage
capacity and performance with enhanced data protection.
• RAID 0 – Recommended for solutions where the web server will be part of a group of web
servers that service a large internet portal and performance is the highest concern. In this
situation, availability and redundancy are addressed by the cluster group and do not need
to occur at the disk level.
• RAID 1 – Good solution for small websites which do not require high storage capacity.

Database or Online Transaction Processing Servers
Database servers can range from simple workgroup databases like Microsoft
®
Access
™ with a few
hundred users to critical Enterprise databases like Oracle or SQL Server with thousands of
users. Database applications will always benefit from some data protection while other
requirements, such as performance and availability, will vary. As a general rule, the more critical
the database, the greater the need for data protection. Additionally, the performance requirements
increase relative to the number of users accessing the database.
