Managing Server In A Distributed Data Centre (2)

Flexible, Scalable and Cost Effective.
The dynamic nature of the distributed data centre and cost constraints demands any remote server management solution to provide flexibility and scalability as part of the solution, without requiring the purchase of additional elements. A distributed solution should provide:

• No special software licenses to buy or maintain (client software, remote users, etc.)
• No special cabling limitations (supports CAT5 cabling)
• No special hardware or dongles to purchase and install
• Incremental ‘add-as-you-grow’ capability with no sudden cost increase to scale and add additional servers or remote administrators
• No conflict with existing server management solutions (no ‘rip-and-replace’)
• Ability to enhance existing server management solutions (local KVM)
• Ability to integrate into larger remote (OOBI10) management architecture 10 Out Of Band Infrastructure

Fault Tolerant and Secure.
Distributed remote assets must be fault-tolerant and secure by providing the following benefits:

• Allows management access when server, OS, or network stack is compromised
• No single point of failure (e.g. unit failure doesn’t effect other systems)
• Designed for high MTBF (Mean Time before Failure) (e.g. no moving parts, cooling fans, power supplies)
• No special security software or infrastructure to purchase, install and maintain
• Uses existing IT security services (RADIUS, LDAP, Active Directory)
• Optional out-of-band access in case of network failure (e.g. serial modem access)

Managing Server In A Distributed Data Centre (1)

In the distributed data centre, there are many elements to consider when developing an overall server IP-based KVM management strategy. Guaranteed Anytime Anywhere Access.

A server management solution should support guaranteed access (anytime, anywhere) to servers regardless of how many users are logged in. Criteria to look for include:

• Secure administrator access to servers over an IP network - from LAN or the Internet
• Non-blocked access to servers (e.g. no conflict for remote access)
• BIOS level access to servers
• No limitations on locations of servers (across the room, across the globe)

Simple and Non-Invasive.
Any server management strategy should reduce complexity and lower the overall IT workload. Deployment, installation and usage of a server management solution should minimize or eliminate impact on the server, its operating systems, services and applications. The solution should offer:

• Simple and quick installation
• No special hardware (management cards, etc.) to install in server
• No special software (drivers, application software) to install and maintain on server
• Operating system and application independent
• Simplified remote maintenance (e.g. Virtual Media support)
• No special software to install and maintain on clients
• Small size (form factor)
• Minimal power consumption and heat generation
• Flexible cabling (utilize CAT5 cabling)
• No special training required to install or operate
