Customer Background and Needs
　　A Beijing Internet Data Center's (IDC) WEB data platform was built on LINUX environment. Its major service is to provide real-time news/headlines/updates/periodicals/reports release and search functions. The platform was built using multiple conventional rack-mount servers. See diagram 1 below:

As Internet users and WEB visitors increase exponentially, this IDC approached a bottleneck in responding to these increasing users requests resulting in delayed response time to requests and poor service quality. A highly scalable, available and usable data platform was imminently required to coop with the increasing demands. The platform must be:
· Highly Scalable: when network load increases, the platform can be expanded without affecting service quality
· Highly Available: even though occasional hardware or software failures may occur, the platform must ensure 24 hours uptime
· Highly Manageable: convenience is key
· Highly Cost-Effective: total system cost should be economical

Galactic's Solution

After analyzing customer's actual needs, we have gathered the following short-comings in the conventional platform:
· complicated upgrade processes, need to interrupt service while changing parts causing unnecessary wastage of system resources
· high-end servers upgrades translate to high costs
· single point failure occurrence in conventional rack-mount servers quite common, a single hardware or application software failure may cause service interruption
As a result, Galactic offers a tailored solution utilizing our SuperBlade computing Systems which supports hyper-threading Intel Xeon as the hardware platform combined with LINUX LVS network clustering and storage sharing technologies. Through redeploying system configurations, the solution helped to increase total system performance, stability, manageability, and thus saving unnecessary costs.

Major Characteristics of Galactic's Solution:
· Using LINUX LVS network clustering and IP load balancing technologies, software redundancy was created to ensure system scalability, availability and optimized system performance on the network. Hot-swappable blades, power supplies, cooling fans, and I/O modules allows immediate and convenient system reconfiguration without affecting existing services
· Galactic's "Engine OS" intelligent management software helps users to realize real-time system monitoring and management
· Galactic's "High Expandable Internet Supercomputer" patented technology integrates two standard 64-bit PCI-X I/O slots (support any PCI standards) onto the back panel of each blade. Customers need not purchase extra I/O accessories but can utilize their existing resources which creates enormous cost-savings
· The flexible, state-of-the-art design of Galactic SuperBlade computing Systems facilitates scalability and upgradeability according to customer's actual needs

Total Effect
Under the concerted efforts of Galactic and our partner by utilizing the latest technologies and professional services, Galactic ensures the highest return on our customer's investments. The new platform increase total efficiency by at least 80% upon optimization of system softwares. The Internet Data Center subjected the existing and new platforms under web stress test in order to determine the difference in performance. Test results are as follows:

Internet Data Platform Test Results

Test Objective

To determine the response time by existing and new platforms under different web stress request conditions.

Test tools and Items
Method: Webserver Stress Tool (Indivdual User Edition)
Concurrent Users: 100
Test Items:
a. News web pages static browsing (100 concurrent users log-on to home page – browse news channel – browse an article)
b. search news dynamically (100 concurrent users log-on to news channel – search a key word)
c. call-up a web page dynamically (100 concurrent users log-on to news channel – search for a particular news within the last 10 days – browse the article
d. increase number of users gradually (gradually achieving 100 concurrent users log-on to home page – browse news channel – browse an article)
e. Users randomly browse home pages of different channels (100 concurrent users log-on to home pages – headlines – updates – periodicals – reports, etc.)

Test Results

Remarks: Galactic SuperBlade computing WEB platform (Diagram 2) consists of two SuperBlades computing with a blade used as a search engine. The conventional WEB platform (Diagram 1) consists of four PIII rack-mount servers with a double Xeon rack-mount server used as a search engine.
