Reference

Host: CentOS 5.6 & 6.0 x86_64
RAID controller: ARC-1880IX-24

Setup hardware RAID volume(s) using RAID BIOS. (Tab/F6 at booting)

If CentOS was installed without Areca driver, follow these steps:
yum install gcc-c++ kernel-devel make
Download source tar ball from http://www.areca.com.tw/support/s_linux/linux.htm
Unzip and cd into it
make
chmod u+x arcmsr.ko
insmod arcmsr.ko
Use fdisk -l to verify the RAID volume(s) are visible.
Use fdisk/gparted(provided by EPEL repo) to create partition table and manage logic volumes.

Google Analytics API

To retrieve the report data:
DataQuery q = new DataQuery(new URL("https://www.google.com/analytics/feeds/data"));
q.setMaxResults(8192);
q.setStartDate("2007-01-01");
q.setEndDate("2012-12-31");
q.setDimensions("ga:pageTitle,ga:pagePath");
q.setMetrics("ga:pageviews,ga:entrances,ga:avgtimeonpage");
q.setSort("-ga:pageviews");
q.setIds("ga:" + profileId);
DataFeed dataFeed = client.getFeed(q, DataFeed.class);
for (DataEntry entry : dataFeed.getEntries()) {
  // Do something with entry
}

The profileId could be listed by:
ManagementFeed f = client.getFeed(new URL("https://www.google.com/analytics/feeds/datasources/ga/accounts/~all/webproperties/~all/profiles"), ManagementFeed.class);
for (ManagementEntry entry : f.getEntries()) {
  System.out.println(entry.getProperty("ga:profileId"));
}

A list of Dimensions and Metrics could be found at http://code.google.com/apis/analytics/docs/gdata/gdataReferenceDimensionsMetrics.html.

Google Analytics API Notes

A general way to query Google Analytics API:

String feedUrl;

feedUrl = "https://www.google.com/analytics/feeds/datasources/ga/accounts";

feedUrl = "https://www.google.com/analytics/feeds/datasources/ga/accounts/~all/webproperties";

feedUrl = "https://www.google.com/analytics/feeds/datasources/ga/accounts/~all/webproperties/~all/profiles";

URL queryUrl = new URL(feedUrl);

ManagementFeed feed = client.getFeed(queryUrl, ManagementFeed.class);

for (ManagementEntry entry : feed.getEntries()) {

  System.out.println("--- Account Entry ---");

  for (Property property : entry.getProperties()) {

    System.out.println(property.getName() + ": " + property.getValue());

  }

}
