(Jan 8, 2009, 23:04 UTC) (741 reads) (0 talkbacks) (feedback)
Enterprise Networking Planet: "The Sun x4500 series storage servers have been a big hit. You get 48 disks, and ZFS takes advantage of the large number of disk spindles to achieve amazing throughput. Here's another great use for the x4500: host all your virtual machines on it and share them to your Linux clients via iSCSI. We'll show you how."

The Best Open Source Alternatives to MS Exchange
(Dec 20, 2008, 20:03 UTC) (5514 reads) (6 talkbacks) (feedback)
Intranet Journal: "No matter what you might happen to think of it, the fact of the matter is that we live in a Microsoft- driven enterprise environment. Whether this is for better or for worse, the fact is that some legacy ways of doing things are just so embedded, than even attempting to try an alternative is laughable. All of that being said, I believe that enterprise-level groupware functionality is not one of those legacy applications. In short, I believe in groupware offerings outside of the halls of Microsoft. And it is in this spirit, that I will now take on the task of creating a list of the best open source alternatives to Microsoft Exchange."

Tables can be partitioned based on range (column values in a given range), list (column values matching a set of values), hash (user defined hash based on column values) or key (predefined hash function based on column values). Each partition can have different data directory."

Scale Your File System With Parallel NFS
(Nov 13, 2008, 06:04 UTC) (2734 reads) (0 talkbacks) (feedback)
IBM Developerworks: "The Network File System (NFS) is a stalwart component of most modern local area networks (LANs). But NFS is inadequate for the demanding input- and output-intensive applications commonly found in high-performance computing—or, at least it was.
