Linux and other Unix-like operating systems use the term “swap” to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?

The Open Solaris Hardware Compatibility List shows systems and peripherals which are compatible with the Solaris / Open Solaris OS.


I’ve used VMWARE ESX / Xen paravirtualization, Virtuozzo, Solaris Containers, and FreeBSD Jails as os level virtualization. Virutalbox is another full virtualization solution. Presently, VirtualBox runs on Windows, Linux and Macintosh hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows […]


ZFS has amazing feature set and now it is ported to Mac ZFS file system developed by Sun for its UNIX operating system. ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of filesystems can draw from a […]


Project Indiana is working towards creating a binary distribution of an operating system built out of the OpenSolaris source code. The distribution is a point of integration for several current projects on, including those to make the installation experience easier, to modernize the look and feel of OpenSolaris on the desktop, and to introduce […]


This is an interesting filesystem comparison. If you are looking to build cheap storage for personal use file system decision is quite important: This is my attempt to cut through the hype and uncertainty to find a storage subsystem that works. I compared XFS and EXT4 under Linux with ZFS under OpenSolaris. Aside from the […]
