Mastering ATA over Ethernet

At one point in time, when you wanted to attach an external block storage device to a server, you mapped it as a Logical Unit (LU) across a Storage Area Network (SAN). In the early days, you would do this over the Fibre Channel (FC) protocol. More recently, iSCSI (SCSI over IP) has usurped FC in most data centers. more>>

Low Power Wireless: 6LoWPAN, IEEE802.15.4 and the Raspberry Pi

The Internet of Things (IoT) is one of the new kids on the block.

Hodge Podge

For every article, I try to write something that is interesting, entertaining, educational and fun. Sometimes I even succeed. Many other times I have some things I'd like to talk about, but there's not enough of it to fill the space. This time, I decided a disjointed hodge podge would be the theme. So let's just have a virtual nerdy talk about stuff, shall we? more>>

Papa's Got a Brand New NAS

It used to be that the true sign you were dealing with a Linux geek was the pile of computers lying around that person's house. How else could you experiment with networked servers without a mass of computers and networking equipment? If you work as a sysadmin for a large company, sometimes one of the job perks is that you get first dibs on decommissioned equipment. more>>
