&gt; We went to Fry's an he bought the 200GB Seagate drive that they  
&gt; have on sale.
&gt;
&gt; After he connected everything up it only took me about 15-20  
&gt; minutes to bring the drive on line.
&gt; I'm running Suse 9.3 pro, with 2.6.11.4-21.7-default kernel.  It  
&gt; already has the aoe module in the library.
&gt; His home system is a Mandrake 10.1 with 2.6.8... kernel and it does  
&gt; not have aoe.
&gt;
&gt; Formatting the drive appeared to take about the same amount of time  
&gt; as if it was installed internally.
&gt;
&gt; Once formatted and mounted I ran a few tests to see what the  
&gt; performance was like. My network in 10/100Mb fdx.
&gt; I tried copying files of various sizes and directories with a mix  
&gt; of files in them, noting the times.
&gt; I then repeated the same to a local drive and then to a local drive  
&gt; on a different controller.
&gt;
&gt; The copies to the aoe drive and to the internal drive on another  
&gt; controller were within a few percent (~10) of each other.
&gt; The copy to another drive on the same controller was about 20%  
&gt; slower than the other two.
&gt;
&gt; I imagine that using their SATA board (available shortly) that  
&gt; supports Gig-E connection will be much faster.
&gt;
&gt; If you get their shelf with multiple drive trays you can software  
&gt; raid or LVM to configure the drives  however you would like.
&gt;
&gt; The eval units are expensive, $300 without drive, but for business  
&gt; uses the shelf unit with multiple drives appears to be cost effective.
&gt;
&gt; There was an article in the June 2005 issue of Linux Journal that  
&gt; does a very good job of describing how it works.
