* Raid system with iSCSI connected to the two (optimally all three)
  number crunchers which are exporting the data to the other hosts via
  NFS. (eSATA any good?)

* an actual machine (2-4 cores, 2-4GB RAM) with hardware raid (~24*1TB)
  serving the files AND doing the backup (e.g. one raid onto another
  raid on these disks) 

* A storage solution using fibre-channel to the two number crunchers.
  But who does the backup then? The oldest number cruncher might be
  able to handle this nightly along with some computing all day. But it hasn't
  got the disk space right now.

Potentially Unwanted Software

If you remove or disable "spyware", "adware"  and other potentially
unwanted software ("potentially unwanted software"), it may cause
other software on your computer to stop working, and it may cause you
to breach a license to use other software on your computer (such as
where the other software installed the potentially unwanted software
on your computer as a condition for your use of the other software).
By using the features of the service intended to help you remove or
disable potentially unwanted software, it is possible that you will
also remove or disable  software that is not potentially unwanted
software. If a feature of the service prompts you before removing or
disabling potentially unwanted software, you are solely responsible
for selecting which potentially unwanted software the service removes
or disables.  Before authorizing the removal of any potentially
unwanted software, you should read the license agreements for the
potentially unwanted software.

Hello Mike,

How are you? I hope everything has been well for you and Linux
Gazettein 2007. With the end of the year approaching I would like
Linux Gazette to consider spending a portion of your remaining budget
on stock photography from [SITE].

As you may already know [SITE] offers high quality royalty free images
for as little as $1.  It is the perfect solution for art directors,
graphic artists, and marketing professionals looking for creative
royalty free imagery to illustrate such things as magazine ads,
websites, billboards, flyers, and presentations.

Our images are collected from some of the top photographers and
artists around the world, actually over 60,000 of them. With this huge
collection of talent we have built an amazing database of 2.7 million
royalty free images covering all types of categories, subjects, and
themes.

Selling "High Quality" images at $1 might sound unbelievable, and
possibly illegal. But I assure you [SITE] does offer beautiful and
legal images at prices starting from $1. So check us out today! [SITE]

If you no longer wish to receive these emails, or you wish to update
your profile, please click here.
