bits and pieces.
I haven't had a decent Sun machine for a few years so am looking
forward to this one.
I did have an Ultra 2 with dual 400 procs and it was my main machine
for a good few years.
Ohhhh my. :) You are going to LOVE your new machine, then. I've
always loved the Ultra2; it's one of Sun's finest workstations. The
UltraSPARC-II processor is a good design...but the UltraSPARC-III
kicks the snot out of it. It's a whole different world.
For about a year until a recent upgrade, I ran the following on a
dual 900MHz UltraSPARC-III+ machine with 4GB of RAM and native FC
disks, a Sun Fire 280r:
- Eleven virtual machines (using Solaris "Zones" virtualization
system)
- An email server for about 100 people, comprising:
= Incoming SMTP, 50K-70K messages per day, ~91% spam
= Spam filtering (heavy REGEXP processing)
= Virus scanning, for those few still running Windows
= POP3, IMAP, and IMAPS spool access
- Two web servers handling about thirty virtual hosts, most PHP-based
- Network monitoring system
- Real-time NEXRAD weather imagery processing system
- A biggish (20 queries/sec) database server
- Three Sun Ray thin client terminals (often running Firefox,
Thunderbird, etc)
- All of my software development (editing, compiling, testing)
...All on a SINGLE 4U rackmount machine with two 900MHz UltraSPARC-
III+ processors (8MB L2 cache each) and 4GB of RAM. It was a bit
swappy with only 4GB (450 processes in the process table, "ps" output
scrolls and scrolls), but very responsive. I recently upgraded it to
a dual 1.2GHz UltraSPARC-III+ machine with 8GB of RAM.
Show THAT to an x86 fanboy and watch the pimply jaw drop. ;)
I was looking at getting something similar, there was
loads of old Sun
machines on ebay a few years ago. Now there are only new expensive
ones.
Although I was disappointed they stopped making desktops this might
mean the 2nd hand prices of the latest ones will drop as people go
over to Intel. Although they may go up if they are rare.
Sun discontinued the SPARC-based desktop machines for three main
reasons. First, it's very hard to make them cost-effective; they'd
have to trim their margins down to the near-nothing that the PC world
is accustomed to...which means they'd have to start making cheap
garbage. They tried that with the unbelievably crappy non-Sun-like
Ultra5 and Ultra10 machines; everyone with more than a smidgen of
real computer experience poo-pooed them loudly, and Sun listened.
(but apparently the Blade 100 [not 1000] was already in the pipeline,
too late to axe)
Second, the later UltraSPARC processors are *big*...it's not easy
to make a physically small machine with those. A proc/mem module for
a V480 is the size of a phone book and is definitely a two-hander.
These are not "desktop" processors.
Third, Sun is having great success with the Sun Ray product line.
These very effectively replace standalone desktops, and are being
deployed by the thousands. I use them myself here; they are
fantastic. There's not much point to try to make a low-cost
standalone desktop machine when they're making money (and happy
customers) with the Sun Ray line.
