Comment Re:Screwed? (Score 1) 586

I mean, it's great to have someone available to handle that sort of thing, but can you really sustain a job with this as your only skill?

I personally know a guy that owns a web design service & consultancy with $100k/yr in revenue. Of course, he does much more than simple HTML pages. I know he has done things in ASP and PHP, maybe some other tech as well.

Comment Hypervisors, etc... (Score 1) 1

I have a couple of old dual Xeon systems (32 bit/no hardware virtualization) that did well running VMware ESXi Server. I easily ran 4 VMs on those older CPUs without them breaking too much of a sweat. However, I quickly found that the bottleneck was hard disk performance. (A pair of Ultra160 SCSI 10kRPM drives...).

Disk I/O is still the bottleneck for me. These days I've got a dual quad-core Xeon 64-bit system w/ 16GB RAM & 4x500GB SATA HDDs attached to the onboard SAS controller. As far as CPU & RAM are concerned I can pretty much do *anything* I want, but I find that disk I/O is the limiting factor. More than 2 VMs per spindle (or RAID volume) and you'd better not have disk intensive apps on those VMs sharing that spindle. I am sure that if I had 10kRPM Raptors instead of 7200RPM drives it would do better (and 15kRPM SAS drives even nicer) but in the case of Raptors or SAS drives I really can't justify the cost for a "test environment". Which is what the machine really is - a place for me to test out scenarios before putting them into practice.

The more spindles you have to spread your VMs across, the better, and if I'd had more drives in those older Xeon systems I would have spent a lot less time waiting on disk operations to complete! Instead of buying four 500GB drives, I should have bought eight 250GB drives (onboard SAS is 8-port! :D). Oh well...

Comment PCI-X SAS Controller (Score 1) 2

If you do want to go with a SAS controller on your PCI-X bus, I would like to say that I've had good luck with an LSI 3080X-R PCI-X SAS RAID controller. Linux has good drivers for it. I actually bought it to work with VMware ESXi as ESXi is very particular about it's storage hardware. That LSI card goes for about $180 US on eBay (approx $133 Euros). If you were to buy it at full pop on Amazon or elsewhere it comes to about $291 US (approx $215 EU). I can only find one decent auction on ebay at this time for that card. Here's the link. eBay is where I got mine from, new in box, for $170 US (auctioned on eBay by Buy.com actually).

Let me know when a mobile phone can serve as a CAD workstation, video editing workstation, or other high performance need. We have plenty of those around here where I work. Also need to mention dual wide screen monitors in imaging departments like radiology (they rotate them vertically for x-rays, etc.) It's more likely that thin clients will become the norm again before mobile devices replace desktops. We have a lot of Citrix thin clients here and that number is growing steadily...
