[QUOTE=leach139;34807128]Serial console? (wild guess, just going on the fact that 38400 is a baud rate)[/QUOTE] I set up a null modem cable between two computers. Popped open minicom on one, HyperTerminal on the other, and eventually got it working as a basic, primitive chat system. Hardly the most exciting thing, I know, but it was interesting to get such old technology working. And I do mean primitive: this is 70's-era technology. 38400 bits per second, 8 bits data/no parity/1 stop bit. That comes out to about 4 KB/s. Now granted, it was completely pointless. I mean, if I wanted data transferred, I grab an Ethernet crossover cable and hope Fedora comes with the proper drivers for the gigabit ethernet card. It was mostly to fuck around with ancient technology. [editline]21st February 2012[/editline] [QUOTE=Brt5470;34807137]Guys, what are Sun servers good for?

[editline]21st February 2012[/editline] [QUOTE=inconspicious;34807243]You could host a decent database/webserver with them I suppose, depending on your internet connection.[/QUOTE] What is the fun in databases.
[QUOTE=Brt5470;34807395]So they can't do any decent rendering or anything?[/QUOTE] It really depends on what they are. If they're just NAS units (what I showed), they're only good for storing data. Admittedly, they'll scale into the petabyte range, but they can't do anything with the data. If they're actual servers, they might have some better use. At the very least, they'd be able to run (certain) game servers well. Or make for really good web servers (or other "boring" stuff). If Minecraft didn't have x86 dependencies, I'd say that - you could easily run multiple servers on a single T4 processor. Rendering though... probably not, especially if they're old ones.
My boss emailed me saying they are sunfire 440's Edit: Looks like they aren't anything interesting, atleast not now. My desktop is faster. [editline]21st February 2012[/editline] Can someone explain the draw of 2.5" SAS drives? These bitches are like 150GB and cost something like 900 dollars and we're constantly replacing them in our data center.
My 24-pin and CPU power 8-pin Bitfenix cables are coming in on Thursday. Cool.

These bitches are like 150GB and cost something like 900 dollars and we're constantly replacing them in our data center.[/QUOTE] Drives identified by WWN, not port, pop out drive, pop in somewhere else, still same identifier, server goes down, migrate discs to another server in no time. Multipath I/O (fault-tolerance) Error-recovery uses SCSI stuff instead of ATA SMART, more functionality. Not to mention the whole SAS domain stuff.
Also, aren't they usually 10K or 15K RPM drives instead of 7200? (Also also, if you don't want the Sun Fire V440, I'll take one)

I thoroughly enjoy the W8 bootloader. I got rid of my linux partitions because the battery life with them is terrible.

These bitches are like 150GB and cost something like 900 dollars and we're constantly replacing them in our data center.[/QUOTE] Yum. Enterprise grade 2.5" drives are epic. Smaller platter = faster access times, problem is largest capacity you can get is 1TB in 2.5" 7,200RPM sata or SAS. I believe you can get 900GB in 2.5" 10K, which are around 400-600 a pop. I believe you can also get 300GB in 2.5" 15K. But honestly, if you care about random access, 10K 2.5" 900GB will be more than fast enough, and gives you a decent performance/GB. Some new 3.5" drives are now also using 2.5" platters, but in a 3.5" drive format. Like you know, the velociraptors, they use a 2.5" drive, but are loaded in a 3.5" heatsink. Also Server manufactors like Dell, HP, IBM etc usually uses drives from the likes of Seagate or Hitachi for enterprise. The reason they are alot more expensive than the usual OEMS, are because of custom firmware, and HP uses Dual port SAS for higher I/O throughput. SAS also has better ECC, and various RAS features.
Yet another feature in Chrome that exists, and I had no idea it did. Watching some Top Gear, need to convert mph into kmh. [img]http://i.imgur.com/JJ7aQ.png[/img] Oh. (mph into kmh is the same conversion as miles into kilometers since you can eliminate h from the equation)
I love that feature. Unit conversions were never my strong suit.
This is what I love. After fighting with apache and SNMP, you get observium working, shits leet: Even supports IPMI :D [IMG]http://i.imgur.com/HoZF7.png[/IMG]
So you work for WebNX.
[QUOTE=MC3craze;34809043]So you work for WebNX.[/QUOTE] that was so easy to see through
[QUOTE=MC3craze;34809043]So you work for WebNX.[/QUOTE] No I don't. I work for a private company, but given the fact that I compete with some known people on here, I want to stay private. Wingless knows what I do though :). Some of my servers are in WebNX, they are rentals yes, I got such a great deal it was hard to pass on. Once SB-E releases, we'll be building servers on that platform forsure.

For my own in-house built machines, they will be running custom compiled kernals for sure :) [editline]21st February 2012[/editline] [QUOTE=Killowatt;34809137]My heart just dropped.
