9/17    How difficult is it to host a virtualized FreeBSD server?  Not
        commercially, just want to let a friend go nuts with it.  Something
        like what's described at http://www.johncompanies.com/jc_bsd.html
        but I don't care so much about uptime and reliability.  Is this guy
        just using a jail, or is it more vmWare-like solution?
        \_ Jail.  Very straight-forward.  I love the part about their special
           technology.  You just need a unique IP/server.  -John

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

12/3    Are any of you CSUA alums working at Intel?  Is it possible that we
        might be able to hit Intel up for donated/partially donated (reduced
        price) Core i7 Xeons when they come out?  Who would be a good person
        to contact about something like that?  We're of course willing to put
        out for them - perhaps we'll tattoo an Intel logo on toulouse if that's
        what they want :-p  -- steven

7/9     Are 64-bit Linux servers popular compared to 32-bit ones?  My company
        has a server product that supports 32-bit, and we're trying to see if
        it's worth supporting 64-bit as well.  Thanks.
        \_ in my company, everything linux is 64bit except the handful of
           redhat satellite servers, because redhat's sat server product
           doesn't support running on 64bit systems (yet).  DOH!

        is starting to donate all of his money to charity. He's boycotting
        Google, Yahoo, and other mega companies because they're too big and
        too power and thinks they're all becoming the old Microsoft, whereas

        seems like I get these every 6 months or so from HP.  Do all drives
         have these kind of issues and I only see the ones from HP because
         they are diligent about reporting/fixing these issues?  Or do they
         suck?   (It's not actually their drives so...)  Also, do I really
         need to bring down my production infrastructure and fix all this

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman

8/20    When I use rsync to backup, it's pretty cool except in cases where
        I rename a directory name from the source. Rsync will just do
        a plain copy. Is there a program that'll detect renaming of
        directories (by checking for children files), or at least
        move them to a dated directory?
        \_ Not related but beware of using rsync as a backup tool.

DEDICATED SERVER "I got mine yesterday, and so far it's the most amazing thing I've yet seen. More importantly, I feel this will help bring a whole new level of stability for my customers. "Overall I'd give them an A+ for tech support and A+ for the overall system - if you know UNIX, want a dedicated host but don't want to pay over the odds, and get possibly the best hosting tech support I've ever had ... "In just a few days I installed my custom build of apache and php along with tomcat, and installed postgres as a back end. Then I added user accounts and replaced sendmail with postfix. "This morning I got a surprise in my Inbox with an email asking if things were ok. No reason for it to be asked but a company actually checking that the customer was happy? "Sunday evening (we're talking after midnight here Eastern Time) ... dropped tech support an email, expecting to hear from them Monday morning. " "I just wanted to tell you that your service is absolutely fabulous! after less than 48 hours of using your service, I have decided to become a life-long customer. order > The Network Your server will be housed in a secure datacenter. This datacenter is triple-homed (has three distinct physical connections to each of Sprint, UUnet, and Genuity) and has industrial grade uninterruptible power supplies backed by Diesel power plants, which can be used in the event of a prolonged power outage. A non-liquid fire suppression system is in place, and human personnel are on-site 24 hours per day monitoring network conditions. Your server sits behind a firewall and intrusion detection system. You may submit to us as many ipfw rules pertaining to your IP as you like, and they will be added to the firewall. In essence, it is like administering your own firewall in addition to your server. order > Unlimited Technical Support We provide extremely technical support. It is not uncommon for our support technicians to help customers chroot a name server, compile a third party mail server, or troubleshoot compilation problems. Your technical support will NOT consist of vague suggestions coming from barely technical phone reps reading from a hint card - it will come from expert UNIX administrators that have been running their own servers for years. Not only can they help you with ongoing issues, such as rebooting or examining the state of your server, but they can also help you with initial configuration issues, such as choosing which packages to install and in what manner. In addition to these technicians, data center staff monitor the physical aspect of the network 24 hours per day, ensuring climate and power remain within tolerances. order > Hardware Our steep discounts are made possible by technology that allows us to segment Enterprise class servers into multiple, independent servers - each one a completely autonomous system. Each server has multiple processors, and many gigabytes of RAM. The servers have multiple hot-swap power supplies, large hot swap fans, and all disk devices are RAID storage. This is much more reliable than a 1U server with tiny fans, non fault-tolerant disk I/O, and a single power supply. How is having your own collocated server different than simple web-hosting ? You have super-user (root) access, and have complete control over all packages, processes, and services that you wish to add. You have an IP address of your own, and may use it in any way you see fit. You may add additional users and give accounts on your system to other people. You can host any number of different web sites on your server for you or your own customers. order > Performance Each machine has multiple processors and many gigabytes of RAM - at any given moment you will have access to a large majority of these resources. This is because usage is highly non-parallel, and because server instances can be transparently moved from one physical server to the next All storage is hardware RAID for performance and fault tolerance. Directories you specify will automatically be backed up on a nightly basis. We have in place sophisticated methods of performance "smoothing" between our host machines that allows us to transparently place each server instance in an optimal performance environment. Translation: your server will never be slow due to the operations of other server nodes in the cluster. order > Unique Benefits Servers collocated in this fashion have unique benefits over traditional colocation. You are not responsible for the underlying hardware, and thus do not need to respond to equipment failures. If you crash or incapacitate your server, you do not need to wait for POST operations and other boot time delays. Further, your filesystem is not in jeopardy due to crashes or halts - there is no need to fsck or otherwise maintain the filesystem after a crash. The hardware your server exists on is much more fault-tolerant than a machine you would collocate on from a traditional provider. It is common for our servers to have three or more independent power supplies each attached to a different physical circuit, four or more independent and hot-swappable fan units, and RAID storage running on duplexed adaptors. Each of our systems can withstand a large number of component failures without interrupting service. There is a performance benefit as well - no matter how fast the single processor non-RAID systems offered by other vendors are, they do not offer anywhere near the performance of quad-processer servers running with fast RAID arrays. Sizing and performance tuning manuals conclude that performance issues are almost always due to disk I/O. The disk I/O on our systems blows away that of rackmount co-lo servers offered by other vendors. In the event of some catastrophic data loss, we can simply restore the previous nights image of your server, and restart it - a process that can take as little as ten minutes to complete. This means you do not even need to do your own backups (you may wish to backup your data more often, or to a seperate site - if so, let us know and we can help). Note that we back up only the list of directories that you specify - you will receive details in your welcome email. order > Your Environment Your server contains a fully populated FreeBSD filesystem, and is configured with a bare framework of tools (sshd, sendmail, cron, syslog, and a full ports tree). We can support you and provide documentation and HOWTOs for installing and configuring any services you would like to run, such as web servers, databases, dns servers, etc. The choice of which packages to install and how to run them, however, is up to you. You should have a working knowledge of compiling software, adding packages, changing passwords, adding users, and starting/stopping services.
