  1. Buy Cheap Racks But Get Rack-Mountable Servers on Racks vs Custom Mounting/Shelving Solutions? · · Score: 2

    Lots of folks feel a need to spend hoards (think: $1,500) on enclosed racks with fans and fancy power taps and the like. Yes, they are nice but I don't think they are worth the extra cash.

    What you need is a simple tapped, extruded aluminum rack. A 19"x84" rack runs $140-$200 at DataComm Warehouse. A 21" rack runs a bit more.

    These aluminum racks don't have fans or electrical connections. Get a few tie-wraps and attach a power strip to the back and you will be living large. Since the rack is not enclosed, there is no need for additional fans.

    Spend some money on rack-mount cases for your servers. I can't tell you how much easier this will make your life and how much more professional your data center will look. A rack mount case may add a couple hundred dollars to an order. It is worth it.

    If your boss needs a justification to spend the extra money, ask him how much your office costs per square foot. With a rack, you should be able to stuff six to a dozen servers where one server once sat on the ground. Do the math for him. That alone should show him that building up is the way to go.

  2. Use ADSM for Best of Disk and Tape on Backups-Cheap IDE Drives as Alternative to Tapes? · · Score: 1

    IBM (now Tivoli) has a wonderful product called ADSM (now TSM). It backs up data from the client to a disk storage pool. It then migrates that information from disk to tape while, optionally, leaving a copy on disk.

    This gives you the advantages of doing fast backups and restores (from disk) while giving you the off site options of tape.

    It ain't cheaper than just writing it to disk, of course, but if the data is worth backing up, it's worth keeping safe, right?

    My gut reaction is that this is simply a hoax or urban legend. Unless someone can supply a first-person account, I'm going to write it off and think less of Slashdot for posting hearsay.

    There may be a kernel of truth in the story but I bet it is along the lines of someone having to pay per byte.

    See if this doesn't ring more true. A user has an offensive web site up. Someone or a group of someones DoSes the site. A person who is used to paying $19.95 a month suddenly finds himself hitting the bandwidth clause in his boilerplate user agreement. Something along the lines of 'base rate covers up to 750 mb of data transfer a month; all usage above that will be rated at $25 a gig'.

    The user gets his bill for $700 and says that he won't pay it because the hits and transfers came in the form of a DoS over the course of 30 hours. ISP says 'tough, pay the bill or be cut off'.

    Web site owner (possibly a script kiddy himself) gets on IRC/Slashdot/etc. and tells this half truth that his ISP killed his account because of a DoS. Internet becomes enraged. Etc.

    Sound more likely?

    Of course, this really could have happened just like the submission says. But I doubt it.

    I ran into a situation where a company I was working with spent God knows how much on a huge rack-mount UPS that would keep their dozen or so servers and network hardware up for three hours in case of a power outtage.

    Good planning on their part, right?

    Unfortunately, the first time they had an outtage (July in Florida), the air conditioning to this 14 foot by 18 foot room died. When I opened the door an hour and a half into the outtage, I as hit with a blast of hot air like you wouldn't believe.

    The room temperature hit 117F degrees. The internal temperature on some of the machines was certainly over 125F.

    They burned out a Cisco 5500, two CPUs and 11 10k RPM drives. I'm surprised they didn't lose more. I know and hour and a half in there would have caused me to cease funtioning.

    The irony is that the UPS was probably cranking out more heat than anything else in the room.

  7. Re: network failure should be handled by network on Linux Failover? · · Score: 1

    Slashdot has been saturated with 'IANAL' for several weeks now. I think we need a new acronym for this discussion: IDKCAHA. 'I Don't Know Crap About High Availability.'

    I've been trained in IBM's high availability product, HACMP, 'High Availability Cluster MultiProcessing' and manage a few production clusters.

    This is typical of what I'm hearing on Slashdot today...

    If a network node goes down, it's better if network equipment handles the failover.

    It ain't that simple. The node that went down has resources other than network ports. What about the application? What about the filesystems? What if the network connection is up but the application or filesystem is down? Show me a chunk of networking equipment that can handle those failures and I'll send you a dollar.

    In our production environment, we have an Oracle database running in an IBM HACMP cluster. The SSA (think: SCSI over token ring) drives are shared between the primary node and the backup node but can only be active on one node at a time.

    Should a network card fail, in the primary node, it will down the sick interface and bring up the IP and MAC on the backup card. Linux, too, can do that rather easily.

    But what if the problem isn't the network. What if the applicaiton on the primary node has failed? HACMP can down the primary node and bring the application up on the backup node, taking the disk drives with it. I have yet to find a Linux tool that will do disk failover.

    I've also seen comments in this discussion to the effect that secondary heartbeat paths are 'silly'. Obviously, the person who made that comment is insane. (We use a target mode SCSI over SSA for a heatbeat.)

    If your only heartbeat is running over the network and the network fails, neither node knows if the other is up and both nodes will attempt to claim the disk resources, come up on the same IP/MAC address and start the applicaiton. This is Very Bad. What do you think will happen when the network comes back online? I'll give you a hint. All of a sudden you've got duplicate nodes on the network. That's never good.

    To answer the consultant question, I think the person is stearing you in the wrong direction. Either you need to rethink your failover solution or you need to move to a platform that better supports the type of failover you want to do such as AIX or Solaris.

    Real Soon Now, I expect that there will a viable Linux HA solution. However, there ain't one now and that's where you are. Since you're a B2B startup with venture funds to burn, I suggest you throw some of that money toward IBM's HACMP or another commercial solution on a platform that has had an HA solution for more than a few months. I'd hate for your company to save a few bucks by using Linux and lose lots of money to downtime.

    It's been said for the last 3 years that digital cameras are replacing "film" cameras. I don't think that's happening.

    Think again.

    I work for a large newspaper (which won a Pulitzer this year, by the way). Five years ago, digital was a joke. We wanted to move that direction (digital allows us to extend deadlines) but the quality and ease of use was simply not there.

    This year, we've replaced our analog cameras in almost a dozen bureaus with digital cameras. No longer are there dark rooms in the field offices. We'd like to get rid of the analog cameras in the main office as well and, in fact, are moving that direction. As often as possible, we're shooting assignments digitally.

    Costs are down. Deadlines have been extended. Photographers no longer have to leave a sporting event at 10pm to get back to the office and have the film processed by 11:30 pm. Now the photographer waits till 11 pm to stop shooting and them simply emails the photo to the main office.

    Real estate agents who used to shoot analog film are shooting digital almost exclusively.

    In high school and college, I did a lot of shooting myself. Since I got my Nikon CoolPix 950, I haven't shot an analog picture. While I certainly see analog film sticking around for the foreseeable future (my recent wedding was shot on silver (yes, B&W)), publication work will be almost entirely digital in two years. Futher, I predict, more than half the snapshots in the next ten years will be digital.

    Which brings me to the only on-topic part of this message... Get the Nikon CoolPix 950 (or whatever might have replaced it since I bought it). The picture quality is great. The camera is ultra-flexiable. It can go fully-manual or be used as a point and shoot. I own own. My father who was a professional photographer for 35 years got one. I've talk two friends into them. I can't speak highly enough about the camera. (And I don't even have Nikon stock.)

    The only parts of the S80 that are not redundant are the processors and memory. Since both are non-moving, non-mechanical parts, they have an ultra long MTBF.

    To dispell such nonesense, ask such whiners their phone number. Then ask them what their phone number was at their last three places of residence. Ask them what their best friend's phone number is. Or their 12-digit bank account number. Of their third-grade teacher's name. Or Ken Griffy's batting average.

    Folks are certainly able to memorize random bits of information. Anyone who can't memorize seven to ten characters for a period of six months will be fired. Period. Memorizing a password is part of our job requirements.

    It used to be common for the computer room to get frantic calls from sports reporters who had locked themselves out on deadline.
