  1. Re:Old gear on When Does Powering Down Servers Make Sense? · · Score: 1

    Actually as I mentioned earlier, the inrush current at power on is statistically what causes the most failures in servers. That combined with the other problem of "stiction" where hard disks that have been running for extended times are allowed to cool. Generally a percentage will either plain die, or will develop stiction whereby the heads can't develop enough inertia to move, hence the click-click sound often heard with HDD's. The idea that constant current causes damage to servers is only true if it is not limited to a value equal or below what the components are rated at. Allowing the +/- 10% fluctuations that is. Most enterprise grade servers deliberately run components like fans at higher voltages at power on to stress test during boot, this is why servers are noisy as hell for the first couple of minutes at power up and then settle down a bit. If the filtering isn't great, the inductive load, and ripple this can present to other components can often be enough to push it over the edge. Any onboard RAID controllers will also do a fair bit of interrogating of attached disks, again always not good for disks that have been running for years, and then powered off.

    I still think powering off a server is simply false economy in almost every corporate environment I can think of. Ever been in a datacentre where the UPS has failed? It's very scary! Pot luck if they all come up. The longer they've been running is directly proportional to the risk of failure.

    The analogy is actually spot on sorry! Power up and the associated current surge is when most server components fail. Your own explanation bears this out, if the light bulb was left on, it has a much reduced chance of blowing! Same with servers!

    While servers != light bulbs (servers usually aren't round), being pedantic about it doesn't contribute anything.

    I can you from my experience vMotion along with DRS and HA are absolutely awesome, no real troubles, but amazing increase of performance and availability. And at a very reasonable price I would say. But I would still baulk at the idea of powering servers off to save cents on power, as opposed to the risk they don't come online when needed. So is the solution then to have an extra powered backup for the backup, how far do you take it?

    I really think this whole argument of powering servers off is completely irrelevant and not economical (let alone common sense) except for extremely large sites that run large farms. Anything less is false economy, and the first time a site is down for a day because a server had to be rebuilt as a result of trying to save a few cents or dollars on the power bill, that will be the day management will mandate that under no circumstances are servers allowed to be powered off again except for maintenance.

    Again, it's not the cost of the power that matters in 99% of companies, it's the risk to business continuity and data that is the more important factor, and that means running servers 24/7 is cheaper insurance than the problems that could occur by saving a little on power costs.

    While it's cool technology and I absolutely love using ESX, I run several clusters, if you provide any services and provide any decent form of SLA, you actually can't afford to have the temporarily non-loaded or lightly loaded servers powered off. If another node failed during this period, the time to wake up the powered off server and then vmotion all the virtuals could be very long and likely cause problems with uptime, and thus the SLA you offer customers.

    I still think powering servers off is the wrong answer, if you can power them then essentially they aren't needed. If you can power off an ESX node that has the virtuals vmotioned off it with none off the virtuals powered down, then that server clearly isn't needed, and what probably is, is a memory upgrade on the other nodes allowing more consolidation. but by reducing the number of nodes you increase the distributed load on each other machine, and increase the risk of failure. ESX nodes can be roughly thought as similar to a RAID 5 array, but with servers instead of disks.

  5. If they can be powered off are they needed? on When Does Powering Down Servers Make Sense? · · Score: 3, Insightful

    I would think that if any servers can be regularly powered off, then they probably fall into one of two categories, they aren't really needed or they are only loaded at certain times. In both cases there's a good reason for consolidation, whether it be physical or virtual. obviously virtual gives the best bang for buck. I run several ESX clusters and despite dept's not trusting virtual servers, they all come around in the end. I think virtuals really are the only way to go to really save money, space, power, and the all important UPS load. Don't forget, the myth about hard disks dying after they have been running for a long time and then allowed to cool after a power failure, well that myth isn't a myth, it happens, and it happens a lot.

    I cannot think of situation where powering off a server that is needed provides any benefit whatsoever, you might save a few dollars, but as we all know when you're IT dept struggles to get budget for anything, the risk of failure and the HUGE costs associated with that far outweigh ANY power savings you might achieve.

    I don't give a rat's arse if powering off a few minor servers saves $100 a month, when if the disk dies after it cools down, and I then have to go into repair mode to find out what peculiar apps were installed on the server, somehow scrounge another system with no budget, and then rebuild the whole damn thing, only to find out the developers have changed so many configurations it takes weeks or months before everything is really working as it should. Even more joy is that usually occurs at night if power is lost, as we have nothing better to do anyway. NO THANKS!

    For companies who have massive budgets for IT, and routinely swap out hard disks, etc, maybe that would work, most companies I know and have worked for over the years though tend to view IT as a parasitic loss centre run by people who spend there days watching the blinkety lights and having fun, "it's just a bunch of servers, how hard could it be" or "how much money could they need, I can go the PC shop and get a whole quad core rig for $600!"

  11. Re:Are there ANY big box companies with good servi on Dell Found Guilty of Fraud, False Advertising · · Score: 1

    Funny enough while working for a fairly major tech company, I ordered a large amount of HP laptops, no special contracts or anything, but extended warranties on all. Over a 3 year period where we had the engineers previous laptops dying at the rate of around 4 or so with major failures, and a further few with more minor keyboard/screen/power supply issues every year, the HP's travelled the world and performed flawlessly, with only two service calls needed for approx 15 laptops, each had the spare part waiting within around 12 hours max.

    With tape units the support is just perfect, a month ago we had a tape unit eject mechanism stuff up, with 1 month of a 3 year warranty to go, HP had a replacement (refurbished unit) there the following morning, unfortunately, it was DOA, (faulty power connection to the switch) so I rung HP and they had a brand new unit the following morning. Every corporate dealing I have had with HP over the last 10 years has been unbelievably good. I could reel other things like laptops people had password protected the BIOS that were'nt under warranty but HP spent 45mins on the phone helping me to remove it.

    As a consumer though I must admit HP support left a lot to be desired, I recently had to go in to bat for my nephew who bought a laptop from Harvey Norman (who were the most useless and deceitful pricks possible to him and his mother). After 6 months it packed up with various faults, and then spent most of the following 6 months either in repairs, or sitting on the shelf at Harvey Norman who were lying and saying it was with the HP authorised repairer in Clayton. The repairer sent it back one last time but it packed up again with the same faults that day. I got involved as it had taken 6 weeks for the last repair and was now out of warranty, so the repairer who was supposed to have fixed it, stated it would cost around $1000 for repairs.

    To HP's credit, when I initially rung them they correctly stated it was out warranty, but luckily I had collected all the paperwork, and hassled Harvey Norman for the previous repair details, as well as looking up HP's own part and maintenance manuals, and proved it was a recurring fault that had never been fixed despite being in for repairs 6 times! When I provided them the details of the shoddy repairs, along with their own recommended repair procedure for the faults, they immediately agreed to send it to the repairer, and the motherboard as well as the screen driver would be replaced regardless of any testing. Upon pickup (3 weeks later!) I made sure I obtained copies of all the repair paperwork, and got the staff to write down exactly what work was done. I immediately opened the unit up, and what dd I find, they hadn't replaced a single part, and the unit still had the same fault!

    This then started a 2 month merry go round with HP, as I now had photo graphic proof of consumer fraud, as well as an authorised HP repairer deliberately forging repair docs, and charging HP for parts that were never fitted! In the end I had to send a fairly terse letter that if I didn't have a resolution by COB that day, I will be forwarding copies of all the photos I had taken of the parts before and after the "replacement", along with copies of the docs and parts serial numbers signed by the repairer that new parts had been fitted, to the entire Board of Directors of HP USA, as well as the local media, and a report to consumer affairs.

    Within an hour HP had gotten back to me and offered a couple of very much higher specced models to choose from, along with an extended warranty in exchange for the dead laptop!

    All in all, an absolutely horrible experience for my nephew and his mum, who saw his first laptop wasted, and then treated like crap by Harvey Norman at Southland, and then a HP repairer lying repeatedly and forging documents. Luckily the fact I work for a large corporation, and that I have enough knowledge and push allowed me to finally get satisfaction, but you just wouldn't believe how hard I had to work for it!

    I'm playing around with solar power myself on the cheap and there are a number of very worthwhile uses. For example, Ebay has a large number of sellers selling LED downlight replacements, (MR16) that draw around 100ma while producing a fairly large amount of light, although the angle is much narrower and whiter than halogen downlights. These generally are from around $5AU to $25AU depending on power rating.

    There are also a number of intelligent (micro controlled) solar chargers, a good charger is critical to getting the best possible performance out of the cells, while keeping losses to a minimum, and also charging the batteries for maximum life. These are around $80-$125AU. Cells themselves are very cheap, now, Oatley Electronics over here sells a complete 100w package among others, with a battery and rudimentary charger.

    Batteries can be obtained cheaply, I use electric wheelchair batteries rated at around 12v and 35 to 45amphour. These are designed for deep cycling and are usually replaced when the chairs are serviced, regardless of the condition. Batteries from auctions for commercial UPS'es are also great, usually 2v at around 100-200amphour! Just don't short them, can be very nasty.

    I'm slowly adding additional standard downlight fittings to all the rooms in my house, and fitting LED downlights to run off (two at the moment) solar cells hooked up to a smart charger/regulator and 12v cells. No electrician required, no heat, very minimal expense, doesn't affect existing wiring, although clearly marking the cable runs is advised for safety. Long term i'll be hooking up to the solar system a ventilation system throughout the house to help with moving stagnant air from inside wardrobes, etc to cut down on any mildew problems in winter. As well as overhead fans during summer to help with circulating air.

    All up for 2 x 12v 20watt cells, 20 odd LED downlights, a smart charger/regulator, and 3 x 12v batteries, i'm out around $450-$550AU. People might argue that if would ages to recover that cost in the electricity bill savings, but this isn't about just that, I can now also do things that I wouldn't normally do with standard electric powered stuff because the cost now is nill.
