Standards For Dedicated Server Temperature
Apr 20, 2008what are the 'standards' for server temperatures.
We are testing some new DELL servers, and we're hitting 65 - 70degrees Celcius, was wondering if anyone experiences these temperatures.

Optimal Server Room Temperature
Jul 26, 2007We have a very small server/network/telecommunications room with one server rack housing 2 racked Dell servers, 2 3com router, 1 switch, 2 UPSes and 2 tower servers.
In addition, our phone system is housed in this room.
The temperature is normally about 77 degrees Fahrenheit. It is a VERY small room and central air does not reach the room. Their is only a portable A/C(I guess its fairly powerful) that we leave on all night and day at its max. However, the temperature stays about a constant 77 degrees.
I read in some articles that the temp should be about 58 degrees Fahrenheit. Is that true?
Is our equipment being damaged by the temperature in the room?

cat /proc/acpi/thermal_zone/THRM/temperature always gives 30 C.
I recently got a Intel Quad Core with 8 GB RAM. When the load is nearing 1.00, the kernel flashes the message below. It is always CPU1 and CPU2 while CPU3 and CPU0 is reported to be normal.

Temperature Fluctuations In Datacenter
Jun 26, 2007I have been loosely monitoring the system temperature on my co-located 1U server and have noticed fluctuations of up to 9 degrees Celsius (or around 18 degrees Fahrenheit) depending on the time of day, and the current weather in the city the data center is located.
In the dead of night the system usually reads around 28C but in mid afternoon it will get up to 34 - 38C, not terribly hot, but the effect of the constantly changing temps on the hard drives has me concerned. Server load doesn't seem to be a huge contributor to the temp increase since it's peak load times are usually from late evening until early morning, so I'm guessing this is the data center heating up and cooling down following the outside weather patterns.
do any of you others see temperature swings like this on your servers and how much would be normal?

Google Doubts Hard Drives Fail Because Of Excessive Temperature, Usage
Feb 17, 2007Mountain View (CA) - As a company with one of the world's largest IT infrastructures, Google has an opportunity to do more than just search the Internet. From time to time, the company publishes the results of internal research. The most recent project one is sure to spark interest in exploring how and under what circumstances hard drives work - or not.
There is a rule of thumb for replacing hard drives, which taught customers to move data from one drive to another at least every five years. But especially the mechanical nature of hard drives makes these mass storage devices prone to error and some drives may fail and die long before that five-year-mark is reached. Traditionally, extreme environmental conditions are cited as the main reasons for hard drive failure, extreme temperatures and excessive activity being the most prominent ones.
A Google study presented at the currently held Conference on File and Storage Technologies questions these traditional failure explanations and concludes that there are many more factors impacting the life expectancy of a hard drive and that failure predictions are much more complex than previously thought. What makes this study interesting is the fact that Google's server infrastructure is estimated to exceed a number of 450,000 fairly mainstream systems that, in a large number, use consumer-grade devices with capacities ranging from 80 to 400 GB in capacity. According to the company, the project covered "more than 100,000" drives that were put into production in or after 2001. The drives ran at a platter rotation speed of 5400 and 7200 rpm, came from "many of the largest disk drive manufacturers and from at least nine different models."
Google said that it is collecting "vital information" about all of its systems every few minutes and stores the data for further analysis. For example, this information includes environmental factors (such as temperatures), activity levels and SMART parameters (Self-Monitoring Analysis and Reporting Technology) that are commonly considered to be good indicators to describe the health of disk drives.
In general, Google's hard drive population saw a failure rate that was increasing with the age of the drive. Within the group of hard drives up to one year old, 1.7% of the devices had to be replaced due to failure. The rate jumps to 8% in year 2 and 8.6% in year 3. The failure rate levels out thereafter, but Google believes that the reliability of drives older than 4 years is influenced more by "the particular models in that vintage than by disk drive aging effects."
Breaking out different levels of utilization, the Google study shows an interesting result. Only drives with an age of six months or younger show a decidedly higher probability of failure when put into a high activity environment. Once the drive survives its first months, the probability of failure due to high usage decreases in year 1, 2, 3 and 4 - and increases significantly in year 5. Google's temperature research found an equally surprising result: "Failures do not increase when the average temperature increases. In fact, there is a clear trend showing that lower temperatures are associated with higher failure rates. Only at very high temperatures is there a slight reversal of this trend," the authors of the study found.
In contrast the company discovered that certain SMART parameters apparently do have an effect drive failures. For example, drives typically scan the disk surface in the background and report errors as they discover them. Significant scan errors can hint to surface errors and Google reports that fewer than 2% of its drives show scan errors. However, drives with scan errors turned out to be ten times more likely to fail than drives without scan errors. About 70% of Google's drives with scan errors survived the first eight months after the first scan error was reported.
Similarly, reallocation counts, a number that results from the remapping of faulty sectors to a new physical sector, can have a dramatic impact on a hard drive's life: Google said that drives with one or more reallocations fail more often than those with none. The observed average impact on the average fail rate came in at a factor of 3-6, while about 85% of the drives survive past eight months after the first reallocation.
Google discovered similar effects on hard drives in other SMART categories, but them bottom line revealed that 56% of all failed drives had no count in either one of these categories - which means that more than half of all failed drives were put out of operation by factors other than scan errors, reallocation count, offline reallocation and probational counts.
In the end, Google's research does not solve the problem of predicting when hard drives are likely to fail. However, it shows that temperature and high usage alone are not responsible for failures by default. Also, the researcher pointed towards a trend they call "infant mortality phase" - a time frame early in a hard drive's life that shows increased probabilities of failure under certain circumstances. The report lacks a clear cut conclusion, but the authors indicate that there is no promising approach at this time than can predict failures of hard drives: "Powerful predictive models need to make use of signals beyond those provided by SMART."
Dedicated Virtual Server Vs Regular Dedicated

Dedicated Server Vs Virtual Dedicated Server ..
Sep 7, 2008I am currently using a shared hosting but due to increasing traffic and server load my existing host is not able to provide reliable services and I am planning to upgrade my hosting service.
While I was searching for Dedicated Servers, I learnt about Virtual Dedicated Servers but I am not very sure about their reliability? Are Virtual Dedicated Servers useful? My website current serves over 2500-3000 visitors a day resulting in 30,000 pageviews and I am expecting the traffic to grow by atleast 2 folds in the next few months as I start some PPC campaigns and Email Marketing for my website. Can a Virtual Dedicated Server cater such needs assuming my website to be more of less dynamic website written in php?
Plesk 11.x / Windows :: Don't Have Root Access To Server As It Is A Webfusion Dedicated Server
Oct 16, 2013I have Plesk 11.5 (service provider mode) on a Windows 2008 server IIS7.Most of my sites are developed in .asp and therefore i use a custom 500-100.asp error page that check s the IP of the visitor then displays either a friendly error, or if its my IP a full error of what has happened (it also emails me the error). This allows me to debug pages easily whilst developing and to keep an eye on anyone trying SQL Injection hacks on my sites (as the error and email also have session variables and IP address).I dont have root access to the server as it is a Webfusion dedicated server.I have following the Plesk documentation -
1) Switch on custom errors for the subscription
2) Look in virtual directories and navigate to error documents
3) Find the error in question (500:100) and change it to point at either a file or URL
FILE - I had the data centre add in the 500-100.asp error page in to the virtual template so that my page is available in the list of virtual files - this didn't work but that maybe because its not a static page??
URL - when i add the path it says its incorrect, if i add a fully qualified address, it accepts it but it doesn't work.give me a specific example of the URL that can be entered relative to the root as the format in the documentation isn't accepted. The last step is to restart IIS which is also an issue as i cant seem to do this from the Plesk panel..It is as if it isn't catching the 500:100 error, and only catching the general 500 error??

Dedicated Server, VM Or VPS
Oct 21, 2009I got control of some colocation resource in Taipei, Hong Kong and several cities in China (Beijing, Shanghai and probably Guangzhou & Shenzhen), and is now considering starting a business by deploying blade servers into my racks with Internet bandwidth as well as private bandwidth interconnected between the above IDC.
My target will be corporation, web developer / SI who want their / their clients' web site or IP application online with target users in those regions.
I prefer to deploy VM or VPS instead of dedicated servers as space/electricity in China is very expensive and higher density should be the way to go.
So I'd like to know more what the difference is between VM and VPS in terms of customer perception and actual features.
In areas of VM and VPS, which vendor do you recommend and why?

I wondered if anyone else had experiance using these systems and/or this host also?
And wanted to know if most thought these would be acceptable to run Shoutcast Hosting ? I know it depends on resources etc but I mean generally speaking with these specs. Im pretty convinced to get this rather than a VPS.
