Official Blog - Contabo. Today, we have got some great news for you: The experts at Hosting. Advice have carefully examined us and our services and published a detailed review about us. Besides our products, namely the webspace plans as well as our VPS and dedicated servers, they also checked and compared our overall features, our prices and the usability. All in all, we are delighted about a rating of 4. You can read the full article by clicking the following link: Review of Contabo's services. From now on and by your request, we offer you an internet connection of 1. Gbit/s (for every server) for our dedicated servers Dual Xeon and 1. Core. With this upgrade, your server will receive an Internet uplink of 1. Gbit/s (=1. 0. 0. Mbit/s) instead of the regular port. We use a high- quality network card from Intel in order to provide you with that bandwidth. Centos 6 Create Software Raid 1e PerformanceThis upgrade is especially suited for customers who generate traffic peaks, which exceed the standard connection of 1 Gbit/s. You can add the 1. Gibt/s- port for 9. New customers can select the upgrade during the order process of the respective dedicated server on Contabo. Do you already have a dedicated server and would like to add this upgrade? No problem at Contabo! Existing customers can order this upgrade at any time. Please contact our customer support department and specify your wish. To compare the software in this project to the software available in other distributions, please see our Compare Packages page. Notes: In case where multiple versions. This year, as we have proudly informed you earlier, we won the German Data Center Award for our data center in Nuremberg. An independent jury awarded us first place in category 6: "Increase in energy efficiency through reconstruction in an existing data center" Today, we show you some impressions from our cooling systems. Day and night, they ensure that thousands of servers receive reliable air- conditioning in our data center in Nuremberg. These pictures show you our redundant air- conditioning systems. They are highly efficient and state- of- the- art machines and use external air for cooling - leading to significant savings in energy consumption. There you can see our double- pumping plant. It transports the cooling water into the data center. Should it ever fail, the second one will take over instantly and ensure that your servers will always receive the best cooling. ![]() By the way, our website provides more information about our data centers. It does not matter if you do website hosting, provide a gameserver or use other services, if you have no space left on your HDD/SSD problems will occur. Your websites might not be reachable anymore, your players cannot connect to your gameserver or all other services will not start. To avoid this it is necessary to find big files on your system and to get rid of them. Today we will show you how to do this. Linux: 1. Connect to your server using SSH2. Execute the following code: # Change into root folder. Find the top 1. 0 files. This may take a while. Sh {} + | sort - rh | head - n 1. ![]() Once finished, a list of the ten largest files will be displayed. Normally these files might be old downloads or big log files. Files that are no longer used can be deleted, of course. Before deleting log files you should check them for errors you can solve so that the issue will be permanently fixed.

Please make sure not to delete Windows system files ? . With this tutorial we will explain certain types of RAID levels to you. Some of you might have already experienced a loss of data, no matter if it was an SD card holding some vacation photos or a hard disk holding important files. Losing data can be very costly if you try to restore them by some specialist. An expert is needed and the procedure takes a lot of time, the easiest way to avoid those costs is simply to avoid any data loss in the first place. This overview is not relevant for any VPS, your VPS systems are already running safe on a RAID system monitored by experienced technicians. Creating backups is still very important, a RAID does not replace any backup! You can find further instructions within the following tutorial: Data loss and how to avoid it. There are some points which you should think about first, there are several results depending on your requirements. How important is the performance? How much data security should be provided by the RAID? Are system resources available to manage the RAID, such as CPU and RAMDepending on the results of the above questions and your budget, there are several options available: A hardware RAID is always more expensive but provides the best performance and security (if combined with a battery backup unit). A software RAID is the easiest way to go for a RAID, it is able to handle almost any type of RAID and can be set up within a few minutes. An overview of available RAID levels is shown below: RAID 0. The RAID 0 provides increased write and read performance, the data will be distributed to at least two disks. Since there is no redundancy all data will be lost in case one disk fails. At least two hard disks are needed. No disk redundancy at all. Maximum (complete) storage capacity available. Improved read and write performance. RAID 1. The RAID 1 provides increased read performance (depending on the software/hardware controller used), all data will be mirrored to a second disk. There is also a RAID 1. E available - in that case all data will be mirrored to additional disks too. At least two hard disks are neededn- 1 disks can fail. Improved read performance. RAID 5. The RAID 5 provides increased write and read performance, the data is written to at least two disks, an additional disk is always used for storing parity data. The parity data has to be calculated for every write - so for very write intensive applications the RAID 5 requires a lot of performance due to the necessary calculations. At least three hard disks are needed. One disk can failn- 1/n of storage available (n = number of disks, with three disks = > 2/3 of total storage)Improved read and write performance. Requires a lot of CPU time. RAID 6. The RAID 6 provides increased read performance, the data is written to at least two disks, two additional disks are always used for storing parity data. The parity data has to be calculated for every write - so for very write intensive applications the RAID 6 requires a lot of performance due to the necessary calculations. As there are two parity bits saved on the disks, the needed CPU time is very high. At least four hard disks are needed. Two disks can fail simultaneouslyn- 2/n of storage available (n = number of disks, with two disks = > 2/4 (half) of total storage)Improved read performance. Requires the most CPU time. RAID 0. 1A RAID 0. Each volume group is configured to have a RAID 0, those volume groups are mirrored in a RAID 1. With a total number of four disks one entire volume group can fail with both disks and no data will be lost. At least four hard disks are needed. Two disks can fail simultaneously if they belong to the same logical volume group. Half of total storage capacity is available. Improved read and write performance. RAID 1. 0A RAID 1. Each volume group is configured to have a RAID 1, those volume groups are striped in a RAID 0. With a total number of four disks, two disks can fail simultaneously and no data will be lost - the failed disks must not belong to the same volume group. At least four hard disks are needed. Two disks can fail simultaneously if they do not belong to the same logical volume group. Half of total storage capacity is available. Improved read and write performance. The difference between RAID 0. RAID 1. 0 is only visible with six or more disks, if you have six disks a RAID 1. We do recommend using a RAID 1. RAID 0. 1 even if you do only have four disks. Some RAID controllers do not even support a RAID 0. RAID 5 and RAID 6 require the highest CPU time since a checksum has to be calculated on every writing process to the disk. Only a few enterprise RAID controllers do support RAID 5 and RAID 6, due to the need of calculating checksums the writing speed might suffer which might then cause problems when using write intensive applications. For our dedicated servers it is always possible to order additional hard disks or RAID controllers, current prices can be found on our web site.
