This upgrade will add an Intel SSD to your server. SSDs represent a storage technology which - compared to usual mechanical hard disks - offers extremely improved read/write performance as well as higher transfer rates. For applications such as databases, SSDs can create massive performance gains as compared to standard HDDs.
If you choose a SSD upgrade, we will install the operating system on the SSD since this maximizes the performance boost. If you do not want the OS installed on the SSD, please use the field for special requests during the order process to tell us where the OS should be installed.

A Samsung 830/840 Pro or a Crucial M550/MX200 SSD will be built into your server.
Samsung and Crucial SSDs represent the performance pinnacle of the SSD market.

The SSD is connected via S-ATA 6 Gbit/s, of course, if the mainboard allows it (all X and Dual Xeon servers support S-ATA 6 Gbit/s).

With this upgrade, your server will be equipped with an Intel 750 Series SSD with 400 GB of space. The Intel 750 Series makes use of the new NVM Express technology and is not connected via a S-ATA cable but via PCIe. Regular SSDs already outperform HDDs massively. The Intel 750 Series ups the ante even more and achieves benchmark results two to five times as high as a standard SSD. If you want the maximum I/O possible for your server, there is only one choice: The Intel 750 Series SSD.
Due to its unique NVM Express interface, the Intel 750 Series SSD cannot be used as the first boot device or OS device.

With this upgrade your server will receive four 1000 GB HDDs which will be connected to a high quality hardware RAID controller, configured as a RAID 10 array. These are 24/7-HDDs which fit perfectly for this type of usage.

Choose this upgrade to equip your RAID controller with a BBU. This will enable you to activate the write cache of the RAID controller. The write cache drastically improves the I/O rates of the RAID array and is recommended for high performance applications.
Furthermore, this upgrade gives you the choice whether you want a RAID 10, 5 or 6 with your controller. If you would like us to configure your server with a RAID 5 or 6, please send us a short e-mail after you have placed your order so that we know about your choice. Otherwise, we will configure a RAID 10.
Please select this upgrade only in conjunction with one of the RAID 10 upgrades.

With this upgrade, your server will receive a 1 Gbit/s uplink (=1000 Mbit/s) instead of the regular 100 Mbit/s port. Set new standards regarding the transfer speed of your server and choose the 1 Gbit/s port! Your server will still have unlimited traffic, of course!

By choosing this upgrade your server is being connected to a 1 Gbit/s (=1000 Mbit/s) dedicated switchport (non-shared) and 500 Mbit/s of bandwidth are reserved only for you. You are able to use the full 500 Mbit/s with both your upstream and your downstream - 24/7 without limitations, no port capping, etc. We do guarantee this bandwidth allocation to you exclusively, thus, you don't share this bandwidth with any other server. Even if you should use the whole bandwidth all the time, we will not throttle your serverport!
If you decide to order the "500 Mbit/s dedicated bandwidth - 24/7 guaranteed" upgrade, you do not have to order the "1 Gbit/s port" upgrade. The price of 149.99 EUR already includes this.

With this upgrade, your server's disk space will be set up as software RAID 1. RAID 1 stands for the concept of "mirroring", which means that all data is stored on a second hard disk exactly like on the first . The advantage of RAID 1 is that data can be read faster and that, in case one hard disk fails, the system keeps working without loss of any data.

For RAID 1, one needs two identical hard disks. If you are ordering a server which has only one HD or two HDs which do not share the same capacity, you will need to order an additional HD with the same size as an upgrade. If you, for example, order a server with one 250 GB HD and would like to use this server with RAID 1, you will also need to order the upgrade for one additional 250 GB HD.

With this upgrade, your server's disk space will be set up as hardware RAID 1. We only use high quality controllers from 3Ware or Adaptec. Hardware RAID has an even greater stability and performance than software RAID.
