On what necessarily to pay attention at the lease of server? What factors at the lease of server do have a qualificatory value, and what it is possible to ignore? Specify possibility of receipt of discounts on a server, even if these discounts are not pronounced officially.
If a project implies the lease of server on the protracted term, then it is advantageous to pay a lease for example on half-year, and discount about 10-15% at the lease of server on such term practically every provider is able to give.
Specify actual speed of network connection that is distinguished by a provider on a server. That a server is connected to Shared 100 Mbps to port, quite not means that you will be able to count on such speed. Probably, it will be given you stably 10-25 Mbps, with possibility of the use of port on 100% in lances.It is also important to know whether there is dividing of traffic by the incoming/outgoing, internal/foreign et cetera. Find out, what monthly volume of traffic you can expect on, and what terms his overrun is paid on. Obviously these limitations are specified far not always.
Specify, whether you deal with a new machine, or a server was before used. It is critically important, that on a server new hard disks were set! It is the most vulnerable element of the system, and if disks have normal test indexes even, but are not new - the risk of damage or loss of data increases because of their wear.
It is also necessary to specify, on what terms replacement of knots of server is produced on their leaving from a line-up. It must be produced free of charge and only due to a provider.
Whether your provider can to offer to you access to the management by a server through KVM (remote access to the server at vehicle level is possibility to set OS from a disk, to produce tuning of BIOS et cetera), and access to the remote management by a feed and restart of server.
It is very comfortable options, that, actually, reduce a necessity for product support services from the side of provider to the minimum. In addition, necessarily thoughtful about organization of backups, that will be placed on other server. Do not forget that safety of your data - it your personal responsibility only.
