Achieving maximum speed

To be able to bring out the full speed of ©XSIBackup-Datacenter, which is probably well above your most optimistic expectations, you will need a fairly capable CPU. Don't get us wrong, a simple double core Pentium will suffice, just don't try to break some speed limit with an Atom processor.

• All Pentium, i3, i5, i7 and i9 CPUs score above the minimum requirements, even pretty old ones.
• All fairly recent ©XEON CPUs, even the low end series (E), score way over the minimum requirements for maximum speed.
• In case you find yourself in a situation in which you are limited by some single core performance limitation, i.e. you are using an Atom CPU and you can't make it better, just disable --compression on your backups and eventually allow the remote FS to perform the compression on the block chunks on the other side. This technique allows to shift part of the CPU load to the remote end when transferring data over IP.
• And do not forget to enable cache on your controller should you need to: enabling cache on an HP disk controller

Note:
We have made a correction to this text, as some tests with an old Xeon CPU were throwing poor results due to the HD controller, not the CPU itself. Most XEON CPUs since more than 10 years ago will more than suffice for ©XSIBackup-Datacenter operations.

Re: Achieving maximum speed

It sounds like XSIBackup-Datacenter was made to only use a single thread on a single processor, how come? In today's server environments it's not so much about getting the highest gigahertz processors anymore, most of us running cloud services often look for higher number of cores. Does this mean that if I got a 32 core processor only running 1.2ghz each that XSIBackup-Datacenter will not perform well?

Re: Achieving maximum speed

XSIBackup-Datacenter is a silent backup service in the background, it does not want all cores in your server, it does not need them, it must not use them. Your processing power must remain available for your services, not for some service that is overutilizing CPU in your server when it doesn't need it.

XSIBackup-Datacenter does not need more than a pentium single core to achieve maximum speed. You should only bee concerned about your CPU if you are, per instance, using some Atom CPU or some ancient XEON.

It's not all about frequency, it's the CPU architecture that determines how fast a single core will perform, one single core in your server should be enough to reach XSIBackup-Datacenter full potential.

If you find it's not achieving as it should publish here, anyway, first of all make sure that you have activated caché in your controller's BIOS, its such a common issue. HP controllers come with the cache off by default.
