Z While both the Z and Z support dual processors, we recommend the Z if you require dual processors immediately, and the Z if you want one processor now with the potential to add a second matching processor at a later date. However if you plan on running dual high-end graphics cards, then the Z will be required since it has a higher wattage power supply.
ZWorkstations Inc. Never used. Ships in original manufacturer packaging. Refurbished: Pulled from corporate environment in working condition. Because the CPU can typically process data faster than the storage media it's pulling from, performance suffers. In a dual-core processor, the data is pulled by each processor when needed. A dual-core processor The data streams are processed at the same time, and once the data is calculated, the processors mesh the data back into a single usable stream.
This isn't to be confused with a multi-processor system, in which all processors reside on the same chip.
The multi-processor system, because of the way the data is split and reintegrated, can be significantly faster than a dual-core setup. Dual core processors are limited, however, in that they are software dependent. The software for each program must be able to organize the data sent to both processing cores, otherwise the dual-cores won't recognize the data properly, and only one processing core is used.
Cost-effective single processor servers can provide machines powerful enough for a development and test environment for your team of programmers. In this segment, you can also expect to set up your own DNS server. Most modern entry-level servers support error-correcting code ECC memory. It corrects emerging data corruption, prevents potential system crashes and helps to keep the system running around the clock. The single processor server lineup in the middle segment is also diverse.
Additionally, mid-range machines are a good fit for a moderate volume webshop or smaller online games server. Organizations can also deploy these machines as collaboration servers for fluent data exchange between different sectors. Since data may change at the same time in different locations, collaboration servers keep track of the changes and deal with proper synchronization.
There are many different applications for collaborative servers ranging from interactive 3D experiences to project management tools. If the budget allows for a top-spec single processor server, you can create a high core-count machine for more intensive workloads. Some of those applications include certain scientific simulations and statistical computations. Other than that, large volume websites and online stores can effectively run on these robust servers.
You can also create a smaller virtual environment and make a multi-purpose server using one unit. High-end servers are also suitable for potential scaling and high-speed server clusters for intensive workloads. The most apparent distinction between single and dual processor servers is that the motherboard has two CPU sockets instead of one. This is followed by additional benefits such as the massive amount of PCI lanes, two separate sets of cache memory and two sets of RAM slots.
This rarely happens since dual processor servers always have both slots occupied. One thing to bear in mind about dual processor servers is the presence of a necessary latency in such systems. This refers to the compute tasks that require the same data sets. To efficiently share the available resources and avoid interrupting each other, there is a need for NUMA non-uniform memory access. This helps with assigning available memory and devices to each CPU making the latency times as low as possible.
But, in the workloads intended for these servers, this is not an issue. Dual processor servers and multiprocessor systems, in general, are the best options for space-restricted environments. When a business requires as much compute power as possible in a single unit, they need to use multi-socket setups to fit a large number of servers in a constricted space.
Quite often dual processor servers contain those top of the line processor chips. This makes them suitable for virtually every market segment and business use case. Note that typical small business applications will not benefit from the high core-count.
Where these servers really shine is in multi-threaded CPU intensive applications such as scientific high precision computations and simulations. The same goes for machine and deep learning , render farms and similar HPC deployments where an extreme amount of CPU calculation takes place. Environments using a large database tasked with numerous simultaneous queries take advantage of servers powered by two CPUs and as many cores as possible. The more cores are available, the more database tasks a system can handle.
Dual processor servers can even handle multiple databases on a single machine due to the sheer number of processing power.
These servers shine when they serve as the basis for a virtual environment or the backbone of a server cluster. This benefit does not apply to motherboards that accommodate two single-core processors.
In addition to being able to run multiple programs at once, dual processor can also work together to make a single program faster and more efficient. When programmers use multithreading, they can send different instructions from the same program into two processing paths. On a single processor with hyperthreading, the program is still limited to the maximum processing speed of the single core. On a dual core, however, this effectively doubles the speed available to that program.
