Short and sweet: how to choose a RAID/HBA controller for the server

RAID controllers have not left and are not going to, on the contrary, hardware controllers for NVME and PCI Express drives (including M2 format drives) are entering the market. The abundance of drives and software features of RAID/HBA make you approach this choice as responsibly as possible, otherwise you may lose data. RAID controllers have not left and are not going to, on the contrary, hardware controllers for NVME and PCI Express drives (including M2 format drives) are entering the ...

Server fans: what they are, how they work

Server fans play a key role in maintaining the temperature at an optimal level. They operate at high speeds to ensure sufficient airflow within the server system, thereby cooling it. Most server fans are designed to operate at different speeds, which significantly enhances their efficiency. This means that when the server system is under load, the server fans operate at higher speeds to increase cooling, and when the load is light, the speed decreases. The main function of server fans is to ...

Review of Lenovo ThinkEdge SE50 and SE30-industrial and peripheral PCs based on Core i7 with passive cooling

These are universal computers that can simultaneously be used in production, at peripheral facilities, and are equally well suited for PC-controlled equipment, for building control rooms, laboratories, and engineering workplaces. No moving parts concept, 4G/LTE support with eSIM, DIN rail mount and RS232 ports. The development of robotics and automation of workplaces today has led to the fact that the OT industry (short for operational technologies), which includes a system for receiving ...

Article about vertical wall-mounting of servers

An interesting solution for home laboratories, small test rooms or maintenance-free points where 1-2-3 pieces of equipment are placed, and every square centimeter is worth its weight in gold I often came up with the idea: why not place servers vertically, because if you do not have a special server rack, but have a 1U-4U machine, and even a full length of 655 mm, then this bandura will take up the entire room, the entire table or rack. No, I'm not saying that server cabinets are outdated and ...

Threadripper vs. EPYC: testing three AMD 32-core processors in server applications

32 cores is where you can still get by with a 1 VMware socket license, and therefore the processor must be the fastest in the world! We will test 6 server applications, including 1C Enterprise, MySQL and NGINX, to choose the best! After the recent decision by VMware to change the licensing policy of Its ESXi hypervisor by accepting a limit of 32 physical cores per 1 processor socket, the 32-core milestone has become the front line where AMD reigns Supreme, and if today you choose a 32-core ...

What factors should be used to choose the server processor?

Why when choosing a processor, do not pay attention to the price per core or the price per Watt, but rather use the cost of a Megahertz with HT disabled and using Turbo Boost? Here's how it used to be good: for servers, there was a single Pentium Pro processor, which you didn't need to choose. With the advent of multi-core processors, it became clear that the more computing blocks, the better, but only until marketers stepped in and pided one CPU into ten sockets with ten cache options and ...

How water displaces air in Lenovo supercomputers

A couple of years ago, the maximum air cooling limit was 600W per unit. Today, it is theoretically possible to divert up to 1.2 kW per unit using air. However, in the future, you will need to allocate 2 KW, and you can't do without liquid cooling. Today, there is a steady trend to extract the maximum power from each computing unit of the data center. Users want to see more and more local disk storage inside data center nodes, and circulatory data transfer systems that combine cluster ...
