This year marks Selectel’s 10-year anniversary! We’re so excited that we’ll be celebrating all year. Let’s kick it off by looking back to what life was like when the company was first founded. Below are some of the biggest events we can remember happening about ten years ago (warning: reading the following list might make you feel old). Read more
Select has launched a new service for creating VMware-based public, private, and hybrid clouds: VMware Cloud. Read more
Today we’ll be publishing a guest post, co-authored by Konstantin Boyandin, a system administrator from Novosibirsk.
Konstantin worked with in-memory databases (memacached, Redis, Apache ignite, etc.) on a server built with an Intel Optane SSD. The specific device tested was the Intel Optane SSD DC P4800X and was connected using IMDT (Intel Memory Drive Technology), which made the drive available to the OS and applications as RAM. Read more
We regularly publish articles on the latest processors from Intel, which for many year has maintained its position as the market leader of server solutions. However, the situation has been changing as of late and other players have actively been making a name for themselves. This past March, AMD released it EPYC processor family, which has received some interesting and generally positive reviews (like this article on Anandtech). Seeing and trying something for yourself though often proves more valuable than reading (even hundreds) of articles online. Read more
For an operating system and all of its services to run smoothly, the system clock has to be accurate. If it’s off by just a few seconds, the results could be disastrous. Read more
Just over two years have passed, or rather flown by, since the grand opening of the Tsvetochnaya 2 data center. In our article covering the event, we not only shared photos from the festivities, but briefly looked at the data center’s infrastructure. We soon started thinking that it’d be a great idea to publish a series of articles that take a more in-depth look at these systems. Well, we’ve finally managed to take a break from our day-to-day and put our plan into action.
At the heart of it, the operations of any data center rest on three pillars: power, cooling, and security. Without a doubt, the key system here is power. Read more
Despite how new something is or how long it’s been working under a full workload, equipment sometimes starts to act a bit unpredictably. Servers are no exception.
Crashes and malfunctions happen, and oftentimes, what should just be simple troubleshooting turns into a time-consuming whodunit.
Below, we’ll be looking at a few interesting and curious examples of how servers have misbehaved, and what was done to get them back in order. Read more
The 11th annual HighLoad++ conference was held from November 7-8 at the Skolkovo Innovation Center. This year, the conference saw 2 700 people in attendance—200 more than last year! Today we’ll be reporting on the highlights and presentations that our team from Selectel saw. Read more
We’ve added a new function to The Virtual Private Cloud to make managing virtual machines even more convenient and cost-effective: workload statistics.
Users can now view graphs on the workloads of virtual machine components from the control panel or gather measurement data over REST API.
In this article, we’ll talk about the components used for gathering, processing, and storing virtual machine metrics as well as give examples of how these components can be configured. Read more
