Performance or protection? How Microsoft patches against Meltdown and Spectre influence CPU, RAM and Disks performance

In today’s topic, I’d like to talk about the Meltdown and Spectre vulnerabilities. But not about the harm they cause, this has been covered widely in numerous articles, but how Microsoft patches intended to protect you from the vulnerabilities, affect (if they do) the hardware performance. Before we take a deep dive into the tests and numbers, let me tell a few words about Meltdown and Spectre and outline the testing scope to make sure we speak one language.

Shopping for HDDs? My notes on how to do it right

It goes without saying that hard disk drives (HDDs) are one of the most common storage medium to date. Data centers, home labs, and PCs have them inside. No wonders, HDDs offer unmatched capacity for moderate costs per GB. Let’s take a closer look at how to choose an HDD. This article is going to be pretty much a long read, but there’s a flow chart in the end that helps to make your choice.

Integrating StarWind Virtual Tape Library (VTL) with Microsoft System Center Data Protection Manager

The reason for writing this article was the goal of eliminating any possible confusion in the process of configuring the StarWind Virtual Tape Library in pair with the Microsoft System Center Data Protection Manager. The integration of SCDPM provides a benefit of consolidating the view of alerts across all your DPM 2016 servers. Alerts are grouped by disk or tape, data source, protection group and replica volumes, which simplifies troubleshooting. The grouping functionality is further completed with the console capable of separating issues that only affect one data source from problems that impact multiple data sources. Alerts are also separated into backup failure or infrastructure problems.

RAM Disk technology: Performance Comparison

Since every computer now has a volatile amount of available storage located in the RAM, when compared to other direct-access memory used for data storage, for example, hard disks, CD-RWs, DVD-RWs and the older drum memory, the amount of time used to read/write the data differs in correspondence to the physical location and/or the medium used for reading/recording (rotation speeds and arm movement) the data. The implementation of RAM as a storage provides a list of benefits over other conventional devices, due to the fact of the data being read or written in the same amount of time irrespective of the physical location of data inside the volume. Taken into consideration all the information mentioned above, it would be a crime not to take advantage of the provided conditions.

RAID: Parity RAID vs SSD

The post describes the history of RAID 5 and how it became obsolete at some point in time, just because HDD capacity grew at an enormous rate. It happened due to the chance of failure that grew to literal imminence when spinning disks reached TB scale, because the reading speed still had the same physical limits. Basically, creating a RAID 5 even with 1 TB disks would mean certain failure of the whole array and quite soon. The array technology was “saved” by an unlikely ally – the SSD. Being faster than hard disk drives in everything, they almost nullify the chance of the abovementioned failures. The post is written for everyday reader, not just engineers, and is quite comprehensive even without special knowledge and skills.
