Hard-drive failure rates tied to age in latest Backblaze analysis

Cloud backup and storage provider Backblaze released its latest annual report dissecting hard-drive failure rates, and it’s clear that age is a key determinant of a drive’s potential for failure.Backblaze has become something of a go-to source for hard-drive durability, thanks to its quarterly analysis of its own fleet, which included 231,309 hard drives used to store data as of December 31. (After excluding drives used for testing purposes and low-count models, Backblaze analyzed 230,921 devices for its report.)To read this article in full, please click here

Improve BGP Startup Time on Cisco IOS

I like using Cisco IOS for my routing protocol virtual labs1. It uses a trivial amount of memory2 and boots relatively fast. There was just one thing that kept annoying me: Cisco IOS release 15.x takes forever to install local routes in the BGP table and even longer to select the best routes and propagate them3.

I finally found the culprit: bgp update-delay nerd knob. Here’s what the documentation has to say about it:

IBM denies suggestion that AIX being deprioritized

IBM disputes a report that it has de-emphasized development of its Unix-based AIX operating system by moving development to India and said that it remains committed to the venerable OS.Commentary in The Register said AIX development had been transferred to India with a sub-headline not to expect "any more big AIX news." IBM’s response is that there has always been AIX development in India, and U.S.-based talent remains at work on the Power platform, which runs AIX.“For this transition, every single person that was on my US team on the day that we announced this was mapped to a new role where we needed them to help us next,” said Mark Figley, vice president of IBM Power development. To read this article in full, please click here

Fortinet unveils custom ASIC to boost firewall performance, efficiency

Fortinet is introducing a new ASIC that promises to meld the security and network functions of its core family of FortiGate firewalls more efficiently and powerfully.The custom chip is 7-nanometer package, called fifth-generation security processing system or FortiSP5, that promises a number of performance improvements for the FortiGate system. It enables 17x faster firewall performance and 32x faster encryption processes while using 88% less power compared to standard CPUs, according to John Maddison, executive vice president of products and CMO at Fortinet. With FortiSP5, Fortinet's firewalls will be able to handle higher levels of traffic inspection to block threats and boost protection, according to the vendor.To read this article in full, please click here

Manipulating text with awk, gawk and sed

The awk, gawk and sed commands on Linux are extremely versatile tools for manipulating text, rearranging columns, generating reports and modifying file content.Using awk and gawk To select portions of command output using gawk, you can try commands like those below. The first displays the first field in the output of the date command. The second displays the last field. Since NF represents the number of fields in the command output, $NF represents the value of the last field.$ date | awk '{print $1}' Sat $ date | awk '{print $NF}' 2023 Note that on Linux systems today, awk is usually a symbolic link to gawk, so you can type either command and get the same result. Here's what you'll probably see when you do a long listing of the awk executable:To read this article in full, please click here
