In my previous post on RAID-5, I talked about how we can recover the data using simple additions and subtractions. We will discuss RAID-6 in this post. Unfortunately, you need a bit more than additions and subtractions to understand how we recover data in RAID-6. Toward the end of this post, I will touch briefly upon the "finite field," but I will refrain from being too mathematical. Index: Recap Why Do We Need RAID-6 Is Single Parity Useless? Assign Numbers For Each Drive...

Things break. So are the hard drives and SSDs. We are storing our important data on devices that we know they eventually break, so we need some protection. We use RAID technology for granted without knowing much about its internals. This post is an attempt to explain how RAID-5 recovers data by using elementary school math. Understanding the internal will help you understand why the RAID layout with a lot of drives would take longer to recover data. In this post, I...

We're pleased to announce that Oracle Solaris 11.4 images are now available in the Oracle Cloud Infrastructure (OCI) Marketplace! This means that customers of OCI IaaS can run Solaris workloads in the cloud with full support from Oracle, which is included in your IaaS subscription. There are two images, one for bare metal and another for virtual machines, and they're available in all OCI regions. Using the Solaris images is very simple. In the OCI console, select the...

In my previous blog on the REST API in Oracle Solaris I showed how you can enable the remote REST interface on Oracle Solaris and connect to it. I also mentioned the REST API is layered on top of the Remote Administration Daemon (RAD) so it gives you access to all its modules. In this blog I wanted to highlight the IPS RAD module and how you can use it through the REST interface to do some common IPS tasks using it. Where in the previous blog I showed the initial REST calls...

One of the things that makes Oracle Solaris unique is how easily and transparently it can deal with different memory page sizes, officially Multiple Page Size Support (MPSS) introduced eons ago in Oracle Solaris 9. This to say the support for using larger memory pages than the standard page size (4KB on x86 and 8KB on SPARC). Anything larger than this smallest page size is seen as a "Large Page". The reason these large pages are important is for performance. As systems grew...

This blog is intended as an introduction to managing Oracle Solaris 11 through a REST interface, that is to say, managing it through http/https GET/PUT/POST/DELETE commands. Over the last few years the REST API has become a very popular way to talk to/manage services on the network. This is in part because pretty much anything can talk http/https — read: can talk over http/https and/or has an http/https server built in — so you can equally talk to and between applications,...

To make sure you're not missing out I'm giving a quick heads-up on some good technical content. So, over the last few months we held a few technical Oracle Solaris events, one virtual and two in person. (I had talked about this is a previous blog.) The first, a Virtual Seminar on Continuous Innovation in Oracle Solaris 11.4, was held on April 25th, and even though it was well attended in live form we wanted to make sure you know that the recording can still be viewed, even if...

In the coming months we have some really nice in person events coming your way. First thing I wanted to mention is that we will be holding two Oracle Solaris TechDays in on April 29th in Dubai and on May 14th in Prague. These TechDays are all day events with in-depth presentations and demonstrations on various Oracle Solaris technologies and features, and how to use them. What also makes these TechDays special is that the presentations are given by Bill Nesheim -- the VP of...

Guest Author: Petr Sumbera As you may know, a new OpenJDK 12 was released which you might want to try on Oracle Solaris. There are already some great blog posts out by Martin Mueller and Andrew Watkins describing how to build recent OpenJDK versions from sources. But there is an issue. To build OpenJDK you will always need previous version as a boot JDK. Basically to build OpenJDK 12 you will need OpenJDK 11 and so on. For SPARC it's rather easy as you can download Java SE...
