I’ve published many articles about STOR2RRD and LPAR2RRD monitoring software for monitoring servers, OS, storage, SAN, LAN and other devices. XORUX has released new version of the monitoring suites with new features and capabilities. Let’s review the new features, capabilities and changes.
Enterprise businesses such as banking business using latency sensitive applications. Most of application delay issues are related to network infrastructure. Also most of application server are Linux servers. How can we measure network latency on Linux?
We are all knowing LACP on ethernet network but Fibre Channel and SAN network providing multipathing I/O by using logical and physical paths as single device on operating system and also using path selecting policies for using I/O paths optimized. But if server using 16Gb/s FC HBA, so there is no bandwidth aggregation. Server can generate bandwidth for each port up to maximum speed of port and also path selecting has performance impact of server when large paths are presented to server. Months before, I was thinking about FC port aggregation and did many searches but I didn’t find anything until now.

During virtualization revolution, physical servers replaced with virtual machines to run multiple different workloads on a single server hardware but virtual machines were still large and needs some resources to run as isolated servers. Virtual machines needs to have their own operating system and applications. Also they needs to manage and configure separately. MicroVM or Micro Virtual Machine offering benefits of two different technologies and Firecracker will help you to implementing MicroVM.
I am really fan of what is doing Oracle for Oracle Linux and offering open-source solutions with free update. Oracle Linux Manager is one of free and open-source solutions that Oracle provides for Oracle Linux by developing new enterprise solution from open-source solutions.
I met HPE C7000 more than ten years ago for first time and I was newbie engineer in virtualization and datacenter. We had 6th generation of blade servers and the first virtual desktop infrastructure farm hosted by the servers in Iran and even Middle East. Now I didn’t find any official information about HPE Blade System retirement but after BL6xx server are retired and BL4xx servers released by some limitation compare to Synergy servers, it was clear.
Windows is still most popular operating system for clients and many administrators using Windows as client to managing infrastructure. But the administration needs to interacting with some Linux servers or other systems that using OpenSSH server as connection gateway for accessing to shell.
You may using HPE OneView for monitoring your HPE infrastructure, if see this warning on your server health, follow this post:
Overall security state of the system is at risk
HPE is on of biggest companies which producing data center equipment’s and facilities. HPE has unified management and monitoring suite for server hardware, network devices and storage devices that called HPE OneView. You may have multiple data center at different geographical location and needs to monitoring all devices on same dashboard. Because HPE OneView needs access to any under managed devices via network and it’s recommended that implementing HPE OneView in local site, there are some limitations about managing and monitoring all devices on single instance of HPE OneView. HPE has introduced HPE OneView Global Dashboard for monitoring and managing multiple HPE OneView appliances.
I’m not a developer or software designer but as an user, I need to Single Sign-On for web applications that those made for a software solution. Some companies developing their solutions on this regard but Keycloak already developed and available as open-source software.
