A data center (American) or data centre (British) is a building.
Dedicated space within a building or a group of buildings used to house computer systems.
Virtual Machine Identification (VMID or VM-ID) is a technology for tracking virtual machine I/O between virtual machine and SAN target. VM-ID can be used by hypervisor and FC switch to trace generated I/O by specific VM. As result, we can optimize whole SAN area for VI workload and non-VI workloads would be achieved.

Kata Containers offers method of container deployment with more security. Security is one biggest challenge about containers and containers has lower level of security compared to virtual machines. Because virtual machines are isolated from each other, but containers can’t provide isolation same as virtual machines.

SmartOS is a live OS. What does it mean? SmartOS always boot from removable media and network. There is no need to use disk capacity for itself.
Lockdown mode could be useful to achieved maximum restriction to ESXi hosts. Let’s decide to activate lockdown mode in VMware vSphere together at this post.
DELL EMC PowerProtect Appliance has two types currently. We’ll review difference between two types at this post.
Virtualization platforms such as VMware vSphere or Linux KVM supporting large scale of virtual machines now. Even, virtualization platforms can host monster virtual machines as database server. At this post, we’ll review database backup solutions in virtualization platforms about advantages and disadvantages.
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.
