Proxmox Backup Server is a robust backup software solution designed for enterprise use. It enables you to securely back up virtual machines, containers, and physical hosts. This software is highly optimized for the Proxmox Virtual Environment platform and offers convenient web-based management, allowing you to easily handle data backups across remote sites.
VMware Fault Tolerance (VMware FT) is one of vSphere clustering features that can protect services with zero downtime but not useful for any services or any virtual machine.
This post is not about VMware Fault Tolerance capabilities and I’ll reviewing use cases. At end of this post, you’ll find why this feature is not suitable for each service or environment. Also find that when you should use it and when you should not use that.
VMFS corruption is one of disasters which happening you might lost both service and data. vSphere On-Disk Metadata Analyzer (VOMA) would help you to fix some issues on VMFS and repair metadata.
I’m sure that most IT administrators are familiar with Veeam’s products and specially, Veeam Backup and Replication (Veeam BR). This product is one of popular backup and replication suite for physical and virtual environments. Veeam Backup and Replication offers three transport modes and we’ll review the transport modes and condition of their selection in this post.
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.
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.
