VM ID Improved Storage Usage and Performance 0

Virtual Machine Identification (VM-ID) in Fibre Channel: A Comprehensive Overview

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 2

Kata Containers, Container with VM Isolation

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.

HPE OneView Global Dashboard: Best Software for Global Monitoring

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/O Block Size (> 3 MB) Best Practice on EMC AFA/HFA and Linux (Physical and Virtual)

We have a problem on our Oracle Database servers which are hosting by Oracle Linux servers, when Oracle Databases putting to Maximum Availability protection mode, some workloads impacts performance whole database ecosystem. The workloads are related to some tasks which performed from by application servers and the tasks needs huge read/write I/O on storage arrays. We are using DELL EMC Unity/Unity XT (All Flash/Hybrid Flash) family in most of projects. I did lots of searches and found nothing at first step. I had only one clue, I/O block size was very large during performing tasks by database servers.

Windows Updates Remotely: Download and Install via PSWindowsUpdate PowerShell Module

Operating system is the core of any system and we have to keep operating system update cause of preventing performance issues, unplanned downtime and fix security vulnerabilities. Windows (client and servers) has a standard terminology for receiving updates monthly and most of organizations using Windows Server Update Services to applying updates of multiple servers/client. Updates would be downloaded and installed on multiple servers/clients automatically but service downtime is always the biggest concern but another concern is installing updates on multiple machines and rebooting systems during planned downtime. PowerShell and WinRM would help us when they come as PSWindowsUpdate PowerShell module!

CPU Core Limit in Oracle Database: Best Solution for Dummies

When you have no right sizing, when you have no control what be happened on database and when you didn’t any optimization, limiting using resources by database or any other system will necessary to help server to keep working without hang. Oracle Database be able to use all processing resources on a server and other process will be dead or hang if they couldn’t receive enough time for processing. CPU is the most important component and resource on any computer system, so if you want to stable system then the needed resources should be measured by right sizing or limiting some processes to delivering minimal resources to other processes.

pnfs architecture 3

Parallel NFS (pNFS) – Part 1 (Introduction)

Parallel NFS (pNFS) is a part of the NFS v4.1 standard that allows compute clients to access storage devices directly and in parallel. The pNFS architecture eliminates the scalability and performance issues associated with NFS servers deployed today. This is achieved by the separation of data and metadata, and moving the metadata server out of the data path.
