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.
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.
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!
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.
EMC has released new OE (5.2.0.0.5.173) for Unity/Unity XT storage array family with new major changes. The new release also contains lots of resolved issues for different components. The biggest changes are “Data Reduction and Advanced Deduplication” can now be enabled for hybrid storage pools and also dynamic pools will be expanded faster than before.
As the world’s leading provider of Software-Defined Storage, High Availability, and Disaster Recovery software, LINBIT adds server clustering capabilities to any containerized, virtualized, or bare metal environment.
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.
Ceph is most popular software-defined storage platform and offers Objec-Storage, Block Device and File System (CephFS) for storing data in modern data centers or public and private clouds. Best and popular solutions needs alternatives as well. So at this post, we’ll review some alternatives for Ceph.
Windows OS Optimization Tools was a VMware’s Fling and this free tool has been productized now. Windows “OS Optimization Tool For VMware Horizon” will be official Horizon’s components from VMware Horizon 2111. What’s Windows OS Optimization Tool for VMware Horizon? The Windows OS Optimization Tool for Horizon makes it easy to apply configuration settings to desktops and servers. It includes settings to optimize the following Windows operating systems for both desktops and servers that reside in the data center and in the cloud: Windows 11 Windows 10 Windows Server 2022 Windows Server 2019 The Windows OS Optimization Tool for Horizon optimizes virtual desktops and RDSH servers for Horizon, and Horizon Cloud. Notes: The Windows OS Optimization Tool for Horizon is not compatible with Windows 7, 8.1, Server 2012, Server 2012 R2, and Server 2016. An older version of the OS Optimization Tool (b1130) is available to download from the VMware Flings site to use on these OS versions. The optimization information in this guide does not pertain to Windows XP or Windows 7, which Microsoft no longer supports. For more information, see the Windows XP Deployment Guide. The Windows OS Optimization Tool for Horizon helps with three key steps in this process: Optimize...
EMC Unity array was released in 2016 to replace VNX and VNXe family with another mid-range array solution. EMC Unity came with lots of new features and enhancements compare to older families but there was an absent feature that VNX offering. Host access method was changed and each LUN should have been present to each host separately. More than 4 years from GA release, we were waiting for changing host access method because presenting LUN to each host was horrible in large scale environment with many hosts and LUNs. Biggest Change In EMC Unity OE 5.1.0.0.5.394 Previous versions have “Consistency Group” with some limits to present a LUN or more than one LUN to group of hosts. EMC Unity OE 5.1.0.0.5.394 including new feature that the new feature is like VNX Storage Group. The new feature called “Host Group“. You could assign or present multiple LUN to multiple hosts in OE version 5.0 and later but Host Group is the feature that we want. In Dell EMC Unity OE version 5.1 users can logically group hosts and block resources within a host group. Host groups can be created and managed from the Host Groups tab and help to streamline host/resource...
Unity XT storage arrays are designed for performance, optimized for efficiency and built to work in multi-cloud environment. Actually Unity XT storage array is mid-range storage array family but this family is capable for enterprise workloads. Enterprise businesses needs protection and needs business continuity solutions. Typically, mid-range storage array has no native business continuity solution but Unity XT offers Unity XT Metro Node as business continuity solution.
Alpine Linux is an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency. Alpine Linux is “Small, Simple and Secure”.
Each workload needs to proper processor for processing, some workloads need to more cores and threads and some workloads need to more power. Today, Data Centers are changing and workloads as well. Applications are moving to Cloud Native platforms and virtualization needs more density instead of processing power. Arm (Advanced RISC Machines) is going popular for cloud workloads and server products because ….
