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.
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.
