FC Port Aggregation (Trunking) 0

Fibre Channel (FC) Trunking (Port Aggregation) on Servers, How It’s Possible?

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.

HPE BladeSystem Retirement

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.

What’s HPE OneView Global Dashboard?

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.

Network Connection Problem on HPE FlexFabric 650 (FLB/M) Adapter

We have many HPE Blade System C7000 chassis for hosting our virtual infrastructures or our customers virtual infrastructures. Also many of them are filled with HPE ProLiant BL460c Gen10. Recently, we had serious problem with some of the servers about network connection, if there was FlexFabric 650 (FLB/M) adapter installed on blade server. What’s Exact Problem? Our servers were working fine but after a while, we lose our vMotion network connectivity, the hosts couldn’t migrate virtual machines even between servers in same C7000 chassis. The problem was happened on one chassis and other chassis has no problem. Network adapter was...

Intel Hyper-Threading vs AMD EPYC SMT

In the past but not so long, just before 2001 and before design first multi-core CPU, processors had one core. Intel, AMD and others they tried to increase transistors and frequency in processors. Result of one core CPU was processing single thread at time, the thread might not took all CPU time. Multi-Core processors and multi-threading helping to processing more than one task or process at a time. Today, processors have more cores and also have features to doing multi-threading. Join me to review Intel Hyper-Threading and AMD SMT. Intel Hyper-Threading Hyper-Threading Technology is a form of simultaneous multithreading technology introduced by...

Optimized Setting for VMware vSphere on HPE G10 Servers

Optimizing server configuration is always one of biggest challenges for virtual environments administrators. The administrators always trying to provide best performance by changing configurations on hypervisor, virtual machines or other components or virtual infrastructure. There are best practices which published by server vendors to achieve best performance on their server platform. Server hardware is one most important components in every environment, server provides main power and resource: Computing Resources. Processor and memory and other server’s component made to work almost like as human brain. Some Important Things! Human brain needs consumes about 20 percent of the body’s energy. Consume more...
