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...

HPE FlexFabric 650FLB Adapter May Cause PSOD on ESXi 6.x

Seems, there is an issue on HPE Blade Servers when a specific adapter is installed on server. If there is any server of the below models in your virtual environment that you should consider to this post: HPE ProLiant BL460c Gen10 Server Blade HPE ProLiant BL460c Gen9 Server Blade HPE ProLiant BL660c Gen9 Server HPE servers running VMware ESXi 6.0, VMware ESXi 6.5 or VMware ESXi 6.7 and configured with an HPE FlexFabric 20Gb 2-port 650FLB Adapter with driver version 12.0.1211.0 (or prior), a “wake NOT set” message is logged in the Vmkernel logs. Then after 20 to 30 days...

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...

Change Administrator’s Password for All HPE C7000 Device Bays

HPE C7000 Blade System using Onboard Administrator (OA) KVM module to manage devices and interconnects in chassis. To manage devices directly, OA will redirect to iLO of each device. OA use single sign-on to logon to iLO administration web page. But each server has own administrator user and the user has default password, so if iLO addresses are reachable via network, it’s better to change default password. Think about two or more C7000 chassis with half high blade servers, changing password on 64 servers would be difficult! Onboard Administrator has builtin tool to configure device bays iLO. HPONCFG can change...

Using Network Partitioning (NPAR) in VMware ESXi

Data Center design is changing year by year, before virtualization all servers was physical and data centers were full of devices and cables. Virtualization helped to make data centers smaller and consolidate different workloads in same hardware. Hardware technologies are also helping to achieve this goal. Network Partitioning (NPAR) is one of hardware technologies which helping to reduce cabling, switch devices and use all I/O capacity in data centers. What’s Network Partitioning (NPAR)? NPAR is an operating system and switch agnostic technology that allows customers to reduce the number of I/O adapters required to support different application workloads. Traditional best...

HPE Fast Fault Tolerance 2

HPE Advanced ECC Support vs HPE Fast Fault Tolerance

Memory failure is one of reasons that can be cause of server crash and impact on service availability and performance. Think about a service which including multiple servers, server could be crashed cause of single memory module failure or uncorrectable memory error. Regarding to preventing memory impact of memory errors on services, HPE provides RAS technologies. RAS (reliability, availability, and serviceability) technologies are including: HPE Fast Fault Tolerance Advanced ECC support Online spare with Advanced ECC support Mirrored memory with advanced ECC support In this post, we’ll compare HPE Fast Fault Tolerance and HPE Advanced ECC Support. Before comparison, let’s...

HPE Synergy Cabling Guide

HPE Synergy is a next‐generation data center architectural option, Composable Infrastructure embraces and extends key concepts and traits from the architectures that have come before it, including converged and hyperconverged systems. I don’t know when but seems that HPE will replace HPE Blade System with HPE Synergy in future. Those who worked with HPE Blade System, will confuse about HPE Synergy configuration. Configuration is very different with Blade System at all. Cabling is one of biggest challenges with HPE Synergy. There is many management connection which should connect to the correct ports. Because HPE Synergy is a composable infrastructure so...
