A NIC team can share a load of traffic between physical and virtual networks among some or all of its members, as well as provide passive failover in the event of a hardware failure or network outage.

To utilize NIC teaming, two or more network adapters must be uplinked to a virtual switch. The main advantages of NIC teaming are:

  • Increased network capacity for the virtual switch hosting the team.
  • Passive failover in the event one of the adapters in the team goes down.

Cloud Storages and AcloudA

In recent years, more and more popular use of cloud technology. They are used in business processes, web hosting, telecommunications services, in software development and testing, for private use and much more. The main advantage of using cloud technologies and the reason for their ubiquitous distribution is the lack of the need to have a powerful computing system for the end user, which unambiguously leads to a significant cost reduction for business or ordinary end users. In addition, the cloud services provider takes care of the work of the system and applications, provides technical support to users, installs updates on its own and upgrades the computing servers and storage servers. Thus, the user is less concerned with technical issues related to the operation of the system and he can focus on his goals.

As part of the cloud infrastructure, cloud storages can be distinguished.

Building a Cluster based on VMware (part I)
Posted by Veniamin Kireev on January 29, 2018

To build a cluster, VMware uses from 2x to 32x ESXi servers that are managed using vCenter. To build a cluster, you also need a shared store. It can be implemented with VMware vSAN or with storage support providing access via Fiber Channel, iSCSI or NFS. The storage stores the virtual machine files that are available to all the cluster hosts at the same time. It is due to the overall storage and independence of the virtual machine from the physical platform that rapid migration/recovery of virtual machines is achieved.
