Nutanix is a distributed storage system that integrates storage and compute resources on physical nodes, but the logical compute Storage Fusion platform runs all of the storage logic in a pre-packaged virtual machine (Storage Control virtual machine) that runs on top of hypervisor, isolated from the business compute virtual machine, and provide high-performance storage services for business virtual machines.650) this.width=650; "Width=" 543 "height="
referring to the technological trends of storage systems, it is generally considered that hyper-convergence and Server SAN is the trend of the future mainstream, will replace the traditional storage technology architecture. So what is the technical uniqueness of hyper-fusion and Serversan ? Why can it be a mainstream trend in the future of data center storage architectures? What exactly does this architecture solve for data center problems? Where is the technical difficulty that this architectur
Over the past two years, Super fusion heat is hot. IDC the report states that - Global Hyper-converged infrastructure market growth up to 155% , . Annual market capacity is expected to grow 94% , to 2019 year will be in annual 60% the speed of growth. Nutanix/emc/vmware//Huawei/Lenovo and other mainstream it vendors have launched their own hyper-converged products. Hewlett-Packard is in the traditional cs200/cs250/cs700 and other high-end customer-o

drop-down box linkageMany sites use the dropdown box linkage, is the first drop-down box does not select any items, the second drop-down box has no options. This approach is more cautious and tighter.Below I will teach you how to do the dropdown box linkage:first assign the option to the first drop-down box in the form's Load eventAnd then the first drop-down box has an option.We then write the code for the second drop-down box in the selectedindexchanged () event of the first drop-down box (tha

The new IT wave has arrived, the Super fusion is one of many tuyere, in recent years has become the IT industry attention topic. The current hyper-fusion architecture has become the main direction of many manufacturers exerting force, the market competition is increasingly fierce. Although the concept of hyper-fusion has been hyped for at least two years, there are still a lot of vague definitions and understandings on the market, and there are differences in performance and profitability betwee
two years, with Nutanix as the representative of hyper-converged solutions more and more mature, more and more users recognize and accept HCI this way. However, in the Citrix-owned product line, XenServer, which is the most relevant to HCI, does not yet offer a solution similar to VMware Vsan, so Citrix itself is not able to provide this type of HCI solution. Based on this, Citrix leverages the ecosystem and leverages the power of its partners to add

Network latency and Complexity: Network part delay, switch configuration, compatibility, etc. cannot be ignored
Hyper-converged architectures can address these issues by changing several important components and architectures.Simply put, hyper-convergence is the integration of the traditional architecture of the network, the storage part of the software and the way the x86 server. And through the virtualization technolo
