VMware’s introduction of x86 server-virtualization technology was a game-changing event in the history of enterprise computing. But if you look at VMware’s corporate messaging today, it’s almost as if server virtualization has been scrubbed from the lexicon. Instead, VMware highlights its multi-cloud strategies, software-defined data centers, networking, hyperconverged infrastructures, security, SD-WAN, containers, blockchain, IoT and more.

这是呼呼的你听到，当你启动计算机或当它从睡眠模式中唤醒是您的硬盘驱动器的磁盘的开始旋转的声音。概念上没有什么不同的记录播放器，硬盘驱动器（HDD）是与致动器臂的机电装置，其自身定位在旋转磁盘，称为盘片，以读或写信息。
虽然记录players top out at 78 rpm, today’s enterprise-grade HDDs can spin at 15,000 rpm. Even at that speed, however, there are unavoidable delays associated with heads finding the spot on the drive that contains the data being requested. And sometimes a drive may need to read from multiple locations in order to complete a command, multiplying wait times.

动态主机配置协议（DHCP）是在IPv4网络的标准方式的网络管理员分配IP地址，但最终组织将具有专门为IPv6的创建为两种协议之间来接使用这种新的IP协议的增长。
DHCP，这可以追溯到1993年，是分配IPv4地址的自动方式，但IPv6的设计时，它被提供有被称为SLAAC，一个自动配置功能最终可能使DHCP无关。麻烦的是，新的DHCP - 的DHCPv6 - 执行如SLAAC为IPv6是独立创建的相同的功能 <一边类= “fakesidebar”> <强> [现在读 20个热门职业雄心勃勃的IT专业人员应该打一枪换。]
Deciding between SLAAC and DHCPv6 isn’t something admins will have to do anytime soon, since the uptake of IPv6 has been slow, but it is on the horizon.
Server virtualization is one of those technologies that’s simple in concept and profound in its impact on enterprise data centers.
What if, instead of running one operating system instance and one application per server, you could add a layer of software, known as a hypervisor, that enables you to run multiple operating system instances and associated workloads on a single physical server?
That’s the idea behind server virtualization, and the idea dates back to IBM mainframes in the 1960s and was popularized by VMware, which introduced virtualization software for x86 servers in the early 2000s. Since then, other vendors have developed their own server-virtualization platforms and the industry as a whole has created advanced management, automation and orchestration tools that make deploying, moving and managing virtual machine (VM) workloads a breeze.
Virtual desktop infrastructure (VDI) is one of those tantalizing technologies that looks great on paper, but hasn’t gained much traction over the years for a variety of financial, technical, cultural, even philosophical reasons.
However, a relatively new framework called hyperconvergence, which combines compute, storage and networking in a single data center appliance, could breathe new life into VDI by reducing the cost and complexity associated with a VDI rollout.
The argument in favor of VDI, also known as desktop virtualization or thin-client computing, makes perfect sense.
