Introduction to the features and version upgrades of VMware Vsphere6.0

Introduction to the features and version upgrades of VMware Vsphere6.0

When it comes to VMware's products, it is believed that everyone is already familiar with the VMware from the very first contact

Workstation to today's VMware vsphere products, VMware Workstation has now been updated to version 11.0, the same VMware Vsphere has been updated to 6.0, and I'm not going to introduce you to workstation, and today, I'll focus on the latest features of VMware vsphere 6.0, as well as VMware vsphere5.5 for functional comparison, mainly I simulated my real environment, my previous environment is the VMware vsphere5.5, used for a period of time to go, during the operation of the VM to find the vsphere host error caused the service failure, and finally the VMware Vsphere has upgraded from 5.5. To vsphere 6.0, there are three ways to upgrade VMware vsphere: 1, upgrade ESXi, preserve VMFS format and data. 2. Install ESXi, preserve VMFS format and data, but lose configuration and need to rejoin the virtual machine to the inventory. 3, new installation, all data are not retained. For different modes of operation can be selected according to their own environment, operation summary after sharing to everyone, specifically see below:

First, compare the features of VMware vsphere5.5 and VMware vsphere6.0. See what new features appear in VMware vsphere6.0.

1. TB VMDK

2. Support for Gbps end-to-end FC

3. PDL automatically deletes

4. Improved VAAI UNMAP (now using ESXCLI)

5. VMFS Heap Improvements

6. VFlash Read Cache (VFRC)

7. Provide MSFT cluster support for FCoE and ISCSI

8. You can rename a virtual machine file in Storage vMotion

9. vsphere Replication, Storage vMotion, and Storage DRS interoperability

10. Compatible with virtual SAN (Vsan)

One. VSphere Replica tion

12. Multi-Site topology

13. Support Storage vMotion

14. Multiple point-in-time (mtip) snapshots

Summary See below:

One, scalability:

1. A single virtual machine supports 128 virtual CPUs (Vcpus) and 4T of virtual memory (VRAM);

The 2.ESXI host supports 480 CPUs and 6TB RAM (RAM);

3.ESXI host supports 1024 virtual machines (VMS);

4. The cluster supports 64 nodes.

Second, storage

1.vSphere virtual Volumes enables your external storage arrays to recognize VMS;

2. Storage Policy-based management allows for universal management and automation of dynamic storage class services across storage tiers.

third, the network

1. Support per virtual machine and distributed switch bandwidth reservation to guarantee the lowest service level.

iv. Availability: vMotion Enhanced Features

1. Migration workloads can be implemented across distributed switches, VCenter Server, and roundtrip up to 100ms non-disruptively;

2. Long-distance vmotion migration, so that round-trip time is increased by 10 times times;

copy-assisted vMotion Migration

1. Customers with active replication between two sites are able to perform more efficient migrations, thus saving significant time and resources. The second is fault tolerance: 1. Supports up to 4 virtual CPUs (Vcpus), extending support for software-based workload-tolerant functionality.

v. Management: Content Library

1. A central repository for simple and efficient management of content, such as virtual machine templates, iOS images, and scripts, allows users to use the Vsphere Content Library to store and manage content from a centralized location, as well as share content through a publishing or subscription model.

across VCenter for cloning and migration.

1. A single operation can clone and migrate virtual machines between hosts on different vcenter servers.

Let's start with a new installation of VMware vsphere5.5

Select Upgrade Method: 1, upgrade ESXi, preserve VMFS format and data. 2. Install ESXi, preserve VMFS format and data, but lose configuration and need to rejoin the virtual machine to the inventory. 3, new installation, all data are not retained.

In general we will choose the default (1) to upgrade.

We then compared the installation of virtual machines with VMware client, and found that there were many additions to the version of the virtual machine that were not available at VMware vsphere5.5. Figure 1 is 5.5, Figure 2 Bit 6.0
