How VMware vSphere 6.0 is Better than VMware vSphere 5.5

How VMware vSphere 6.0 is Better than VMware vSphere 5.5

Undoubtedly there’s an increasing number of people getting inclined towards virtualization. Since the sounds of benefits of virtualization to business and technical fields are heard from the mountain tops by several entrepreneurs, it has become a significant element for all.

Being an innovative technology, virtualization helps organizations to cut the costs on various aspects and operate more efficiently. Big companies with great IT resources took the initiative to implement it. But today, even small and medium size businesses are joining the bandwagon. Do you know how virtualization can help your business to boom?

Here are benefits of virtualization to business –

  • » Businesses can run multiple operating systems and applications on a single machine which leads to requirement of less number of physical servers which saves your hardware costs.
  • » Less use of hardware means there will be less usage of power that leads to reduced maintenance and energy costs.
  • » Managing physical and virtual environments holistically together in the same manner is important for reducing complexity and risks while enhancing productivity. Virtualization simplifies management of IT along with maintenance and deployment of apps.
  • » Virtualization is one of the best solutions for productivity as it enables quick and easier backups along with disaster recovery.
  • » When you adopt virtualization in your venture, opting for external, internal or hybrid cloud services becomes easily possible.

There are several virtualization solutions you can select from – VMware, IBM, Citrix, Pertino and Symantec and more. But one of the most popular within the businesses is VMware. VMware is one of the pioneers of virtualization industry that offers a wide range of products and services that help in cost reduction of IT and easy management of all types of businesses. The end-to-end solution of VMware is vSphere with Operations Management, a virtualization platform popular for its reliability and used by businesses globally. vSphere provides powerful computing that enables handling of multiple workloads with less downtimes and optimum performance. In addition, simplified network services and administration, efficient storage systems, consistent IT task automation and robust security to protect users’ data and applications.

Recently, VMware unveiled its new version of vSphere that is vSphere 6.0 which is the updated version of vSphere 5.5. You might be excited to uncover the additional features in vSphere 6.0 that were lacking in vSphere 5.5. So, here’s the difference between the two –

Scalability –

VMware ESXi 6.0 has expanded the scalability of the platform to a great extent. vSphere Hypervisor 6.0 clusters enable scaling up to 64 hosts, up from 32 hosts in vSphere Hypervisor 5.5. vSphere 6.0 can support around 8,000 virtual machines in a single cluster, enabling increased efficiency in using VMware vSphere Distributed Resources Scheduled (vSphere DRS), extended consolidation ratios and only few clusters that require separate management. A single vSphere Hypervisor 6.0 will now support around 480 CPU, 12TB and 1000 virtual machines. Virtualization of applications that were thought to be non-virtualizable is now possible with ESXi 6.0.

Fault Tolerance Enhancements –

VMware vSphere Fault Tolerance is a feature that offers continuous availability for applications when the physical server fails by creating a live shadow of a VM that is always upgraded with the primary virtual machine. When there is a hardware outage, a warning of failover is automatically given by the Fault Tolerance ensuring uptime and preventing data loss. In the vSphere 5.5 version, vSphere FT was supportive to a single virtual CPU. The new fast check pointing technology in vSphere FT facilitates safety of around 4 virtual machines and 64GB of memory. With this innovative feature, there isn’t any need of application or OS for protecting great mission-critical customer workloads. In vSphere FT 6.0, vSphere administrators can take the backup of virtual machines protected by vSphere FT by using VMware Snapshot-based tools that enables enhanced data protection, easier backup administration and reduced risk.

Storage –

A new virtual machine disk management and integration framework, Virtual Volumes is introduced in the vSphere 6.0 which enable array-based operations at virtual disk level. Transformation of data plane of SAN and NAS storage systems is done by alignment of storage consumption and operations with virtual machines. The storage system becomes storage centric with the way storage is presented, managed and used by vSphere/ESXi with the implementation of virtual volumes.

VMware vSphere High Availability Enhancements –

The key role of vSphere High Availability (HA) is to deliver the availability required by several applications running in virtual machines, independent of the OS and application running in it. It monitors the vSphere hosts in the cluster with any manual intervention when there is a server outage, thus providing uniform and cost-effective failover protection against hardware and OS outages within a virtualized IT environment. It can now safeguard around 64 ESXi hosts and 6,000 virtual machines – up from 32 ESXi hosts and 2,048 VMs. In addition, it is completely compatible with VMware vSphere Network I/O Control, VMware Virtual Volumes, IPv6, VMware NSX and cross vCenter Server vSphere vMotion.

Multisite Content Library –

A centralized and distributed location to store handy files required during installation as well as maintenance of infrastructure is referred to as multisite content library. For instance when a new VM is being installed, there is requirement of an ISO-file on central data store. Several administrators keep their own copy that overloads your infrastructure with all versions and duplicates of same content. But with vSphere 6 Content Library, the replica of this library can be created at another vCenter Server at the remote site.

vSphere Networking Enhancements –

Now the administrators or service providers can guarantee bandwidth to vNIC in a virtual machine or an entire distributed port group. With this enhancement, it is ensured that there would be no impact of other virtual machines or tenants in a multitenancy environment on the SLA of virtual machine or tenants sharing upstream links i.e. bandwidth.

VMware vSphere vMotion –

The new vSphere vMotion enables users to perform live migration of VMs across vCenter Server systems, across virtual switches and across long distances that is up to 100ms RTT. It means with these enhancements, users will get greater flexibility while designing vSphere architectures that were restricted to single vCenter Server system in vSphere 5.5. vMotion across vCenters will simultaneously change storage networks, compute and management which is leveraged with unshared storage and will support local, metro and cross-continental distances. Prior to vSphere 6, vMotion required Layer 2 connectivity for the vMotion network. vSphere 6.0 enables performance of vMotion with the use of routed vMotion networks.

There is more to add to the list but these are few major updates included in VMware vSphere 6.0. Hope the VMware vSphere 6.0 would prove more beneficial as compared to its prior versions. To research more on it, you need to wait until the GA is released. So, stay tuned for more updates.
