VMware Generation 6: VMware Genx6

VMware has finally announced the VMware’s 6th generation virtualization  software in month of Feb 2015 though GA is not announced(When writing blog).  From the very first release of vCenter in 2004. VMware has climbed the height of success and leading the market with most stabilized and advanced product made in the world of Virtualization. Eric Siebert in his blog collected all the stages of VMware History, can be found @ VMware release.

With my previous blog VMWARE VSPHERE 6: WHAT TO EXPECT “VMWARE DORAEMON”  not completely but few component where seen in Beta release like FT.   Not saying that VMware has considered my blog but it was a technology where we has not seen any improvement from  past few years.

With the Generation 6 launch, new product set are lined up with vSphere 6, VDP 6, vSAN 6.0, vSphere Replication and more VMware has again created the benchmark for other Vendors and forced Microsoft to release their next version of Hyper-V soon. From the trend Windows 2008 to 2012 took approx 3-4 year resulting current version of Hyper -V. Where as VMware has become like iPhone, every year new product lineup. Big question is how many big organization are going to put their production workloads after GA announcements . Many Vendors are still running 4.x or 5.0 workloads.

Lets see what VMware has served as this time,

VMware vSphere 6.0

Till now VMware has not officially released the VMware Max, which is most searched VMware documents by architect.

Compute: Talking of Compute, VMware has improved the scalability of VM saying Virtual machines will support up to 128 virtual CPUs (vCPUs) and 4TB virtual RAM (vRAM). Hosts will support up to 480 CPU and 12TB of RAM, 2,048 virtual machines per host, and 64 nodes per cluster. Expanded support for the latest x86 chip sets, devices, drivers, and guest operating systems. Benefits of NVIDIA hardware-accelerated graphics to virtualized solutions, Instant Clone(Not a clear Idea of it yet.)

Discussing on Compute people criticise saying, no one build VM with 128 vCPU and 4 TB of RAM, but VMware is trying to showcase  that now we can go back to our client with a confidence that in VMware we can easily manage Jumbo VM’s

Storage: VVOLs the most discussed topic in VMware now. VMware has demonstrated significant enhancement in storage performance with introduction of VVOLs where Virtual Volumes* enables exact combinations of data services (such as clones and snapshots) to be instantiated more efficiently on a per VM basis. VVOL is going to talk with external storage arrays to become VM-aware. Storage Policy-Based Management.

Network: Network IO Control, Multicast Snooping  and Multiple TCP/IP stack for vMotion are the area of added element to existing VDS.  It seems for networking VMware has given full dedication to NSX.

Availability: The area of improvement which means to us most and VMware has definitely done league ahead improvements. Fault Tolerance with 4 vCPU support. Long Distance vMotion in other words vMotion across distributed switches and vCenter Servers and over distances of up to 100ms RTT.

Management: Items like Content Library, Cross-vCenter Clone and Migration and Enhanced User Interface are the big improvements or add-on to the Genx6.

VMware Data Protection 6

With the name change from VDR to VDP from 5.x to 6.0 VMware has done huge improvements in backup concepts. Though Veeam being the market leader for Virtual Machine backup.

In Genx6 release of VDP appliance is more robust and flexible. Talking of licensing first, all vSphere Data Protection Advanced functionality has been consolidated into vSphere Data Protection 6.0 and included with vSphere 6.0 Essentials Plus Kit and higher editions(which was sold separately before).

Application backup is the biggest advantage of the VDP. Exchange, Sharepoint and MS SQL backup can be done hassle free. These agents support SQL Server Failover and AlwaysOn Clusters and Exchange Database Availability Groups.

VDP 6.0 includes is replication of backup data between VDP 6.0 virtual appliances. This means If we take backup at site A and the backup can be replicated over WAN at site B. In case of Disaster it can be recovered easily though RPO will be list backup time.

Now backup can be restored in an isolated network for verifying the backup VM is good enough after restore. Later it can be deleted.

 VMware Virtual SAN 6.0

VMware has shows the path of SDDC with release of vSAN in vSphere 5.5. With the release of vSAN 6.0 VMware tried to expand the scalability and performance. For more detail on vSAN refer VSAN  blog from Duncan Epping .

New features include Virtual SAN All-Flash architecture. Scalability upto 64 host per cluster,  200 VMs per host,  6400 VM per cluster, Disk can be of 62 TB VMDKs. Performance has been boosted, hybrid IOPS are 40K per host which is double of vSAN 5.5, Flash IOPS are 90K per host  with is four time the vSAN 6.0. Virtual SAN File System which  improve the performance of Clone/Snapshot and support up to 32 snapshot per VM. Rack Awareness : this provide the high availability to track rack failures along with network and disk. Support for High Density Storage Systems with Direct-Attached JBOD . Support for hardware-based checksum and encryption
