Hybrid Clouds, Mobility Management And SDN Key For VMware’s Q2 Results

Virtualization and Cloud Computing VMware giant will announce its Q2 2014 earnings on 22 July, the company reported an increase over the previous year (yoy) in its two sources of income – Revenue from product licenses (15%) and services income (14%) – in the previous quarter.Software license gross margins of the company have in recent years improved from 87.7% in 2009 to over 90% in 2013, continuing the trend, gross margins for software licenses rose to over 91% for the first quarter of 2014 – in line with the company’s expectations. VMware expects its margins maintained at a level nearly Q1 forthe full year.

Mentioned VMware management that three main focus of the company are data centers, software-defined, the hybrid vCloud suite and end-user computing. Software-Defined Networking storage and software defined both are integral to the vision of VMware SDDC articulated. The company saw a positive response from customers, both NSX VMware, the virtualization platform of the network and the virtual network recently SAN (VSAN) defined in the first quarter storage platform software. Increasing competition from rivals virtualization and cloud providers Amazon, Cisco, Microsoft and Citrix central concern remain for the company in the coming quarters. We have an estimated price of $ 100 for the shares of VMware, which is slightly higher than the current market price.

High Expectations From Network Virtualization

VMware has dominated the market for server virtualization in recent years, with a market share of 55-60% in this segment. However, competitors such as Microsoft’s product offering and Citrix have to compete with VMware developed and gained market share by offering competitive prices in the last years with him. Since server virtualization is a mature market, VMware has shifted its focus to develop technologies such as network virtualization and software-defined memory in the new market. VMware introduced the NSX a software-defined networking platform customized end 2013, to settle in the fast-growing segment. The company said there is a breakthrough in the last quarter by signing agreements with major customers, including a number of large companies in the financial, banking and telecommunications. SDN Management expects to follow a similar company as server virtualization path in 2009.

Judging by this 2014 estimate should be a very productive year for the company, as SDN has begun to gain traction among buyers.In June, VMware announced that it has started selling licenses NSX through channel partners. VMware already has more than 10 partners on board, and look for the company to add more in Q3. The company plans to launch a channel-NSX-competition program at the VMworld conference in August to explore other channel partners. The enhanced security feature in the NSX could be more popular in the long term, the company expects the most significant contributions of network virtualization in the coming quarters (see VMware and Cisco to fight In The Sand SDN). A central concern here is VMware Cisco approach open to the SDN architecture that could be cut into the market when it gains popularity VMware code.

Other Areas Of Growth

VMware introduced its virtual SAN storage defined by software that is fully compatible with vSphere virtualization platform, at the end of the previous quarter. This converged infrastructure targets both large companies and small and medium enterprises. The company had a virtual SAN licensed for sale only two weeks in Q1 and saw a strong reaction by the product. Management mentioned that the company has already signed an important agreement for a Q2 dealer in the same quarter.

VMware vCloud Suite was largely responsible for driving sales in the second half of 2013. The company recorded strong growth (nearly 18%) in service revenue in 2013. Trend continued in the first quarter with a company services income increased 14% over the same quarter last year. VMware Service Department is likely to continue to take advantage of your offer as a service hybrid cloud hybrid vCloud gaining popularity among buyers of the crop. The company has expanded to the U.S., in Asia, with Japan in the third country and the United Kingdom, where VMware deploy its hybrid solution. The company also signed an agreement with China Telecom, hybrid cloud service, which will be ready next year to build.

vSphere 6, Virtual Volumes Beta Testing Now Open

VMware has released another public beta of vSphere 6.0, the next major update of its hypervisor technology. As part of this second public beta, the company is also beta testing virtual volumes, an approach to managing the virtual memory.

vsphere-6.0

Information about VMware vSphere Beta Community landing page is published to the vSphere 6.0 private beta goes public to accelerate large-scale testing. No details on the expected functions offered there, and beta testers advises not to use these beta products before downloading to the fact the discussion. Bloggers and takes a stab at vExpert what features to expect, though written in this blog in April. Some guesses of interest:

  • Storage vMotion and basic storage API integration
  • Lots of cloud integration capabilities
  • Snapshot and clone support for Microsoft Exchange and SQL Server
  • Improved clustering and high availability
  • Improved mobility features
  • Improved vOps

Anyone can go to the landing page for the beta.Virtual volumes, even in public beta under the same program, is a new method for the management and storage provisioning, which takes the place of the traditional LUN that can be used. VMware has more on VVOLs here.

In very simple terms, today, LUN layout or export / shares and then use them to data warehouses where we store create the virtual machines. You end up with hosts that have multiple LUN or multiple exports/shares. While NFS makes it a little better, from the perspective of the presentation is still not good enough.

With VVols, the storage array is essentially represents a single LUN or export/shares of the host and allows the virtual band provisioning on the VM level to be successful. Compliment that have greatly simplified with a motor and good QoS rules, and you have a very elegant way to handle storage.

There is a simple explanation of what VVOLs were at the time, and, and, of course, has changed since then. (Also considered a version of VMware VVOLs back at VMworld 2011.) We will be more details in the coming weeks.On a side note, Blogs VMware Global Partner organization’s senior vice David O’Callaghan, the Entperise AirWatch mobility management platform is available worldwide by subscription cloud VMware partner programs. VMware acquires AirWatch in January.

Sample Question : 25

VMware Question:

A virtual machine requires a 4TB disk for application data. The storage administrator has already created and presented a 4TB LUN to an ESXi 5.x host. The host is currently configured with a single 500GB VMFS5 datastore.What is the next step the vSphere administrator must use to provision the data disk?

A. Create a virtual compatibility mode RDM mapping to the 4TB LUN.

B. Create a physical compatibility mode RDM mapping to the 4TB LUN.

C. Expand the existing VMFS volume to 4TB. Create a physical compatibility mode RDM mapping to the 4TB LUN.

D. Expand the existing VMFS volume to 4TB. Create a virtual compatibility mode RDM mapping to the 4TB LUN.

Answer. B

VSANs Choking on VMware’s Recommended Components

VMware has changed the recommended networks of virtual storage area for some components can be turned recipe is not for the change notification job.Virtzilla ‘s is, it’s done, since some offer once recommended IO controller low range very low IO by put.So low, in fact, that the probability that the driver to complete queue is high. If the IO controller queue is full, IO operations timeout, and virtual machines stop responding.

VMware seems to have known about these problems for a while. When Marcus Van Den Berg blog up2v notes, posted a VMware support VSAN user response to your problems with a response from Dell H310 controller Reddit.That posted here almost a month ago, says Although this driver has been certified and is our hardware compatibility list means that your cluster using VSAN could face both a recreation activity and running production workloads.

The e-mail VMware continues, in order to avoid such problems in the future, we will re-evaluate our hardware compatibility list. Our intention is for the restoration hardware / sync scenarios. VMware 19 drivers from the list, from 1 July no longer supported in the support systems that meets a minimum threshold of order and VSAN.The explanation for their withdrawal follows:

As part of ongoing efforts to test and certify VMware virtual hardware support SAN, VMware has decided to remove the driver from the virtual SAN Compatibility List. While fully functional, these controls offer too low to support IO performance to the performance requirements of most VMware environments. Presented by the low queue depth of these drivers, you may even take a moderate pace in IO IO timeout operations; especially in the hard disk drive rebuild operations.

In this case, the driver may not be able to cause prolonged recovery and slow responsiveness of the application of both a type of sleeve and rerun the IO virtual machine. In order to avoid problems such as those described above, these drivers the hardware compatibility list for VMware will be deleted.

Could this message be translated as Ooops? We have a few things on the list that should not have and / or should have been thoroughly tested? Disseminate, especially if you contact to take VMware offer customer service, if you bought the kit banished from their lists us in the comments.
