VMware Horizon 6 Overview

image.png

VMware Horizon 6 was announced in April and began shipping in June while most of the world was preoccupied with the World Cup. The latest update to Horizon includes several major enhancements:

• Cloud Pod Architecture

• Application Catalog

• Remote Desktop Session (RDS) support

• Virtual SAN (VSAN)

• Automation

• vCenter Operations for View 6

• Horizon Mirage update

• VMware Safe Passage Program

The new release brings a more unified suite delivering more integration with infrastructure and cloud products and more simplicity for all devices. Along with the numerous updates across the Horizon suite, VMware has transitioned to a more traditional product licensing hierarchy.

Cloud Pod Architecture

One of the more intriguing features of the Horizon 6 suite is the Cloud Pod Architecture. With this feature, it is possible to link together multiple View pods in order to provide a single larger desktop brokering and management environment. An administrator manages each pod independently like a traditional View implementation. A View pod is a unit of organization determined by Horizon View’s scalability limits and consists of several objects:

• A set of View Connection Servers

• A database server (either Microsoft SQL or Oracle)

• Shared storage

• The vSphere and network infrastructure required for hosting desktop virtual machines

Using Cloud Pod Architecture, multiple pods can be joined together to form what is called a pod federation. This pod federation is able to span multiple datacenters and sites

—simplifying the administration required to manage a large View environment. This architecture allows up to 20,000 desktops to be created to include up to four pods, two sites, and 20 View Connection Servers.

At this moment, there is no support for remote Windows applications hosted on Microsoft Remote Desktop Services (RDS) hosts nor is there support for the HTML access feature.

Application Catalog

VMware has enhanced its application catalog, now called Horizon Unified Workspace

—renamed from just Horizon Workspace. End users are now able to access all desktops and applications using the single unified workspace interface. This supports a single sign-on (SSO) experience, delivering virtual applications hosted locally on datacenter devices, Office 365, web applications, software as a service (SAAS) applications, Citrix XenApp published applications, and RDS hosted applications. Because of the Microsoft RDS support and the Horizon 6 Unified Workspace front-end, administrators can use VMware to publish applications to Windows, Android, Mac, and iOS endpoints without using ThinApp. This type of flexibility is very attractive to many customers.

VMware Horizon Unified Workspace, or VMware Horizon Workspace 2.0 (the latest version), does not use the Horizon Files feature any longer. This functionality has been relocated to the newly acquired AirWatch Secure Content Locker. The data-va files from VMware Horizon Workspace 1.x can be exported to any Enterprise File Synchronization and Sharing (EFSS) system, such as the previously mentioned AirWatch product. See

http://kb.vmware.com/kb/2080325 for more information.

Remote Desktop Services (RDS) Support

RDS, formally known as Terminal Services, is a Windows Server role that enables users to access virtual machine-based desktops, session-based desktops, or even datacenter applications. RDS desktops and RDS-hosted applications can be used with Horizon 6. However, this is only available with Windows Server 2008 or 2012.

To use RDS:

1. First, install the Horizon View agent on the Microsoft RDS server.

2. Create a desktop pool and choosing the RDS server from the list of options for the pool type.

There has always been support for Terminal Server within Horizon View. Since the change from Terminal Server to RDS, VMware has worked closely with Microsoft to build a protocol provider for RDS. Another wonderful benefit is that this facet provides a seamless way for Mac users to run remote Windows applications. The applications will be managed using Horizon Workspace and the desktops using Horizon View. Administrators that are already accustomed to using to managing RDS host-based applications or desktop remote solutions will already feel comfortable using the feature.

Virtual SAN (VSAN)

VMware announced Virtual SAN (VSAN) as a part of the vSphere 5.5 release in 2013 and has included it as a part of the Horizon 6 Advanced and Enterprise Editions.

For those unfamiliar with VSAN, it is a software-defined storage solution but it is unlike other products that are currently available; it is built directly into the hypervisor. VSAN is very simple to configure and manage, and is also flexible—you can add more disks to the ESXi hosts or add more ESXi hosts to the VSAN configure to scale. Virtual SAN combines solid-state drives (SSDs) and hard disk drives (HDDs). SSDs are used for read caching and write buffering whereas the HDDs are used for data storage. Another benefit is that there is policy-based management on a per-virtual-machine basis. Horizon 6 automatically deploys a set of virtual machine storage policies to vCenter for use with virtual desktops. These policies can be applied granularly at the virtual disk level.

This convergence of storage and computing resources allows more granular control of availability and performance than anything I have worked with before. By providing full integration with VSAN, VMware aims to place a smaller burden on enterprise storage infrastructures in order to make way for more cost-effective virtual desktop infrastructure (VDI) deployments.

vCenter Orchestrator (vCO) Plug-in and vCenter Automation Center (vCAC) Extensibility

The vCenter Orchestrator (vCO) plug-in for Horizon allows interaction between Horizon 6 and vCenter Orchestrator. There is a set of standard workflows that enable self-service requesting and approval, automation, and scalable administration; custom workflows may also be created.

vCenter Orchestrator powers the Horizon vCO plug-in. vCenter Orchestrator is an automation platform for development and processes that is used to manage the vCenter Server infrastructure and now Horizon (with View) objects and pools. The new plug-in provides automation between the Horizon products that the workflows interact with and the environment in which the workflows are executed. The vCO workflows can be used natively with vCenter Orchestrator, using the vSphere Web Client and even through the vCloud Automation Center (vCAC).

The interoperability between the Horizon Suite, vSphere, and vCloud products is getting better with every release. vCAC provides a self-service portal that is highly customizable, allowing customers to access the cloud-provisioning services where users can request services from a catalog. All the technical processes are automated and seamless to the users.

vCenter Operations for View

Another great example of the extensibility provided by Horizon 6 is vCenter Operations for View. Customers are now able to manage desktop and server environments with a single vCOPs deployment. The Horizon metrics are now represented as dashboards rather than having to set up a separate custom deployment like before. Administrators are able to change the number of widgets and metrics types that appear on the dashboard, as well as create custom dashboards.

There is more visibility for guest operating systems, application processes, and the resources consumed so that the administrator can troubleshoot and manage the performance of desktop guest operating systems in a more intelligent manner. vCOPs for View observes the entire infrastructure stack, ultimately building a correlation between the end-user experience and the observed performance metrics. It begins establishing dynamic thresholds for resource consumption after two weeks of running in the environment.

Furthering the integration between vCOPs and the Horizon Suite makes monitoring the environments easier and more accurate than ever before.

Horizon Mirage

Horizon Mirage is also being upgraded to version 5.0 as a part of the Horizon 6 announcement. One major update is that there is full support, which includes migration support, image management, and disaster-recovery support for Windows 8.1. Also announced was cross-migration support

—meaning that there is x32 and x64 compatibility, where the reference can be 32-bit and the target is 64-bit. The Mirage Gateway, introduced with version 4.4, is also being updated as a part of the new release. Mirage Gateway assists with the simplification of managing endpoints for users distributed across the wide area network (WAN). The new version requires fewer back-end resources to support the clients due to performance tuning and scaling of the Mirage Gateway product.

The View Transfer Server, and thus the Local Mode feature, is no longer a part of the Horizon 6 architecture. The “offline virtual desktop” functionality is, however, not completely off the table. Local Mode was replaced by the combination of using Horizon Mirage with a “type 2” hypervisor, such as VMware Workstation, VMware Player, or VMware Fusion.

VMware Safe Passage Program

In July, VMware announced a new program known as Safe Passage. This is initiative makes it easier for organizations to migrate their existing virtual desktop infrastructures, mobile device management (MDM), and application-delivery solutions to AirWatch by VMware and VMware Horizon. The initiative aims to persuade more companies to switch to Horizon 6 without having to endure major data-migration issues or significant cost.

The migration tools and services to ease the transition include:

• Horizon 6 Upgrade Kit

• Citrix XenApp to Horizon 6 Migration Service

• Citrix XenApp to Horizon 6 Migration Tool

As a bonus to the tool set, new users will also receive three years of support and subscription service for around the same cost as three years of their current solution and support program. VMware is also working with customers with MDM to migrate to AirWatch by VMware for their enterprise mobility management (EMM) solution

—and provides a similar migration (as listed above) for moving to the new platform.

Conclusion

With Horizon 6, VMware looks to be delivering on the promise that end-user computing (EUC) is one of its three strategic areas of focus. This release is quite the complementary solution for VMware’s existing portfolio. Horizon 6 gives users a more complete and extensive way to modify and manage their virtual desktop infrastructures while still lowering the total cost of ownership. The further integration of AirWatch into the Horizon Suite is something to look forward to for future releases. As for now, Horizon 6 is definitely a step in the right direction. Upgrade today!

Server sales have turned a corner, IDC says

server_illustration-11378526.jpg

Server sales have picked up after a long slow spell and are likely to stay buoyant well into 2015 and beyond, IDC said Tuesday.

The growth last quarter was modest — worldwide server revenue climbed just 2.5 percent from a year earlier — but server makers will welcome the news after five consecutive quarters of declines.

Server makers are benefitting from the start of a cyclical refresh cycle, as customers replace systems they deployed soon after the financial crisis, IDC said.

But there are other factors at work too, said IDC analyst Kuba Stolarski. Sales of x86 servers have been strong for some time, lifted by companies like Google and Facebook building out their massive infrastructures.

But at the higher end of the market, sales of pricey Unix and mainframe systems have been in decline for years, dragging down the server market as a whole. Now, those systems comprise a small enough share of the market that the x86 gains can shine though, Stolarski said.

What’s more, sales of a new type of midrange system — the converged infrastructure products sold by companies like Cisco Systems and VCE — have been increasing, also contributing to overall growth.

The upshot of those trends is that the server market eked out some growth in the April-June quarter. Worldwide factory revenue reached $12.6 billion, up from $12.3 billion last quarter.

Two upcoming developments mean the growth should continue and then accelerate next year, IDC said.

One is the release of servers based on Intel’s Grantley Xeon server platform, expected at its developer conference in San Francisco next month. A new Intel chip usually prompts a wave of server purchases.

Further out, Microsoft will end support next year for its widely used Windows Server 2003 OS, which will prompt more upgrades.

Anyone expecting a “Windows XP” moment for servers should beware, though. The transition will likely be slower, Stolarski said, and some customers will keep their existing hardware and upgrade the OS.

Hewlett-Packard kept its top position in the server market last quarter with 25.4 percent of revenue, up slightly from the year before.

Cisco was the biggest winner, expanding its revenue 35.4 percent. It still has a small share overall, at 4.4 percent, but IDC said it took joint fourth place with Oracle, whose sales increased slightly.

Among the losers last quarter were IBM, which is in the process of selling its x86 server business to Lenovo, and saw its sales drop 10 percent, and Dell, which is now a private company and saw sales decline 6.5 percent, according to IDC.

Microsoft jumps into NoSQL market with new Azure data store

AzureArchitecture2H640px.png

Jumping into the growing NoSQL market, Microsoft has debuted a simple data store through the Azure cloud hosting service.

The document database is well suited for organizations or startups that need a back-end database for storing data on a mobile or Web application, according to Vibhor Kapoor, Microsoft Azure product marketing manager, who introduced the service in a blog post Thursday.

The Azure DocumentDB service, now in preview, is the first NoSQL-styled document database from Microsoft. Azure also offers a number of other NoSQL databases from other vendors, including those from MongoDB, MongoLabs, Nodejitsu, Redis and RavenHQ.

In addition to providing basic document storage capabilities, the service also offers query processing and transaction semantics, two features usually found in relational database systems.

A number of NoSQL databases have sprung up over the past decade to address the need of storing and accessing large amounts of information very quickly, sometimes across multiple servers. Traditional SQL databases have been hard-pressed to scale to the sizes typically required for such work.

Microsoft also announced a number of other initiatives around its cloud service. It is offering the Bing search as a service that can be embedded within third-party applications. Apache HBase database software is now available within Azure’s Hadoop service. And Azure now offers over 300 virtual machine images pre-configured for a variety of tasks.

10 questions to ask when interviewing candidates for IT positions

Hero

Hiring IT staff is a difficult task, and too many IT leaders leave it solely in the hands of HR. Here are 10 questions you can ask potential IT hires — and an explanation of what each question can tell you about the candidate.

1: What are two or three major trends affecting the IT industry and how do you see them affecting the profession?

This is a big picture question, and the trends the candidate identifies are less important than the candidate’s ability to identify broad industry trends and articulate their impact. Essentially, you’re assessing whether candidates can think broadly about what’s happening in the industry and whether they actively monitor changes in the industry.

2: Tell me about a time you were asked to perform a task or project you didn’t understand

This question is more appropriate for staff than leaders, but in both cases will help tease out how candidates act in unclear circumstances. Can they provide examples of how they asked for clarity or came up with a plan to identify missing information? Or do they sound like they spin their wheels until someone else intervenes?

3: Tell me about a time you were asked to do something you’ve never done before (new technology, different type of project, new industry, etc.)

This is similar to the previous question, but the crux of this one is whether candidates are self-starters who can rapidly adapt to a changing environment. If they don’t have experience dealing with change — or they struggle to answer — that should be a warning sign.

4: Do you get bored easily?

This is an interesting question, since the two extremes of possible answers may be “correct” depending on the role you’re trying to fill. If you’re looking to fill a strategy- or project-related role, where the candidate will be bouncing from project to project on a weekly or monthly basis, you want someone who is easily bored and constantly looking for new challenges. If you need a competent manager or staff member to run a steady-state process and sweat the details, you obviously want a very different candidate.

5: What types of activities would you expect and prefer this role to entail?

This is a subtle way of determining whether candidates understand the role they’re applying for and whether their expectations match yours. If you’re serious about a candidate and your expectations don’t match, this will be a critical point of discussion as you move forward in the hiring process.

6: Where do you want your career to go and what skills would you like to learn and develop as our employee?

This is similar to the above question, but with a more long-term outlook. If a candidate expects development opportunities you can’t provide, you’ll need to reconcile that concern or end up with an unhappy employee. This question can also help determine whether the candidate has leadership aspirations and a plan to achieve them.

7: If you could make two or three changes at your former place of employment, what would they be?

This seemingly straightforward question accomplishes a number of things. First of all, it’s a good check of the ability to keep confidential information secret, as well as an indication of whether a candidate will badmouth a former employer. Second, this question tests the candidate’s ability to think broadly and strategically. Like question 1, the content of the answer is less important than the thought process that goes into the answer — unless the best the candidate can come up with is something banal like, “My last employer should have bought better coffee.”

8: Ask a case question

Case study questions may seem like a complicated process left to the business schools and consulting houses, but they can be as simple as summarizing a complex situation you faced and seeing how the candidate responds. Provide an overview of a recent situation you or your company faced and test the candidate’s ability to identify and articulate a solution on the fly. Perhaps more important than the solution the candidates develop are the questions they ask. They won’t have critical details or background on the problem, so observing how they gather information and begin to break down the problem is the most interesting aspect of case-style questions.

9: Ask a “tough employee” question

For candidates who will be managing others, present a difficult employee situation, ideally based on a challenge you’ve faced in the past. See if candidates ask relevant questions about the situation and observe their thought process in determining how to resolve the situation.

10: Ask about a hobby or interest (if it’s mentioned on their résumé)

If candidates mention a hobby or interest on their résumé, ask them about it. Rather than making small talk, you want to see if candidates are well-rounded individuals and get some feeling for their personality. While “likability” should not be your sole factor for determining employment, many roles require some amount of sales ability, and certainly presentation and speaking skills. Hobbies can also tell you about a candidate’s risk tolerance, willingness to experience new things, and general outlook on life. Even if the specific hobby in question is an activity you don’t enjoy, use the question to check the candidate’s ability to articulate and convey passion.

SanDisk’s Ultra II SSD offers lowest prices with capacity up to 960GB

Computerworld – SanDisk today announced its latest consumer-class solid-state drive (SSD), the SanDisk Ultra II, which comes with the company’s lowest price point to date for a flash drive.

While SanDisk’s media presentations and statement on the drive focus on the SSD’s improved performance and a new dashboard tool for monitoring performance and SSD health, what stands out the most is the price point: as little as 44 cents per gigabyte of capacity.Ultra II

The Ultra II follows the Ultra Plus, but the Ultra II is SanDisk’s first triple-level cell (TLC) NAND flash-based client SSD aimed at delivering high performance and reliability to the mainstream consumer. Triple-level cell flash simply means the three bits of data is stored per memory cell versus two bits with multi-level cell (MLC) NAND flash.

Because TLC flash stores data more densely than MLC, it can achieve a lower price point.

The Ultra II is the follow-up to the SanDisk Ultra Plus SSD released early last year. At the time of its announcement, the Ultra Plus SSD came in capacities from 64GB ($75 retail price) to 256GB ($210 retail price).

The new Ultra II SSD comes in 120GB ($80), 240GB ($115), 480GB ($220), and 960GB ($430).

While the price point on the Ultra II SSD dropped dramatically, performance increased. The new SSD is up to 55MBps faster than its predecessor for writes and 20MBps for reads.

Read/WritesSanDisk Ultra II’s read/write performance (Image: SanDisk).

The SanDisk Ultra II has a maximum sequential read/write speed of 550MBps and 500MBps, respectively. The SSD’s random read/write performance tops out at 99,000 I/Os per second (IOPS) and 83,000 IOPS, respectively.

By comparison, Samsung’s TLC consumer SSD, the 840 EVO, retails for as little as $469 for a 1TB model. Samsung’s 840 EVO SSD read/write performance tops out at 540MB/s and 520MB/s, respectively.

As with other consumer-grade SSDs, SanDisk’s new drive is designed and being marketed to deliver a cost-effective and upgrade for desktop and laptop users who want to increase performance, battery life and power efficiency.

For example, SanDisk claims the Ultra II SSD can increase laptop battery life by 15% over a system that uses a hard disk drive.

Like SanDisk’s higher-end SSDs, the new SanDisk Ultra II comes with SanDisk’s nCache Pro firmware, a write cache technology that reduces SSD wear by assembling data to be stored in the most efficient manner prior to being written to the NAND flash.

The SSD also comes with an enhanced SSD Dashboard that offers users visibility into the drive’s performance, security and available firmware updates.

“We live in an era where we expect to have information at our fingertips anytime, anywhere, with technology that keeps us connected to both our personal and work lives on devices that won’t fail,” Dinesh Bahal, vice president of retail product marketing at SanDisk, said in a statement. “The new SanDisk Ultra II SSD, together with the improved SSD Dashboard, provides consumers with an easy, affordable way to ensure that their PC can keep pace with their increasingly connected, information-driven lifestyle.”
