Storage Optimization with VMware Horizon View

without comments

Great article on storage optimization technologies for VMware from VMware Product Management. Learn more about VMware View Replica Tiering, View Storage Acceleration, View Composer API  for Array Integration (VCAI) and space efficient virtual disks.

Properly designing and sizing storage is key to successfully deploying virtual desktops. Transitioning from pilot to production is completely dependent on getting both the storage design and sizing right. If you get this wrong- you will negatively affect user experience, application responsiveness and your cost per desktop.

So how do you get it right?

Well ultimately you will need to ensure that your VDI environment is designed to support adequate capacity and performance. Translating a physical laptop/desktop environment to a desktop VM typically requires about 40GB of storage capacity and 15 to 200 IOPS . In addition, the IO pattern is made up of steady state events during which it is dominated by small block random writes and highly correlated peak events which can be dominated by either reads or writes. These shifts complicate storage sizing and design for VDI.

Riverbed to optimize PCoIP network traffic

with one comment

During VMworld in Las Vegas, Teradici announced a new partner program to enable network optimization for PCoIP traffic. The first company to joint the Network Solution partner program is Riverbed. Please see the press announcement attached.

VMworld Las Vegas — August 30, 2011 —Today at VMworld® 2011, Teradici Corporation, the developer of the innovative PC-over-IP® (PCoIP®) protocol that enables a true PC experience for desktop virtualization, today announced the Teradici Network Solutions Partner Program. First to join the program will be charter program partner Riverbed Technology (NASDAQ: RVBD), the IT performance company and market leader in wide area network (WAN) optimization. Teradici and Riverbed® will engage in a strategic partnership to ensure the high performance of Virtual Desktop Infrastructure for VMware View™ environments.

The Teradici Network Solutions Partner Program has been developed to help build technical partnerships with network OEMs to enable the integration and optimization of PCoIP® technology. The program allows network OEMs to access the PCoIP protocol and protocol interfaces, allowing for network optimization of UDP-based PCoIP traffic.


“We see our future collaboration with Teradici and the Network Solutions Partner Program as a great way to show our continued commitment to accelerating Virtual Desktop Infrastructure,” said Venugopal Pai, vice president of global alliances at Riverbed. “We’re looking forward to our partnership with Teradici since they are the developer of the PCoIP protocol, offering uncompromised VMware View desktop experiences for all user types.”


“We’re thrilled to be announcing our Network Solutions Partner Program and the planned partnership with industry leader Riverbed Technology,” said Trent Punnett, vice president of marketing, product management and systems engineering, Teradici. “The goal of the program is to provide members with access to PCoIP technology and a roadmap of features, products and platform offerings, thus allowing Network OEMs to differentiate and build value added into PCoIP® based VDI optimization and management solutions.”


Partner Program members receive numerous benefits including: access to Teradici PCoIP technology, network solutions and support; advanced input into PCoIP solution architecture and features; reserved access to alpha, beta, and RC releases; and access to documentation and technical guidance from the Teradici engineering team. Other program elements include “PCoIP Optimized” certification for partner solutions.


“The strategic partnership being developed by Teradici and Riverbed is a strong example of the industry commitment to solving IT pain points and optimizing networks,” said Vittorio Viarengo, vice president, End-User Computing, VMware. “We are committed to delivering industry-leading, high-performance VDI for VMware View™ environments to empower a more agile, productive and connected enterprise, and this alliance will help us to achieve this goal.”

About PCoIP Technology

Teradici’s PCoIP protocol is an innovative remote display technology that allows the user’s desktop operating system, applications, and data to reside in the datacenter, eliminating the need for traditional desktop workstations, PCs and thin clients, and delivers an uncompromised user experience to each person, anywhere, over any network and to any type of device without incurring the security risks associated with having data reside in remote PCs, laptops, or tablets. PCoIP technology provides high resolution, full frame rate 3D graphics and high-definition media, with full USB peripheral interoperability, locally over LAN or remotely over high-latency WAN networks. It compresses, encrypts and encodes the entire computing experience at the datacenter and transmits it ‘pixels only’ across a standard IP network to secure, stateless PCoIP zero clients, thin clients, and mobile devices.


The PCoIP protocol is implemented in several software configurations, including VMware View™, the industry leading desktop virtualization platform as well as in silicon for hardware accelerated performance and enhanced security. A growing ecosystem of over 30 third-party vendors provide a wide variety of PCoIP products including server plug-in cards, rack and tower workstations, blade PCs, zero clients, integrated monitors, and IP phones with PCoIP capability.


About Teradici

Teradici Corporation has developed PCoIP® (PC-over-IP®) protocol, a unique remote display technology which makes network delivered computing a viable corporate computing reality. Founded in 2004 and headquartered in Burnaby, BC, Canada, Teradici for the first time enables an exceptional end user experience for datacenter-based computing. Through a combination of unique graphics algorithms, flexible software solutions and high-performance silicon processing, and workstation/server add-in cards, the company is changing how personal computers are used, deployed and managed.

Optimizing performance for VPS and low RAM

with one comment

Running out of memory will prevent the Linux system from running ZCS because it can’t create the needed Java virtual machine and also start essential processes like the MTA. During the installation I came to several situations where I ran out of memory but in the end I could install the software but not start all services. I needed some optimization here. After some searching on the web I found tips which helped me.
