What's new in SQL Server 2012 for philly code camp 2012.1Mark Kromer
A high-level run through the SQL Server roadmap focused on the new technologies and features of SQL Server 2012. Mark Kromer presented this deck to the Philly .NET Code Camp in at Penn State Abington on May 12, 2012.
The purpose of this paper is to set appropriate expectations for customers with regard to disaster recovery and workload migration options when using IBM NAS solutions with VMware vCenter Site Recovery Manager host-based replication. To know more about VMware, visit http://ibm.co/SOUdWO.
Purchasing chassis with large numbers of HDDs is one way to configure your infrastructure, but such a solution can provide less than optimal performance, take up a large amount of prime data center space, and increase power and cooling costs. Configuring your servers with SSDs, on the other hand, can dramatically improve performance while simultaneously reducing the overall power consumption of your data center.
In our tests, replacing 24 HDDs in an external chassis with only six internal Kingston SSDs boosted total database performance by as much as 91.8 percent. Not only did the server with Kingston SSDs outperform the HDD solution, it also consumed 32.5 percent less power while active and 51.0 percent less power when idle. Such dramatic performance increases and reduction in power consumption can make Kingston SSDs a compelling choice for the database servers in your data center.
Automated storage tiering uses SSDs as a high-performance tier and HDDs as slower tiers. Intelligent algorithms identify "hot" data and move it to SSDs for fast access, then return it to HDDs when no longer hot. This approach uses fewer SSDs more efficiently than manual tiering. However, it remains difficult to determine which applications will benefit, as there are no tools to identify active data set sizes or predict performance gains on different storage media. Workloads with identifiable access hotspots are better candidates for tiering than those without.

Investing in GenAI: Cost‑benefit analysis of Dell on‑premises deployments vs....Principled Technologies
Conclusion
Diving into the world of GenAI has the potential to yield a great many benefits for your organization, but it first requires consideration for how best to implement those GenAI workloads. Whether your AI goals are to create a chatbot for online visitors, generate marketing materials, aid troubleshooting, or something else, implementing an AI solution requires careful planning and decision-making. A major decision is whether to host GenAI in the cloud or keep your data on premises. Traditional on-premises solutions can provide superior security and control, a substantial concern when dealing with large amounts of potentially sensitive data. But will supporting a GenAI solution on site be a drain on an organization’s IT budget?
In our research, we found that the value proposition is just the opposite: Hosting GenAI workloads on premises, either in a traditional Dell solution or using a managed Dell APEX pay-per-use solution, could significantly lower your GenAI costs over 3 years compared to hosting these workloads in the cloud. In fact, we found that a comparable AWS SageMaker solution would cost up to 3.8 times as much and an Azure ML solution would cost up to 3.6 times as much as GenAI on a Dell APEX pay-per-use solution. These results show that organizations looking to implement GenAI and reap the business benefits to come can find many advantages in an on-premises Dell solution, whether they opt to purchase and manage it themselves or choose a subscription-based Dell APEX pay-per-use solution. Choosing an on-premises Dell solution could save your organization significantly over hosting GenAI in the cloud, while giving you control over the security and privacy of your data as well as any updates and changes to the environment, and while ensuring your environment is managed consistently.

In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.

Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

VDI performance comparison: Samsung solid-state drives vs. SAS drives in a Dell PowerEdge R720
1. VDI PERFORMANCE COMPARISON: SAMSUNG SOLID-STATE DRIVES VS.
SAS DRIVES IN A DELL POWEREDGE R720
Today’s servers are more powerful than ever and are ideally suited for
your virtual desktop infrastructure (VDI). They offer the latest in processing
power, memory speed, and storage technologies. The storage technologies you
select, in particular, can have a profound effect on the number of users each
server can support. You can use standard SAS drives in your servers or you can
upgrade—for only a modest additional investment—in Samsung solid-state
drives (SSDs).
In the Principled Technologies (PT) labs, we tested a Dell PowerEdge R720
server configured with both SAS hard drives and Samsung SSDs to quantify the
advantage SSDs can deliver. We found that this server configured with SAS drives
could support 82 virtual desktop users, while configured with Samsung SSDs it
supported 160 virtual desktop users—95 percent more desktop users.
FEBRUARY 2013
A PRINCIPLED TECHNOLOGIES TEST REPORT
Commissioned by Dell, Inc.
2. It is essential that your virtual desktop infrastructure can deliver the
performance your employees require today and have room to grow as your business
expands. Upgrading to SSDs in your Dell PowerEdge R720 server is an extremely cost-
effective choice—you can nearly double the number of users you can support.
We tested a single Dell PowerEdge R720 server two ways—with SAS drives and
with Samsung SSDs. The server was otherwise identical—it was preconfigured with
VMware vSphere 5.1. We installed and configured VMware View 5.1 to use a VMware
vCenter and VMware Composer Server. We created two automated, floating, linked
clone pools. We configured the pools to use 1 GB of host cache. The SSD pool had 160
desktops and the SAS pool had 83 desktops. We chose 83 desktops for SAS because it
was the smallest number of desktops needed to cause a VSImax in testing; VSImax
indicates user responsiveness is no longer acceptable. We used the Login VSI Medium
workload to generate a reproducible, real-world test case that simulated the execution
of various applications including Microsoft® Internet Explorer®, Adobe® Flash® video,
and Microsoft Office applications. Using Login VSI, we could determine how many
virtual desktop users each solution could support.
We configured Login VSI to run a Medium workload against a pool of virtual
desktops and set up the test to incrementally log in users every 6 seconds. Login VSI
measures the total response time of all the applications from each session and
calculates the VSI Index by taking the average response times and dropping the highest
and lowest 2 percent. The average response time of the first 15 sessions determines a
baseline; the VSImax is baseline x 125% + 3000ms. As more sessions begin to consume
system resources, response time degrades and the VSI index increases until it is above
the VSImax. When this condition is met, the benchmark records a Login VSImax, which is
the maximum number of sessions that platform could support.
SOLID-STATE DRIVES SUPPORTED NEARLY TWICE AS MANY USERS
In our tests, we found that the Dell PowerEdge R720 with Samsung SSDs was
able to host 160 concurrent sessions while retaining a satisfactory user experience, 95
percent more users than the same server with SAS drives, which could host only 82
sessions. For an additional hardware investment of only 6 percent (see Appendix C), the
Dell R720 with Samsung SSDs can support nearly twice the users.
Figure 1 shows the Login VSI response times, in milliseconds, for the two types
of storage. SSD testing did not reach VSImax. VSImax represents the maximum user
capacity at which performance did not degrade; therefore, not reaching VSImax is a
positive indicator that response time remained satisfactory. The SAS configuration did
reach VSImax, indicating the responsiveness for the 83-session test was considerably
degraded.

About Login VSI 3.6
Login Virtual Session Indexer (Login VSI) 3.6 is a tool that helps assess the virtual
desktop performance, capacity, and scalability of a server.
The newest version of Login VSI, Login VSI 3.6, includes client side performance
testing that test character response, large text response, mouse-click feedback, and
image quality and loading times on clients to ensure good end-user performance. In our
tests, we did not use the client-side testing portion of Login VSI, but instead used the
tool to determine how many virtual desktops the appliance could support. For more
information about Login VSI 3.6, see http://www.loginvsi.com/product-overview.
CONCLUSION
Choosing Samsung SSDs can dramatically boost the user count your VDI server
can support because of their ability to deliver low latency I/O. In our testing, simply
replacing standard SAS drives in a Dell PowerEdge R720 with Samsung SSDs improved
overall response times making it possible to nearly double the number of VMware View
5.1 virtual desktops—increasing this number from 82 to 160. This makes Samsung SSDs
an excellent choice for your virtual desktop infrastructure.
