The Dell PowerEdge Express Flash PCIe SSD is an enterprise class high performance storage device designed for applications that require low latency and high IOs Per Second (IOPs) operation. It is built with SLC NAND flash and can be used as an internal storage of Dell PowerEdge servers. This not only removes the performance bottleneck posted by the mechanical parts of conventional HDDs, also improves the storage IO performance by eliminating the latency and performance bottleneck between the server and the external storage. OLTP database workloads which require very low storage IO latency with many small random read/write IO operations are the ideal cases to use Dell Express Flash PCIe SSDs to improve the performance. To understand how PCIe SSDs improve OLTP database performance, several performance studies have been conducted on a single node Oracle 11g R2 database as well as a two node 11gR2 Oracle Real Application clusters (RAC) database running on Dell PowerEdge R720 servers with Oracle Linux 6.2 (Redhat Compatible Kernel) platform.
The published whitepaper explores the following three use cases of using PCIe SSDs to optimize Oracle database:1) Use PCIe SSDs as the primary database storage2) Use PCIe SSDs as a part of tiered storage combining with conventional hard disk storage3) Use PCIe SSDs as an extension of database cache with the Oracle database smart flash cache feature.
For more details on the different configurations, use cases and their comparative performance results please refer to the technical whitepaper posted at the following link:

Storage Maximizer (SMAX to you and me!) is a product that we know we will want to add to and enhance a lot over the coming years and that progress continues with our 2.1 release. Too busy to even read the rest of this entry, then download right now at http://www.quest.com/storage-maximizer-for-sharepoint/
You probably won't notice much in the UI, but that is due to the fact that SMAX does most of its activities under the cover, keeping a watchful eye on all the storage related to your SharePoint farm.
First off we made sure this product can perform. When we say scale up, we mean it! 2 Million plus objects were tested to the (S)Max with constant rule changes and options being applied. Blobs were externalized, reverted, externalized again! And not a single bit dropped. Some of this has been validated out in the field but good to have a testing lab that can dish it out, and SMAX can take it.
If you have used SMAX already, you may have noticed its simple with a capital S. In 2.1 we made sure nothing can slip you up by adding more to the pre install checks.
A 1.1 customer? We got you covered with the 1.1-2x upgrade tool. Low impact with no data reversion just click and go as long as you are keeping to EBS!
And finally, we have noticed that some of you have duplicate Site IDs. This shouldn't happen but it does, and it means that we struggle to determine where the file should go. We handle this more elegantly now so no worries as they say.
As a bonus we also support maintaining configuration between installs (in case you have to install and reinstall the app) and we support service pack updates too!
As always SMAX is free to use for 30 days while you get a feel for it! Download today at http://www.quest.com/storage-maximizer-for-sharepoint/
Look for more exciting releases of SMAX soon!

With the announcement of the Windows Server 2012 Release Candidate, we explored some of the changes on the server side and looked at how to launch some of the common administrative tasks within the new Windows Metro style user interface. We’ll provide a few tips to help you quickly navigate to the management task that you’re looking for.
First, a look at the current release. With Windows Server 2008 R2, it’s common to left-click the Start button to bring up the Start menu to select Administrative Tools, Control Panel or maybe use the search option to get to the management window of your choice to perform some particular task on your server.
With Windows Server 2012 Release Candidate, by hovering the mouse over the lower left corner of the screen a Start screen thumbnail will appear; you can right-click on the Start screen to bring up a context menu of administrative options. This new menu provides you with a toolbox of the most commonly used management functions to quickly get to your task at hand. For my testing, the addition of the Computer Management and Device Manager options have been very helpful in everyday work. Of course, you still have the old faithful Run dialog box which is the portal to any tool if you know the tool’s run command. This new menu gives you a direct launch point for the majority of the tools you’re looking for when managing your servers.
A side-by-side comparison of Windows Server 2008 R2 (left) and Windows Server 2012 RC (right) Start options.
When using remote management cards like the iDRAC7 on 12th Generation Dell servers, there is a built-in macro (Ctrl-Esc) provided that can be used to quickly open the Start screen on Windows Server 2012 Release Candidate.
After selecting the Ctrl-Esc macro from the iDRAC menu the Start screen opens:
These tips can help save you time when you need to quickly get to a particular tool or application for everyday IT operations. In addition to the above, the new Server Manager has a large number of administrative options available for local or multi-machine management.
For additional helpful resources, check out the Windows Server blogs.
Because Windows Server 2012 RC is a pre-release product, features are subject to change. Dell does not provide any support for this pre-release software and it is not recommended for use in a production environment. Feel free to check out the new features of the RC release on your test servers and let us know what you think. Stay tuned for more blogs from the Dell OS Engineering team.

Migrating Oracle databases presents many unique challenges for IT administrators; such as the complexity, data integrity requirements, and 24x7 availability requirements of critical database applications. To address these challenges, Dell offers a near zero downtime migration strategy in this whitepaper, which can help customers move Oracle databases into a new infrastructure with near zero downtime impact. This methodology has been proven to be reliable and repeatable with the adoption by Dell IT for a large scale Oracle database migration project. This methodology brings out the best of Dell Compellent storage features like thin provisioning and a well tested reference architecture using the latest generation Dell PowerEdge servers.
The migration methodology provided in the whitepaper is developed based on the reference configuration shown below.
The Oracle Real Application Cluster (RAC) database is migrated from the source system to the target system. The target Oracle database system consists of not only the latest hardware including the Dell PowerEdge 12th Generation servers, Dell Compellent storage systems, and SAN switches, but also newer operating system releases on the database servers.
Complete details on the migration methodology can be found in the Oracle Database Migration to Dell PowerEdge 12th Generation Servers and Dell Compellent Storage Systems whitepaper.

Dell Inc. announced the PowerEdge Express Flash PCIe-SSD devices a in May that corresponded to the launch of the Dell 12th Generation PowerEdge Servers – Wave 2. Dell adopted industry standards for form-factor and connector (can’t wait for the adoption of NVMExpress). Dell is an active participant in development of these standards. The launch of the PowerEdge PCIe Express Flash SSD’s is very exciting, but looking at the spec sheet one cannot miss the lack of support for VMware ESXi under the supported operating systems. Well, folks who want to experiment and evaluate this exciting new product in a VMware environment don’t have to just wait. Dell has partnered with Micron to deliver this product. The recently released device driver for the Micron PCI Express RealSSD product ‘seems’ to work with Dell PowerEdge Express Flash PCIe-SSDs. You can click here to download the driver from VMware’s site to enable Dell’s PCIe SSD under ESXi environment. There is also a VMware Knowledge Base article posted that talks about configuring these SSD devices.
Disclaimer: Please note that the Dell engineering teams have not completed validation of this driver on the PowerEdge PCIe Express Flash SSD devices and that using this device in a VMware ESXi configuration is not a supported configuration by Dell. This means, please use this only for prototyping your setups and not in your ESXi production environment as you will be on your own for any support issues.

The PCIe SSD industry is seeing an iconic increase in traffic (pun intended) with up to 1000x improvement in IOPS over traditional HDD. However, the market is plush with closed standards and proprietary driver based PCIe SSD based solutions.
Dell pioneered by first architecting open standards around the form factor and then developing open solutions around it by working with Linux Community to deliver an open-source driver for its Linux Customers. As a result, Red Hat Enterprise Linux 6.3 includes mtip32xx, the driver which adds support for Micron RealSSD P320h PCIe SSD drives which constitutes the Dell Express Flash PCIe SSD solution.
Dell engineers worked very closely with Micron and Red Hat engineers in testing, fixing and porting the driver towards delivering an open-ource solution that works out of the box on Red Hat Enterprise Linux 6.3 for Dell 12th Generation Servers with Express Flash technology. We continue to work with the community to make the native driver more feature ready while we support a more feature-rich open-source driver via Dell support that supports customers running Red Hat Enterprise Linux 6.2 and above.
