About this book
This IBM® Redbooks® publication introduces the IBM Storwize® V7000 Unified Disk System, a virtualized storage system that consolidates block and file workloads into a single storage system. Advantages include simplicity of management, reduced cost, highly scalable capacity, performance, and high availability. It also offers improved efficiency and flexibility through built-in solid-state drive optimization, thin provisioning, IBM Real-time CompressionTM, and nondisruptive migration of data from existing storage. The system can virtualize and reuse existing disk systems, which offers a greater potential return on investment.We suggest that you familiarize yourself with the following Redbooks publications to get the most from this book: Implementing the IBM Storwize V7000 V6.3, SG24-7938Implementing the IBM System Storage SAN Volume Controller V6.3, SG24-7933Real-time Compression in SAN Volume Controller and Storwize V7000, REDP-4859SONAS Implementation and Best Practices Guide, SG24-7962SONAS Concepts, Architecture, and Planning Guide, SG24-7963

About this book
To meet today's complex and ever-changing business demands, you need a solid foundation of compute, storage, networking, and software resources. This system must be simple to deploy, and be able to quickly and automatically adapt to changing conditions. You also need to be able to take advantage of broad expertise and proven guidelines in systems management, applications, hardware maintenance, and more.The IBM® PureFlex® System combines no-compromise system designs along with built-in expertise and integrates them into complete, optimized solutions. At the heart of PureFlex System is the IBM Flex System® Enterprise Chassis. This fully integrated infrastructure platform supports a mix of compute, storage, and networking resources to meet the demands of your applications. The solution is easily scalable with the addition of another chassis with the required nodes. With the IBM Flex System Manager®, multiple chassis can be monitored from a single panel. The 14 node, 10U chassis delivers high-speed performance complete with integrated servers, storage, and networking. This flexible chassis is simple to deploy now, and to scale to meet your needs in the future.This IBM Redbooks® publication describes IBM PureFlex System and IBM Flex System available from IBM. It highlights the technology and features of the chassis, compute nodes, management features, and connectivity options. Guidance is provided about every major component, and about networking and storage connectivity.This book is intended for customers, IBM Business Partners, and IBM employees who want to know the details about the new family of products. It assumes that you have a basic understanding of blade server concepts and general IT knowledge.

About this book
The first section of this research is to validate the generality of the existing UW spindle model by study on different size of hard disk drives and under different ambient temperature. Some important phenomena are discovered during the validation. First, different sizes of hard disk drives present special characteristics. The base/cover assembly tends to become more flexible when the size of the hard disk drives decreased. Second, the fixture design is critical for smaller size of hard disk drives. Since some smaller hard disk drives present heavily coupling effect between base and disk modes, more rigid or well clamping type of fixture can reduce the interference to the actual responses of the hard disk drives. Third, the frequency compatible approach is also helpful for systematic study by using the UW spindle model.

    This would have provided a nice upgrade path for juggling data

    I bought these looking for a low-power, high capacity option for a second array in my NAS (first one is 8TB, Raid-5 to 6TB available). This would have provided a nice upgrade path for juggling data.It turns out that this drive is based on a relatively new platter technology (SMR) which doesn't appear to be well supported by standard operating systems just yet.I bought 4, replaced 3, and am now returning the 4 that I currently have (another died, this trend does not seem as though it will end).I noticed that just before failure (after the first one died I started monitoring) SMART feedback would show an ENORMOUS raw read error rate and seek error rate. When I checked the 3rd replacement as I inserted it to rebuild the array yet again, I noticed that those numbers were actually high right out of the box, and ended up enormously higher (starting at say 100 million errors read and 1million seek, ballooning to ~1billion read and ~8billion seek).

    Best upgrade you can give your PS4 for the price.

    Nearly 2 years after buying my launch PS4, I decided it was time to give it a bit of an upgrade on the HDD for not only more room for games though I still buy physical copies as im an old school gamer, but also to give it a slight boost in loading speeds depending on games after seeing comparison tests across the web.Granted the 5400RPM vs 7200RPM difference is not very big in most games, a few seconds shaved off in games like Assassins Creed Black Flag, Shadow of Mordor and Resident Evil vs I saw no difference in Grand Theft Auto 5 sadly. I timed the difference with my smartphones stop watch before and after upgrade. But then again, even SSD's arn't a huge improvement either due to some type of hardware limit Sony put on the system board. I couldn't even hear the HDD working with my ear next to PS4 and I felt no heat difference or vibration increases either, so no worries thereAlso, if your a total data storage hog for games or video sharing, 1 terabyte likely... 5/5 Arct1c0n - See all my reviews Verified Purchase(What's this?)

    Good inexpensive upgrade to 7200 RPM at 1 TB (from original 5400 RPM drive) and with 2-platter (9.5 mm) height

    Bought this to replace the default 5400 RPM 1 TB drive that came with my new Dell Laptop. I had done the same a few years before with my older laptop, replacing the 500 GB 5400 RPM default drive with a 750 GB 7200 RPM Western Digital Scorpio Black, but WD doesn't (or didn't at the time of my purchase) make a 7200 RPM drive in 1 TB capacity so I chose HGST (Hitachi). It was the only manufacturer I could find at a reasonable price that made a 9.5 mm height (2-platter height, important to check this!) 2.5" internal laptop drive at 1 TB 7200 RPM. The current price at $60 seems a steal (I paid double that just a few months ago).Quite frankly, I can't say I noticed a huge difference in speed, but since it was a new computer I didn't have much experience with using it before the upgrade so maybe I would have noticed it more had I used the computer normally for some months before upgrading it.There is no audible sound whatsoever from the drive in normal operation... 5/5 Dancing Feet (Miami, FL) - See all my reviews Verified Purchase(What's this?)
