Quietrock Case Study | Sony Computer Entertainment America
Studios & Entertainment Quiet® Success Story Project: ® Sony Computer Entertainment ‘Sh-h-h-h!’ PlayStation 4 game- America, LLC making in progress! Location: San Mateo, California New sound studios spearhead renovations for Sony Computer General Contractor: Entertainment America, with an acoustical assist from Magnum Drywall Magnum Drywall and PABCO® Gypsum’s QuietRock® Products: QuietRock® FLAME CURB® San Mateo, California The Sound of Silence means a lot to engineers producing video games for Sony PlayStation®4 (PS4™) enthusiasts. At Sony Computer Entertainment America LLC headquarters in San Mateo, California, producers’ tolerance for intrusive noise from beyond studio walls is zero. Only the intense action on-screen matters while creating audio effects that dramatize, punctuate and heighten the deeply immersive experience for video gamers. In these studios Sony Entertainment sound engineers make the most of that capability while keeping the PlayStation® pipeline full for weekly launches of new games. The gaming experience draws players to PS4™ and its predecessor PlayStation® consoles, and PS4™ elevates 3D excitement ever higher. It’s the world’s most powerful games console, with a Graphics Processing Unit (GPU) able to perform 1,843 teraflops*. “When sound is important, we prefer to submit QuietRock as a good solution for the architect and the owner. There’s nothing else on the market that’s comparable. I even used it in my own home movie theatre.”” – Gary Robinson, Owner Magnum Drywall what the job demands Visit www.QuietRock.com or call Call 1.800.797.8159 for more information On top of its introductory lineup in November 2013, over 180 PS4™ games are in development, including “Be the Batman”, the epic conclusion of the “Batman: Arkham Knight” trilogy, that is due out in June 2015. -

Virtual memory management http://en.wikipedia.org/wiki/Virtual_memory Virtual memory is a computer system technique which gives an application program the impression that it has contiguous working memory (an address space), while in fact it may be physically fragmented and may even overflow on to disk storage. Developed for multitasking kernels, virtual memory provides two primary functions: Each process has its own address space, thereby not required to be relocated nor required to use relative addressing mode. -

Zoned Storage for HDD and SSD Technologies
Zoned Storage Now Encompasses Both HDD & SSD Technologies WHITE PAPER 3 Western Digital | WHITE PAPER WHITE PAPER Zoned Storage Now Encompasses Both HDD & SSD Technologies Both HDDs and SSDs have their own on-device controllers that are used to provide low-level manipulation of the drives. The division of compute tasks performed by the host-side CPUs and the drive-side controllers has evolved over time, with the boundaries moving back and forth between them. Computational architectures have evolved, especially in data centers where — as systems started to scale — local optimizations performed by the devices began to impact global optimizations. The concept of Zoned Storage is a relatively recent development that refers to a class of storage devices — both HDDs and SSDs — that enable the host system and the storage devices to cooperate so as to achieve higher storage capacities. As its name suggests, Zoned Storage involves organizing or partitioning the drives into zones. In the case of HDDs, Zoned Storage is implemented using a technology known as shingled magnetic recording (SMR). In the case of SSDs, Zoned Storage is implemented using a technology known as Zoned Namespaces (ZNS). Data Taken As-Is Serialize Data Zoned Storage Zoned Storage 2 HDDs An HDD contains one or more rigid rapidly rotating platters coated with a magnetic material. Electromagnetic read/write heads are positioned above and below each platter. Data is stored on the platter as a series of thin concentric rings called tracks. In turn, the tracks are sub-divided into sectors. The HDD also contains a hard disk controller (HDC), which may be thought of as a small processor that is used to provide low-level control of the drive. -
Garbage Collection Understanding Foreground Vs
Garbage Collection Understanding Foreground vs. Background GC and Other Related Elements Kent Smith Sr. Director of Corporate Marketing SandForce Flash Memory Summit August 2011 Santa Clara, CA 1 Understanding Garbage Collection (GC) • In flash memory, GC is the process of relocating existing data, deleting stale data, and creating empty blocks for new data • All SSDs will have some form of GC – it is not an optional feature • NAND flash cannot directly overwrite a page with data; it has to be first erased • One full block of pages has to be erased, not just one page • GC starts after each page has been written one time • Valid data is consolidated and written into new blocks • Invalid (replaced) data is ignored and gets erased • Wear leveling mainly occurs during GC Source: Wikipedia Flash Memory Summit 2011 Santa Clara, CA 2 How the OS Deletes Data • The OS tracks what files are present and what logical blocks are holding the files • SSDs do not understand the file structure of an OS; they only track valid data locations reported by the OS • When the OS deletes a file, it marks the file’s space in its logical table as free ► It does not tell the drive anything • When the OS writes a new file to the drive, it will eventually write to the previously used spaces in the table ► An SSD only knows data is no longer needed when the OS tells it to write to an address that already contains data Flash Memory Summit 2011 Santa Clara, CA 3 Understanding the TRIM Command • The OS* sends a TRIM command** at the point of file deletion • The SSD marks -

You can resolve these issues yourself using the Exadata Cell rescue functionality provided by Oracle on Exadata Storage Server Software CELLBOOT USB flash drive. The whole procedure is quite straightforward, but enough due diligence must be done to make the recovery a delightful experience. Oracle performs automatic backups of the operating system and cell software on each Exadata Storage Server without any Oracle DMA or operational process intervention. The critical files from the storage cells are backed up into the internal USB drive called CELLBOOT USB Flash Drive. The internal USB (/dev/sdm) maintains the most recent configuration and the updated copy of the OS and storage cell software. The internal USB serves as the default first boot device. The Master Boot Record (MBR) and GRand Unified Boot loader (GRUB) are loaded from the USB.
