the recent work involves anroid porting to 6410. Since there is only one Development Board for others to debug first, I will first make up the basics of Flash Driver. first, the number of accesses. In theory, the MLC architecture can only handle about 10 thousand data writes, while the SLC architecture can withstand about 0.1 million data writes, 10 times that of MLC. This 10 thousand refers to the number

Solid-State drive with its own advantages such as ultra-fast access rate, by more and more computer enthusiasts favor, and quickly spread to the vast number of users of the computer, because the solid-state drive and traditional mechanical hard disk compared to the efficiency of the operation has been a qualitative improvement, but also is the United States network small to remind everyone is, Buy solid-state drives can not blindly follow the follow-up, to ensure that the solid-state drive to un

SSD (solid State Drives), or SSD, is a hard disk made of solid-state electronic memory chips, consisting of a control unit and a memory unit (flash chip or DRAM chip).SSD storage media are divided into two, one is the use of flash memory (Flash chip) as an access medium, the other is the use of DRAM as a storage medium.SSDs are divided into three types of storage crystals: SLC, MLC and TLC.SLC is all called single level Cell, storage unit 1bit/cell, t

In the U disk, SSD and other solid-state storage products, flash chip particles is the core, which relates to product costs, life and speed. Flash chip particles are mainly three types, respectively, SLC, MLC, TLC, the difference between the three, as follows. What is the difference between SLC, MLC, and TLC flash chip particles? SLC = Single-level Cell, that is, 1bit/cell, long life, the price is expensi

-state drives have a short lifespan? SSD Flash has a problem with the number of write-down limits, which is what many people have criticized for their short lifespan. Flash memory is completely erased once called 1 times P/E, so the life of the flash memory is in P/E units. 34NM of flash memory chip life is about 5,000 times p/e, and 25nm life is about 3,000 times p/e. Does it seem to have a shorter lifespan? This is theoretically true, but with the upgrade of the SSD firmware algorithm, the new

Should you deploy Linux on the mainframe? Many positive and negative feedback on the Linux mainframe confirms that the Linux mainframe is not suitable for all IT departments. The two experts have begun to talk about what is appropriate for the data center: running Linux workloads on the mainframe or running them in a d

Do you know about Linux? Maybe you are a user of the Linux operating system, but do you know how the Linux operating system is managed on the mainframe? This article describes the complexity of Linux management on the mainframe. What is mainframe performance management? In the past, there was no difficulty in answering questions from

At the beginning of the rise of the mainframe, its use environment was extremely secure. You can connect the terminal system to the mainframe so that the mainframe can control the access paths and permissions of data storage and the user's usage information and sources.However, today we are using a Service-Oriented Architecture (SOA). A series of computers send r

In the past 10 years, IBM has launched a series of Business-class, BC) servers to reduce the high overall cost of mainframe access and property rights, at the same time, it can also break into some medium-sized enterprises. To this end, IBM recently released a small, affordable, and entry-level BC mainframe-zEnterprise 114, a bit similar to the previous z800s and z890s. This article will focus on what the I

Many examples of performance management have taught us that slow system performance is no less damaging than a single day, but it is relatively easy to resize a database on a mainframe, and it usually takes a little time to get a larger performance boost. As time goes on, manufacturers have added many ways to perform database reorganization without user intervention, making the reorganization easier for users to ignore, until the database response is

"Mainframe + Linux" for integration-Linux Enterprise Application-Linux server application information. The following is a detailed description. How can we integrate the load of hundreds of servers running across regions distributed across hundreds of branches? At present, the platform that combines large hosts with Linux should be a relatively ideal solution. Hannaford Brothers is headquartered in Maine and operates 200 supermarkets, Food and Drug st

IBM's large machines are looking for new looks. They have upgraded to the private cloud and hybrid cloud markets, providing faster processing capabilities, lower prices, and improved memory. The new zEnterprise mainframe is zEC12 and the processor is 5.5 GHz, which is much better than z196. IBM also extended level 2, level 3, and Level 4 buffering and improved boot settings. This means that zEC12 is faster than z196 and can run more data. These chang

First, let's start by saying where the noise from a mainframe computer comes from. We know that the main components of computer host include: Processor, memory, video card (set video card ignored), motherboard, hard disk, power and other computer hardware, easy to generate noise accessories mainly include: The processor (mainly cooling fan), graphics (mainly independent graphics), the last hard disk may also be memory. Memory this piece actually out o

Goal:Need to know if a goldengate version can support DB2 v11 on IBM mainframe z/OS 2.1? Solution:There are currently goldengate versions to support z/OS 2.1 -11

According to foreign media reports, recently, IBM released its Z13 mainframe platform, the new product equipped with a variety of chip hardware innovation technology to achieve mobility, analytical applications and security-driven workload acceleration. The Z13 system can support up to 10TB of memory and up to 8000 virtual servers.John Birtles, director of IBM System Z Business Development and Technology, explains: "We have invested more than $1 billi

About the virtual mainframe under Linux.We know that the Linux operating system is currently widely used on the server. is the virtual host under the Linux operating system what we often call a Linux virtual host? In fact, technically speaking, it's a virtual environment that's installed on Windows, and it's actually just a file. Let's look at some things about Linux and virtual hosting. First, let's look at the advantages of a Linux virtual host.Adva

The DB2 tutorial you're looking at is how to access the DB2 9 data server on a mainframe, mini-machine. The basic feature of the Database connection tool software DB2 Connect is to provide a way to connect interactive access between the database servers of the desktop application and the service host. The environment in which these desktop applications reside can be either windows,linux, or any of the UNIX. The personal version of the DB2 Connect to

Vendors have recently begun to boast some conflicting ideas about mainframe migration. However, this will facilitate cross-platform applications on the mainframe. Concept of mainframe migration The key to mainframe migration is to provide a convenient way to port applications to Windows or Unix platforms at the sourc
