SCM - Storage Class Memory High-speed non-volatile data storage devices
As a rule, suppliers of DWH apply high-speed non-volatile data storage devices (Storage Class Memory, SCM) as an initial disk cache, however today two-port SCM drives began to be used as storages for permanent data storage, having competed with a flash storages
2020: Five applications which will be benefited from use of SCM memory
SCM quickly leaves a standard cycle of hype which usually accompanies each new technology, and passes into a stage of real life application. What benefits are provided by this technology? It is obvious: break in performance. In combination with the newest protocols of storage — NVMe and NVMe-oF — it allows to cut by half the general response time of a system. A part of suppliers already began to complete the server solutions and DWH with a layer of SCM, they also offer different models of implementation and support of availability. Usually servers are delivered with the one-port SCM drives integrated in their[1]
Some producers DWH are set such the ustroyst as an initial disk cache, and together with it two-port SCM drives appear — apply them as a permanent layer of storage, similar to application a flash storages.
Certainly, SCM and their opportunities — are not free therefore there is a question: how to derive the greatest benefit from this technology, considering the related margin on an innovation? Five business applications to which implementation of SCM will give acceleration are included below.
1. Applications for armoring in real time
The quicker reaction to the address of the client, the bigger satisfaction he feels. Modern users are so spoiled by technologies that expect instant responses on the requests. The same treats also business: if loading of the medical record takes too much time, it causes serious alarm in health workers. Even several seconds increased by hundreds of clients or employees can pour out long minutes of waiting, and it is just that case when SCM helps not to allow dead time.
2. Applications for the stock exchange trading
In relation to programs which are intended for the stock exchange trading, time is in literal sense money. The it is less than a response time — the quicker the bargain is confirmed and concluded. Microseconds can be wrapped in millions of dollars depending on price movement of execution of the transaction. To be competitive, these applications need the fastest response time.
3. High-performance databases
Big databases and some types of programs SQL ERP can also significantly benefit from performance improvement. In process of growth of amount of data also the size of databases grows, they become more distributed and to them access from the bigger number of places is required. As a result, even small deceleration in processing leads to decrease in overall performance. SCM helps to solve these problems without significant changes of IT architecture.
4. Analytics of real time
Still scopes of SCM — detection of fraudulent transactions or marketing applications which are extremely sensitive by the time of accomplishment. These are only two examples of how the analytics of real time changes a business method. Such type of analytics is a game on microseconds when the value of operational improvements easily outweighs the increased costs for the equipment.
5. Applications for Big Data
Splunk applications are analyzed and visualize the data collected from a set of different sources, such as websites, applications, sensors, devices, etc. what, actually, and IT infrastructure and business consist of. As a rule, these applications have the latest data at the level "hot/warm" to which the bulk of search queries is executed. Quick search is crucial for the analysis and visualization in real time, and SCM allows applications of Big Data to reach the processing speed level unprecedented earlier. SCM in combination with machine learning and artificial intelligence provides consolidation of workload.
Systems which can optimize and distribute intellectually data — to place them on suitable carriers in due time — will bring huge benefits to the enterprises. As show calculations, 90% of input-output operations are performed at the expense of 10% of data. IT specialists can provide the best response time almost for all users, at the same time consolidating the IT infrastructure and reducing its size.
As well as in a case from any other curve of mastering of technologies, in the beginning SCM will begin to apply to service of specific applications, and then when the prices of innovation begin to fall, will expand a scope. The marked higher than five applications are extremely sensitive to time of processing and can become the first candidates for that SCM inhaled in them new life.
