Three projects have been implemented since the beginning of the year. Of course, this is not the total number of all projects. It is expected that more similar solutions will be deployed by the Partner by the end of the year, and the popularity will last for at least three years (I think ). In this way, I would like to share the full virtualization solution from a technical point of view and some of my humble points of view. Of course, the content only focuses on technology and interests, because I don't want to turn it into a soft article.
I have always adhered to a point of view. If an enterprise urgently needs a set of virtualization solutions, I don't think that my Partner and I really need them because "virtualization" is just a technology, the results achieved through this technology are our needs. For example, we can change the physical characteristics of devices, use them for our purposes, and support more elastic scaling, if there is a better technology tomorrow, and "virtualization" will gradually fade out of sight, but today, it is understandable that this technology is the best.
The complete virtualization solution consists of three elements: desktop virtualization, server virtualization, and storage virtualization. Three elements are not indispensable, but I think they will be perfect if we do three. Especially for integrators, the entire solution will be impeccable, even if our competitors are already in place in PR, without sound implementation experience and technical background, it is difficult to meet customer needs within the same budget.

In terms of the solution and architecture, Let's first look at the topology diagram, and it takes a lot of time to make a graph. ^_^ !)
1) desktop virtualization often represents the end user experience, centralized resource management, and low-cost construction. We can move the office to any internet region.
2) server virtualization makes it understandable for me to bring convenience. In addition to key or special services, we still rely on Minicomputers, and most of the other systems can be deployed on VMS. Currently, the vendor's solution ensures continuous business access, comprehensive resource utilization, and dynamic resource migration.
Frankly speaking, I don't want to show off this part of knowledge, especially for many engineers who are more experienced than me.
The most important thing is my current-storage virtualization. There are a lot of things worth talking about here .........

3) Storage Virtualization is not a stranger. Even if many first-line manufacturers cannot afford to invest in R & D, they have acquired this technology early, it seems that all of these solutions have been developed in this way, and they are well applied to customer needs. More for Small and Medium-sized data centers.
At coffee time, I often pay attention to IT companies that are far away in Silicon Valley. A large number of venture capital companies are happy to join the ranks of high-end storage R & D companies. After these products are put into the market, they can well cater to the customer's needs. A large part of this demand is due to the introduction of Virtualization (I think ). Take VDI as an example: in the future office environment, you only need to put a small box (a bit like Mac Mini) on the desktop of each employee, configure a small amount of cache space, keyboard, mouse, and display, in this way, we can work, without worrying about the stability of PCs and disks. The most important thing is that employees can move the office to a hotel, home, or even a car at any time as needed, as long as you can access the Internet.
What I want to talk about is: when employees use this office environment, the good experience is largely determined by the storage performance, which is the storage that we have already placed in the data center. The introduction of SSD-NAND disks can effectively solve the IOPS problem, but the capacity is smaller, In the VDI as a virtual server to get more extensive applications, expect a larger capacity. OK, what is the cost? What about the customer's existing storage devices? When the customer's demand and maximum payment cannot be balanced, we can try to solve the problem from another perspective, and the final result may be more optimistic than expected.
The core of Storage Virtualization is to first integrate heterogeneous resources to maximize resource utilization. This allows users to get rid of traditional hardware binding and purchase products independently based on their needs and budgets. IT infrastructure, from hardware to software, seems to be the slogan of 2013, but how many integrators can do IT right ?)
Security:
Currently, the best technology is high availability (ensuring business continuity). Master Data and replica data are consistent through real-time image nodes. After a single node fails, the passive node takes over immediately, this ensures business continuity. Highly available nodes can be deployed in the same data center, between two floors, or between the same city. Separated image sites can avoid regional impacts caused by disasters. If necessary, it can be smoothly expanded to the remote disaster recovery site <through IP NetWork>.
Resource Utilization and elastic Scaling:
In the future, you can purchase products based on your actual needs and budget, select disks of different vendors or different characteristics, expand online, replace online, and remove storage devices/disks online. Several devices will be integrated into a disk pool, as shown in the figure. Through the virtualization technology, we can also advance the disk capacity, and all the occupied capacity is subject to the actual data volume.
Get the highest performance with minimal investment:
With the help of storage virtualization technology, we can invest a small part of SSD disks to solve the VM startup or login storm. When each VM requires high concurrency IOPS, it can achieve SSD performance, while the remaining, we can purchase more large-capacity SATA disks: We maintain high-performance storage access while reducing the budget to 60% (which is not an exaggeration ).
Benefiting from virtualization technology, we have gained more auxiliary features, such as storage-type layering (automatic), CDP, load balancing among storage devices, and QoS policies, dynamic resizing, Cache acceleration, Data Migration, streamlined configuration technology, or extended remote disaster recovery sites. In short, flexibility is amazing!
In addition:
I don't want to exclude some vendors that embed the storage virtualization part into the production system. I am not very optimistic about it myself. My trivial experience tells me that even in a smaller solution, the layers need to be clear. If the storage virtualization layer can support performance independently, I think it will be more flexible in the future:
This reminds me of the fact that the customer has been complaining for a great deal about the last few communications with the end customer. A set of solutions are almost perfect in the first place, but each expansion in the future will take a big step, such as the increase in data volume, due to the disk expansion and the huge business volume, the production system expansion cannot be smoothly added to the current environment every time. Every change requires a shutdown application. The customer is tired of accompanying the integrator at night. Even if customers do not have a good term to express their needs, as integrators, they should know that they need their IT environment to support elastic and smooth expansion during the growth cycle, built on minimal downtime.
In fact, what I want to express is that if the storage Virtual Layer built is an independent layer, independent performance and independent workflow, what customers are worried about can be avoided at this moment.
