In terms of high availability, can Xinchang virtualization horizontal expansion hosts be expanded without upgrading the version?In terms of high availability, for Xinchang virtualization horizontal expansion hosts, is it possible to expand without upgrading the version? Because in our bank’s Xinchang virtualization, the expansion hosts must upgrade the virtualization software version, which causes a lot of trouble.
The question comes from community member @xjwangbo100, a system architect at a city commercial bank. The following shares are all from community members.
@bkw, an operations position at a national joint-stock bank: Focusing on stability, the manufacturer insists on upgrading the virtualization software version for a reason, so I recommend upgrading.
@Effort to Move Bricks, a system operation engineer at a joint-stock bank: Currently, mainstream Xinchang virtualization products do not require this; horizontal expansion of hosts is a common feature of virtualization. The manufacturer can optimize it well so that a single upgrade can solve the problem. Otherwise, with the Xinchang transformation, horizontal expansion of hosts will be very frequent. Continuous upgrades will put a lot of pressure on operations and maintenance.
@Fresh Feel, a cloud platform operations management position at Beiyin Financial Technology:
1. If the expansion host must upgrade the virtualization software version, the manufacturer needs to provide a specific response and clarify the specific reasons, then see if it can be accepted, also to rule out the possibility of security risks existing even without upgrading. Under normal circumstances, expansion is expansion, and upgrades are upgrades; they should not be confused.
2. It is still recommended that the manufacturer upgrade the virtualization product while ensuring the stability of the production environment. On one hand, upgrades fix bugs at the virtualization platform level, and on the other hand, they can strengthen security and fix vulnerabilities at the underlying level. Especially with the increasing requirements for security, upgrades should be made; otherwise, the gap between versions will make future work harder to advance.
@yyf123, a system engineer at Weihai Commercial Bank:
Regarding the issue of whether Xinchang virtualization horizontal expansion hosts must upgrade the virtualization software version, we have encountered this before. The situation at that time was that the microcode version of the new hardware was too new, causing the old version of the virtualization software to be unsupported, and ultimately, it could only be resolved through an upgrade. If it is another situation, in my understanding, for mainstream domestic virtualization software, expansion hosts basically do not need to upgrade the virtualization software version. This also indicates that in most cases, users can directly add new hosts to the existing virtualization environment without worrying about compatibility issues or additional software update costs.
@mxin, a senior engineer at Shanghai Baoxin Software:
Generally speaking, whether Xinchang virtualization horizontal expansion hosts can be expanded without upgrading the version depends on the specific virtualization product and technical implementation. Some Xinchang virtualization products are designed to support horizontal expansion without version upgrades, while others may require upgrading the virtualization software version due to technical architecture or functional implementation reasons. The situation faced by the bank where the expansion host must upgrade the virtualization software version may be due to specific limitations or requirements in the architectural design or functional implementation of the Xinchang virtualization product used by the bank, which necessitates relying on software version upgrades to ensure system stability, compatibility, or performance. This may cause some trouble for the bank’s system operations and upgrade work, such as increasing the cost of upgrades and potentially affecting the normal uptime of the system. If you want to avoid such situations, you can consider choosing Xinchang virtualization products that support more flexible expansion methods in their design, or communicate with the virtualization product suppliers to understand if there are other solutions or optimization measures to reduce the impact of version upgrades on expansion work. At the same time, when planning and implementing Xinchang virtualization projects, the system’s scalability and upgrade needs should be fully considered, and technical selection and solution design should be done in advance.
