Step by step, written before the data center upgrade

East and West

At present, the digital economy has become a new competition track, and the official launch of the “East and West” project not only shows the importance of digital resources, but also the data center, which is the main carrier, has also become a “must-be-guarded city” for enterprises and operators. “.

policy level

Looking at the policy level, the “Guiding Opinions on Accelerating the Construction of a National Integrated Big Data Center Collaborative Innovation System” proposes that the operating power utilization efficiency of large and ultra-large data centers should be reduced to below 1.3. However, Beijing requires the closure of storage and backup data centers with an average annual PUE > 2, and the remediation of data centers with PUE > 1.4… This is undoubtedly “worse” for the old data centers.

In other words, as “green” becomes the key word in the future of the data center industry, the road ahead for enterprises and operators is becoming clearer: how to complete the upgrade of the data center on the existing basis?

Step by step, written before the data center upgrade

The transformation and upgrading of the data center involves many aspects such as hardware facilities, operation and maintenance software, and operation and maintenance processes. How to do more with less? Four steps of homework need to be done before the renovation.

Lay the base

Multi-party expedient standard

For existing facilities, one of the problems faced by business owners is that the operating characteristics set earlier are difficult to adapt to existing needs. For example, for a data center whose single unit has expanded nearly 10 times, the management of massive equipment is difficult to measure, and there is a serious shortage of professional operation and maintenance personnel…

At this time, re-evaluation is particularly necessary, and the complete performance standard should not only consider the availability of infrastructure, but also adapt to commercial needs and even energy efficiency standards. Specifically, the following key drivers can be considered:

  • Business downtime cost/risk, i.e. tangible and intangible costs
  • Initial investment, operating cost budget and cost reduction measures
  • “Green” initiatives such as carbon reduction or power usage efficiency (PUE) targets
  • Industry expectations and peer initiatives

At this stage, it is necessary to understand the focus of the business and reserve space for subsequent capacity and expansion capabilities. The following figure is an example of common performance standards focusing on availability for your reference.

Comprehensive assessment

Identify gaps and risks

After the standard is set, the next step is to evaluate the gap between the existing facilities and the standard, including the actual investigation of the infrastructure equipment, the collection of equipment data, and the verification of their interconnectivity. continuous running time, etc.

Step by step, written before the data center upgrade

It is worth mentioning that in the evaluation, not only should we rely on drawings or written reports, but also understand the workflow and methods of the operation and maintenance team, and evaluate the current assets and operation and maintenance from a global and omniscient perspective. Not only that, aging equipment will bring more serious downtime risk, so it is necessary to fully understand the current load and future growth plans, and even use a scoring system to weight and risk score each project.

set a strategy

Weigh the pros and cons to make up the difference

Once all performance gaps and health risks have been identified, the next step is to identify solutions. For example, in the face of a batch of aging UPS scenarios, we have three ways to solve the problem:

  1. direct purchase
  2. Upgrades keep UPS longevity and performance
  3. Maintain the status quo except for the most basic maintenance

If there is a significant change in capacity or redundancy requirements, the maintenance cost is too high, the cost-effective upgrade is low, or there are subsequent considerations for improving energy efficiency, then method 1 can be considered. Similarly, we can also use this idea to consider all data centers. subsystem.


order of importance

After the above steps, if you cannot take action on each item, you need to prioritize what is important and urgent, and what can be put aside first. The effective way is to evaluate according to the following conditions:

  • Level of risk to continued normal operation of IT equipment
  • The cost of implementing the change
  • Time to implement the change (work resource)
  • Feasibility of implementing changes in operating facilities with minimal disruption

High-risk gaps are clearly the priority, followed by a trade-off between costs, time, and long-term disruption. Here is also a simple example for everyone to identify gaps based on standards and red, yellow, and green codes.

Step by step, written before the data center upgrade

Today’s data centers have fundamentally changed in terms of scenarios, operation and maintenance, and the relationship with energy. The aging of equipment has increased the risk of business downtime, especially in the process of intensive development, once the downtime is not only business shutdown, but also more likely Affect the operation of upstream and downstream, resulting in more serious economic losses.

Therefore, it is particularly important to promote the data center to develop on the road of high availability, high efficiency and sustainable development through upgrading and transformation. However, as a business center, upgrading and transformation are still full of challenges. Shijia will work with you to face the challenges and move towards a more sustainable sustainable future.
