Migrating to Blade server are you ready for the following four points?

Http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server Reduces hardware components and saves data center space by compressing power and traditional server bulky bodies onto a high-density circuit board. Inserting more than 10 blades vertically into a 8U or smaller chassis and then being lightly pushed into a 42U high standard server cabinet allows the user to maximize the computational resource density.

Blade servers are also more flexible and easier to manage than traditional rack-mount servers, and can be replaced with different pre-configured blades in a single blade chassis, depending on the business requirements.

In order to allow the computer room to accommodate the higher the computational density, so that the power consumption of unit computing capacity is lower, so that the server is more easily managed ... And so on, the reason is that the user will be the original data center of the traditional tower, rack-style migration to the blade server. According to IDC data, this year, the global blade server market will be larger than the rack-server market for the first time.

The upcoming 3G communications services, broadband multimedia services and other web-based, multimedia market expansion will promote the IT infrastructure market development, these types of business will also bring the blade server a larger market development space.

Similarly, in some emerging business areas, because of the need for fast, rapid development, and the requirements of the system to operate stably, it is very suitable for the blade server to display their fists.

Evaluation and analysis of blade migration

The advantages of blades are so obvious, what should users be aware of when migrating existing applications to blades?

The blade's requirements for the environment are far beyond the original rack server, and if improper consolidation results in an overload of the application environment. Therefore, it is important for IT managers to take some time to conduct a needs assessment to understand the actual business needs and related parameter selections to determine the device bottlenecks. This is especially true for deploying blades in existing data centers.

Based on the above requirements and constraints of consideration, from the rack, refrigeration, power supply and management specifications to specify.

Cabinet and floor

The most obvious advantage of a blade server is that its deployment density can exceed the 1U rack server, and the performance of the server is increasing, but the power dissipation problem can not be underestimated. First, the rack/cabinet must be compatible with the blade server chassis, while providing enough power and data lines for the blade server, as well as ensuring airflow to and from the rack.

Based on the application characteristics of the blade server, APC Netshelter VX is the recommended rack solution for all deployment methods. Netshelter VX has a good compatibility base, supports 907 kg of load, reserves four vertical PDU (0U space), and has a 66% (0.516 sqm) hole punch to provide adequate refrigeration to the equipment. Netshelter VX also supports power and data line top alignment, rack cable management, and airflow distribution.

High-density deployments are not just a requirement for new standards for power supplies and air-conditioning, but also for the floor in IDC. The standard weight of each blade server is 100 kg, this weight will be further increased with the configuration of the blade module, to know that the space of 42U cabinet can accommodate up to 6 too big, and the weight of the stack makes you have to consider the load-bearing of the floor of the room.

Refrigeration

Refrigeration is the most critical factor in the deployment of blade servers. The front part of the blade server tray (chassis) needs to have enough cold air to enter, while the following part requires the same amount of heat to be taken away. Specifically speaking, the refrigeration scheme should not only consider the inlet temperature required by the blade, but also consider the airflow.

APC has two airflow distribution products can increase the cooling capacity of the rack, that is, APC's Airflow Distribution Unit (ADU) and APC's rack-type strong exhaust unit (ARU). At the same time, APC's Networkair IR is a precision refrigeration air-conditioning, from the back of the cabinet (hot channel) to the hot air suction, cooling side to the cold channel. This will increase the rack density because the system is no longer subject to the amount of airflow that the perforated floor can provide. For high-density loads, the In-row system will be assembled into a hot-channel fence system that includes a roof and a suite of door-mounted doors to completely close the data center's hot channel and eradicate all gas blends.

Power

Proper determination of the power required to deploy the blade server requires a comprehensive consideration of the power supply capacity and the distribution of the power supply to the rack. But the more challenging fact is that the deployment of blades is increasing over time, and the amount of future load is usually unknowable. Power Distribution products must take into account monitoring to avoid dynamic power changes to the upstream circuit breaker failure.

In addition, it is recommended that you use a monitored distribution cabinet when deploying blades to monitor the branch current to ensure the redundancy of AC power. In order to fully utilize the redundancy of power distribution cabinets, it is necessary to provide input power supply for different UPS/PDU power supply to achieve a 2N system assembly. At least two ports are required to provide redundancy for the circuit breaker switch of the distribution cabinet.

Management specification

Reliable NCPI (Network-critical infrastructure) systems need to monitor many data points, which is also a specific requirement for blade applications for usability. The power supply, rack, and refrigeration components of APC's Infineon integrated systems are built with remote management capabilities for easy and affordable access to individual devices. The Infineon manager with APC can centrally manage up to 1000 APC devices in the same network. A stand-alone IP network can access up to 253 APC devices via an IP address. The existing situation can be evaluated quickly, and the person concerned is notified when the existing condition may pose a threat to availability. Analytics can help with planning for availability, power, uptime, and refrigeration requirements.

Efficient management of high-density NCPI facilities allows users to identify problems early in the event of power and temperature anomalies, and to correct them in a timely manner before they cause downtime, thus greatly increasing the availability of the overall system.

Conclusion

How to apply blade server in high-density environment has become an important link in the planning of modern data center. When users take into account some of the issues listed above, the conditions required, and the implementation of the relevant optimization scheme, it is more attractive to install blade servers in existing facilities, as this can save both cost and time and reduce disruption to the normal operation of existing data centers.
