Extend Your Data Center’s Life Cycle

With the steep rise in energy costs, data center operators and their clients are recognizing energy efficiency as key for future growth. Managing a data center’s hardware life cycle is an ongoing process and needs to be constantly updated. Costly failure rates and downtime can be avoided by identifying and isolating hotspots and inefficient devices prior to implementation and equipment upgrades. Introducing cooling simulation early in your design process can reduce your data center cooling costs.

A typical server service life is about three to five years, but that number can now be as long as eight years. Some data centers are so impoverished that servers must run even longer than that.  Machines require increased maintenance as they wear down. But this increases data center costs. So the question is, how can data center engineers extend the life of their machines while keeping everything cost effective?

The methods to  extend the life cycle of the data center would be as follows:

  •  It is much needed to make sure we get the most from existing technology. We need to take advantage of the best practices such as proper room sealing, the hot-aisle/cold-aisle rack arrangement, and preventive maintenance to optimize the performance of the existing data center cooling system. Installation of a supplemental cooling infrastructure is the next step. This would indeed extend the facility life and delay the need to build a new data center.
  • Using the right size building blocks is essential, as the input power to the facility will ultimately determine how much equipment can be supported. As an example, by analyzing the power system reliability of a multi- module UPS configuration, it is recommended that the UPS modules be sized no less than one-third of the total facility load.
  •  Older machines require extra care because with older hardware, the little things can make all the difference. To help the system run longer, several tasks need to be completed at least once a month. For example, make sure that all operating system patches, updates, drivers and roll ups have been deployed; the antivirus system has been updated and is operational. Now with better technology and resources, this can be accomplished more easily and cost-effectively than ever.
  •  It is quite tricky to predict what technologies a data center may have to support in the next 10 years. The best approach would be to employ adaptive technologies that would give us the most flexibility to respond to change. Though availability is still the No. 1 factor in infrastructure design, flexibility is now a close second.
  •  If a server uses local storage, run the Disk Cleanup as well as Defragment tool to help the machine run longer with stable data and a cleaner running drive. Running hard drive health checks on a regular basis, regular inspection of hardware components within the machine and making sure all fans are operational and verify that all components and cable headers are in their place is very essential. There is also a need to keep an eye on dust buildup as this can quickly interrupt cooling and cause electrical glitches that can affect the server.
  •  To provide valuable intelligence and control at both the rack and room level, the monitoring systems have improved beyond simple alarming. Intelligent controls in computer room air conditioners now enable multiple units in a room to work together as a team, increasing system efficiency. Intelligent power strips provide receptacle-level visibility and control of equipment power on the rack level.
  • It is necessary to stay vigilant. The past experiences have shown that the equipment with a robust maintenance program experience reduced downtime and clearly extend the life of their data center equipment. Also, consider regular data center assessments to monitor the impact of new technology and ensure supporting technologies and best practices are current.

Optimization of the electrical and physical environment will assist any server work for a longer duration. This includes the following important factors: electricity, temperature and air quality:

  •  Electricity quality plays a key role in determining the longevity of a machine. To maintain healthy operation of the machines, managing the amount of voltage entering the server room is very critical. A sudden spike can severely damage computers. Using a good uninterruptible power supply and power regulators will help to monitor the amount of input voltage to the machine, or a rack of servers.
  •  The room temperatures for normal operation of most servers should be between 60 to 85 degrees Fahrenheit. A steady humidity level between 50 and 75 percent should be maintained. Proper management of the environment in a data center would increase performance of the machines inside and also allows them to have longer operational life.
  •  Air quality is also very important with computers as proper air circulation could prevent its overheating. It is much needed to keep good airflow around your machines. Servers need to be moved away from walls to allow vents to properly circulate hot and cold air.

Switch to SaaS-Its Simply Better

Software as a service (SaaS) is commonly referred to as “on-demand software”. It is a software delivery design in which software and related data are centrally hosted on the cloud. SaaS is generally accessed by users using a client through a web browser. Software as a Service is a surfacing system of delivering software applications to customers through the Internet. SaaS or On Demand software can be executed to reduce the ongoing costs that conventional applications entail.

Why is it so important to switch to SaaS? Because of the numerous benefits which cannot be ignored. Some of them are:

Cheaper pricing entry:

Unlike conventional software which is traditionally sold as a long-lasting license with an up-front pricing and an optional ongoing support fee, SaaS suppliers normally charge applications using a subscription fee, commonly stated as a monthly or an annual fee. Accordingly, the preliminary setup cost for SaaS is normally lower than the corresponding enterprise software. SaaS merchants on average price their applications based on some usage factors, such as the number of users using the application. Nonetheless, because in a SaaS environment users data resides with the SaaS merchant, prospects to charge per transaction, incident, or other unit of value widely exists.

 Global availability:

The equipment subsists to make on-premise software accessible outside the premises as well and not just accessibility but also functionality that are obtainable from anywhere on the internet natively. It is global at the core but flexible to meet local requirements. SaaS applications are available from any computer or any device anytime, anywhere. This is because; most users know how to find what they need on the Internet. SaaS application tends to have high adoption rates, with a lower learning curvature. Improved access to data from any networked device makes it easier to manage privileges, monitor data use. It also guarantees that everyone can access the same information at the same time from anywhere.

Multi -resident competence:

SaaS equipment is a multi-tenant architecture. This means that the cost of all software, infrastructure and expertise is shared by a large number of regulars. This improves the implementation speed and cost effectiveness of the application dramatically. SaaS applications are developing at a rapid rate because developers are focused on what’s next rather than on maintaining numerous versions of old code.

Easy Upgrades: 

Since the SaaS source manages all updates and upgrades, there are zero possibilities of hitch for the customers to download or install. The SaaS provider also manages availability, so there’s no need for customers to add hardware, software, or bandwidth as the user pedestal grows.

Enlarged convenience and Productivity:

Web based applications facilitate users to save information on the Internet, hence making it easily available from anywhere. The business knowledge is made accessible to all employees thereby increasing combined productivity. Physically unconnected teams function better with better information accessibility. The other aspect is the decline in data center hassles incurred by software consumers in the conventional client/server model.  This leaves data center workforce to focus on improving the day-to-day technical operations of the firm instead of being called upon to troubleshoot mediating party.

Flawless Integration: 

SaaS merchants who have the right multitenant architectures can range indefinitely to meet client demand. Many SaaS suppliers also offer customization competence to meet explicit needs. The popularity of SaaS is steadily increasing because it simplifies deployment and reduces customer acquisition costs. With SaaS, developers can hold up many regulars with a single version of a product. This process is known as multitenancy. This enables companies to scale as fast and as much as needed without replacing the costly infrastructure or adding extra staff. Because of the way SaaS is designed, these customizations are exclusive to each company or user and are always preserved through upgrades. That means SaaS providers can get upgrades more often, with low customer threat and much lower implementation cost. Customization is simple with point-and-click simplicity; making the old fashioned update ritual of ‘waiting’ practically non-existent.

Enhanced Security:

Software as a Service providers are in the business of providing continuous reliable services. Sellers recognize that data must be backed up consistently, and information security is of extreme precedence. Competent resources, network redundancies, stand-by power, up-to-date security and intrusion detection are compulsory infrastructure required to provide an enterprise class service. This is the kind of security that the SaaS provides its users.

The Rise of Server Blades

The Server Blades is the fastest growing segment of the worldwide server market. It is expected to continue to grow at a higher rate according to Industry analysts and researchers. Project venture data centers seek out to these servers which provide benefits to companies. Benefits of the new platform include power cooling, and server consolidation that maximize the compute power per rack unit. As a result, effectively incorporating these devices into the data center system construction becomes an important element for the system administrators to consider.

The advantage of Blade servers is that it offers a consistent method of deploying multiple memory, processors, and I/O resources. Hence, it replaces those resources on plug-in boards that slip into a standard chassis. They share common resources like power, storage and I/O across multiple processors thereby reducing cost versus separate server systems. In the server market, the demand for blade servers has rapidly increased with time. IT departments have encountered their ultimate vehicles to increase server density. They are also achieving higher control over operation, deployment, provisioning and advancing large server farms. What has made Blade servers so alluring is the fact that they offer a permutation of reduced cost, competent use of costly data center space, cut down management for various servers, and greater performance over time.

Blade servers are the recipient force behind several key elements of computing technologies. All of it ranging from inflated processor densities in single-chip multi-core semiconductors, to bunch computing techniques, and 10 GB Ethernet deployments.

Data center managers are making the best use of Blade servers’ various capacities. The ability of the servers to deeply increase both the quantity and the competence of computing, memory and I/O resources is a boon to data centers. These services increase the ever demanding user productivity. It has given an augment to a new set of software tools, both in server resource management and server desktop virtualization applications. In addition to this, the rising densities of blade server-based data centers has led to the growth of a fresh set of challenges in the power and cooling of contemporary data centers. As a result, power vendors are forced to extend new technologies and solutions for power management and efficiency.

Server blades include two major technologies – integrated switches and pass-through technologies.

Integrated Switches

Blade systems permit built-in switches to manage traffic flow between the blade servers within the chassis and the remaining enterprise network. Blade systems provide a variety of switch media types that includes the following:
• In-built Ethernet switches
• Infiniband switches
• Fiber conduit switches

Integrated switches are a passage to the blade servers inside the chassis and the data center. Every blade server is connected to a backplane or a mid-plane that normally contains four committed signalling lane to redundant network devices dwelling in the chassis. This definite physical structure decreases the number of cables necessary by each server and supplies a level of resiliency, which is done through the physical redundancy of the system interface controllers (NICs) and I/O system devices.

Pass-through Technology

 It is a substitute method of network connectivity that permits individual blade servers to correspond openly with external resources. In this technology, both copper and optical pass-through modules that supply access to the blade server controllers are offered. There are two common types of pass-through I/O devices, each of which provides connectivity to the blade servers through the backplane or the mid-plane of the chassis. There is a one on one relationship amid the number of server interface amongst the numeral peripheral ports in the access deposit. These server interfaces are required to maintain the blade system.

Pass-through components are passive devices that casually expose the blade server NIC to the external network. They do not need configuration by the network administrator. Also I/O devices are not required in these configurations. It is also not extended to network Layer 2 or Layer 3 topologies. In addition to this, the blade servers may utilize any of the NIC teaming configurations sustained by their drivers. The necessity to decrease the amount of cabling in the data center is the most essential influence driving the swift implementation of blade servers.

Pass-through modules never allow the data center to take added benefit of the cable consolidation the blade platform tenders. This short of cable fall out in the rack/ row/ provision frequently hampers the employment of a pass-through foot solution in the data center.
