Blade servers

Blade servers, also referred to as blade systems, are developed to maximize performance and save space, while maintaining the possibility of expanding and upgrading the server hardware. Thanks to this modularity, these ultrathin and powerful servers are ideal solutions for medium-sized and large companies whose demands for computing power change “every other day”. Blade servers differ from traditional servers in hardware structure. Individual servers are manufactured in the form of “blades” (hence the name) which can be inserted straight into one central case (chassis) that can normally hold 8 to 16 of them. The chassis provides the individual blades with power, cooling, network interface, and interconnection with other blades using Ethernet, and it can also include a switch. What are the main advantages of blade servers? Particularly space saving in the data centre, energy saving, and reduction in the cabling necessary. Based on flexibility and easy expandability, they also provide server consolidation, which is essentially a combination of several servers in a single high-performance machine. An example of a blade server solution is HPE BladeSystem c7000.

Cloud computing

Cloud computing is currently one of the most frequently discussed concepts in the provision of IT services. It is a breakthrough technology that saves your financial costs by sharing hardware and software resources. Cloud computing offers computer technology as a highly variable service that you can adapt to suit your wishes and requirements. What do the concepts of “sharing resources” and “variability” mean? The load on the servers that your applications or services run on is, in most cases, much lower than the power that the server is able to provide. Such a server “slacks off”, consuming your money. Using a cloud solution, you can set how much power you really need, so you don’t have to pay for an “idle” server.

A similar example from everyday life:

“Imagine that you love beer, and on hot summer days you need to drink five beers a day. However, you won’t buy a brewery capable of producing hundreds of litres of beer, but you’ll go to the pub next to the brewery. In winter, your need to drink beer is not as strong, so you only have two beers a day. In this case, variability means that you decide how many beers you feel like having, and how many you pay for (you don’t have to sponsor the operation of the whole brewery). Breweries also share resources, because they make beer for many other thirsty people.”

In addition to investment savings, cloud computing also brings benefits in the form of easy administration and system maintenance, not to mention the speed and easy use of new IT solutions. The easy administration of any cloud solution is based on the fact that it is purchased as a variable service, not as a single product.

CPU

The central processing unit, or microprocessor, is one of the basic computer components. As the brain controls the body, the CPU controls the entire computer, and performs all calculations needed to run the tasks.

Failover

A feature that enables automatic switching of the running system to its redundant parts, ensuring continuous operation without any loss, even in the event of failure of the previously used system part. In practice, it means that if any piece of the provider’s hardware, for any reason, fails to work, the customer’s system is still fully functional. In addition, the customer won’t know what has happened, and everything will be taken care of by the provider, as the administrator of the entire system.

Firmware

The software part of the device which is closely connected with the hardware and which cannot be used separately. It can be compared to a system used by a company without depending on the services provided. The system allows the company to operate, it can be improved, if necessary, thereby increasing performance without changing the services provided. In this example, the services provided mean the applications running on the hardware served by the firmware.

HPE 3PAR Utility Storage

Last year, Hewlett-Packard Enterprise fought a tough duel with one of its competitors, Dell, about the company 3PAR, which was at that time the leader among manufacturers of systems and software for data storage. The significance of this company is also shown by the fact that HPE was willing to pay 2.35 billion USD for it. The aim of this huge investment was to develop a new generation of storage, HPE 3PAR Utility Storage, capable of delivering agile and efficient storage for virtual and cloud data centres. Instant scalability and adaptation enable the monitoring of your changing needs not only quickly, but also efficiently with regard to costs. What are the main benefits and basic features of HPE 3PAR Utility Storage?

• ● autonomic tiering technology (see multi-tier storage) balances costs and performance in providing a certain level of services in order to minimize costs
• ● autonomic provisioning and management simplifies and accelerates common storage administration, while reducing the likelihood of human error
• ● software products reduce manual administration by autonomic monitoring of performance and capacity utilization

• ● HPE 3PAR storage systems are designed to provide efficient support for multiple “tenants” in real time, i.e. different groups of users from different departments or companies use common storage
• ● the storage architecture is able to provide excellent service levels, utilization of high capacity, and efficient operation, maintaining the support of multi-tenancy

• ● HPE 3PAR storage is not only designed to be energy efficient, but also to be power efficient
• ● HPE guarantees a reduction in required storage capacity by up to 50% and more in order to meet your needs

HDD

HDD (Hard Disk Drive) is a device used for permanent storage of large amounts of data. It is a basic component of every computer. Hard disk drives that are currently on the market have capacity of several terabytes (TB).

HPE CloudSystem

The HPE CloudSystem solution is a complete hardware and software environment for providing cloud services. It is composed of several crucial building blocks: HPE BladeSystem, HPE Matrix Operating Environment, HPE Cloud Service Automation, and HPE 3PAR Utility Storage. The Operation Orchestration product for the total solution automation represents the software extension. With this tool, it is possible to significantly optimize repetitive tasks and prevent human errors. Based on this converged platform, and using provisioning and modification of complex infrastructure systems, you can quickly adapt dynamically changing IT requirements and needs in a matter of minutes.

Hybrid cloud

The hybrid cloud system is a combination of the above mentioned private and public clouds. This type of cloud is advantageous for those who want to enjoy the benefits of the public cloud, while keeping their sensitive data under their administration. In other words, in the hybrid cloud model, you only purchase the required services, but all your data will be stored in your traditional data centre. Another advantage of the hybrid cloud is the possibility to use your own IT resources and only access the cloud in cases of large load or overload, thereby eliminating the need to upgrade your IT infrastructure.

IaaS

Infrastructure as a Service – Infrastructure as a Service is a cloud computing distribution model. It allows the customer to pay for the use of the provider’s information technology like for phone services. The customer usually pays for the amount of data stored or CPU time used. Therefore, in this business model, you don’t have to invest in your own large-scale infrastructure, but you can take advantage of the Pay-As-You-Go model. The user only pays for performance actually used within the provider’s infrastructure. This type of service is useful wherever it is necessary to dynamically respond to requests from users.

IPv6

Internet Protocol Version 6 is currently a hot topic. It has been developed to replace the most frequently used IPv4 whose addressing options are becoming slowly but surely exhausted. In order to directly communicate on the Internet, any device needs to be assigned its own unique public IP address. Due to the fact that the allocation of public addresses to providers was associated with extensive wastage in the past, address space provided by the Internet Protocol version 4 is becoming insufficient. Given the speed with which the current Internet world is expanding, the higher version of the protocol will be necessary in all areas. IPv6 provides much larger address space, and is able to meet the needs of public IP addresses for all devices that can be connected to the Internet.

IPS

Currently, more and more Internet servers and services are being attacked. A specific feature of these attacks is the fact that malicious activity is performed before the attack itself to detect weak places and places that are not sufficiently secured. Therefore, Intrusion Prevention Systems (IPS) are being developed in order to prevent such attacks. The aim of the IPS is to identify malicious activity, record information about its progress, block the activity, and subsequently report it. Reported data is sent to the research team responsible for creating security rules and the database of suspicious IP addresses. An example of an intelligent IPS solution is MicroTrend TippingPoint.

Data migration

Data migration is a process of moving data between different storage locations, or even between different systems. The P2V migration, involving the transfer of physical servers into virtual environments, represents an integral part. The P2V migration type is suitable wherever the customer needs to renovate the physical environment due to outdated infrastructure, and is considering the possibility of using one of the cloud services providers.

Multi-tier storage

Multi-tier storage is an intelligent system for storing user data utilizing the benefits of various technologies. The storage system is usually divided into three tiers, each tier containing data used in different ways. In short, an intelligent storage system monitors the individual data usage frequency, and then automatically moves the data between the tiers. The most frequently used data must be readily accessible, so it is stored in the fastest and the most expensive tier 1, which is mostly based on SSD technology. The second tier, built mostly of standard high-RPM SATA hard drives, is used for less frequently used data. The least frequently used data is stored in the last, third tier, which is composed of low-cost conventional SATA hard drives, such as those used in standard desktop computers.

PaaS

Platform as a Service – Within the PaaS model, the provider provides comprehensive resources to support the entire life cycle of creating and delivering web applications and services fully available on the Internet, without the possibility of downloading software.

A typical representative of such a platform is, for example, an environment for running Internet applications consisting of several web and database servers. In such a case, users don’t have to worry about the security of servers and application environments: they can just use them to run their own applications. Therefore, there are no operational costs of administering such a solution, and users can fully focus on their projects.

Private cloud

The private cloud is a cloud only operated for one organization. It is operated either by the organization itself or by another party.

RAM

The English abbreviation RAM (Random Access Memory) often refers to the operating memory used by the brain of the computer (CPU) for temporary storage of currently processed data. Generally, the more data computer processes, the more RAM it needs for its work.

SaaS

System as a Service – In this case, an application is licensed as a service rented to users. Users buy access to the application, not the application itself. SaaS is ideal for those who just need standard application software, and require access from anywhere at any time.

IT departments are currently being forced to cut costs. If a company uses a standardized solution, it is often more advantageous to rent such a program as a service. A company email solution is a typical example. The customer doesn’t need to invest in its own hardware, buy licences for the operating system and other software, and incur significant costs of operational activities associated with the operation of such applications. The customer needs to have its system available at any time and anywhere. In such a case, the provider is responsible for the complete life cycle of the program, from its installation and administration to various security updates. The user only uses the program itself without having to be involved in its administration in any way, which significantly reduces its administration costs.

Storage

The term “storage” refers to the device that is used to store your data. The data storage device may consist of multiple types of memory devices that use different data storage technology.

Data encryption

Data encryption is a type of cryptography that protects electronic data from unauthorized access, allowing the owner to protect its privacy.

Scalability

Scalability is a much desired feature of any system. It allows you to respond to necessary changes, simply by extending the system without the need of replacement.

TippingPoint

TippingPoint is a hardware element ensuring the security of a cloud system. This element is able to analyze incoming data traffic and search the traffic for attempts to identify weak parts of the system and break the security of your services. MicroTrend has been developing intelligent TippingPoint elements, ensuring the security of your cloud solutions, for many years. An example of a currently available cutting-edge product is MicroTrend TippingPoint.

Traffic

The term “traffic” refers to the average network load (speed) at a specific time.

Public cloud

The public cloud is sometimes referred to as the classic model of the cloud. The cloud service provider owns high hardware performance that is distributed to individual customers by creating individual virtual machines. Unlike the private cloud, it is not designed for a single entity (e.g. a company), but individual virtualized servers are sold to end customers.

Virtualization

Virtualization means simulation of a different physical environment than the one that is available. Using virtualization, it is, for example, possible to play games from the old TV console on a modern computer, i.e. run a program on hardware that is not supported as such. Virtualization also allows you to run multiple processes simultaneously. It is possible to run multiple virtual computers on one piece of physical hardware. The user doesn’t know that the device is not physical, but virtual. In addition, the solution also delivers significant cost savings, because it is not necessary to buy, power, and maintain more than one device. Its purchase and operating cost is higher than the price of one standard machine, but considering the fact that all you need is just one device, it is clear that the cost reduction will be achieved. Virtual servers that run on the newly acquired equipment can be used by many different persons, so costs can be shared. In this way, you can resell currently unused performance.

Virtual server

Virtualized hardware tailored to suit the customer’s needs. This is not a physical machine, but a virtual server that, in fact, works on the hardware allotted by the provider which can’t be seen by the end user. Everything looks like a standard server.

vMotion

vMotion is one of the sophisticated features of the VMware product. It allows you to move your virtual server from one physical server to another without impacting the end user. vMotion keeps the IT resources used in operation at all times, thereby providing flexibility and availability to meet your growing requirements. What does vMotion bring to the user? In particular, it allows you to reduce the time of the system failure, which results in improved reliability and continuity of services provided. It also reduces IT costs, based on the flexibility in server consolidation. vMotion also increases energy efficiency in providing the same services on fewer servers through dynamic deactivation of unused servers.

VMware

VMware is software that allows you to run multiple virtual computers on one computer simultaneously. With VMware, you can run different systems, from conventional computers for everyday work and administration, to web and database servers. Thanks to its cutting-edge product, the company VMware is considered the world’s leader in virtualization. Satisfied customers who use VMware solutions include many major international companies such as Volvo, Ernst & Young, and American Express.

High availability

High availability of cloud services is based on the way services are implemented. In the event of a technical failure, the faulty hardware is replaced with redundant hardware, intended for this purpose, with minimal delay. The cloud service provides the user with 100% service availability, even in the event of hardware failure. Moreover, the user doesn’t notice any failure, and there is no loss of data or performance.

Web 2.0

Web 2.0 is a term that was introduced in 2004, and that refers to the second generation of the World Wide Web development. 2.0 is a designation taken from the software industry, where it indicates new versions of programs (based on incremental numbers). Just as software, the new generation of the Web includes new features and functionality not previously available. However, the concept of Web 2.0 captures a series of technological improvements rather than a new version of the Web. Examples of new features or parts of Web 2.0 include blogs (websites with users’ posts), Wiki servers (websites such as Wikipedia, an Internet encyclopedia edited by users from all around the world), social sites (e.g. Facebook or MySpace, where users communicate with their friends), or a variety of web applications executable directly in the web browser. Web 2.0 technologies provide a degree of interaction between the user and the Internet that was not previously available. Websites are becoming more dynamic, creating “online communities”, and facilitating information sharing on the Internet.
