Maria is a 23-year-old female business graduate who recently completed a graphic design program in New York. While she has received some job offers, she is concerned that companies prefer cheaper interns and that her university did not adequately prepare her for the job search. She feels pressure to find meaningful work but lacks confidence in existing job hunting sites and fears settling for a job that does not fulfill her.
The document discusses how Branch Repeater technology works to optimize WAN communication. Branch Repeater uses TCP optimization techniques like selective acknowledgment, window scaling, and compression to improve throughput over the WAN. Delta compression analyzes changes between data streams to reduce the amount of data sent for frequently updated resources like desktops. This improves performance for common use cases like remote desktops and web access over the WAN.
Users need the ability to increase storage space available in oVirt storage data domains (ISCSI & FC) without increasing the number of LUNs presented to it.

In this session, we'll discuss new volume types in Red Hat Gluster Storage. We will talk about erasure codes and storage tiers, and how they can work together. Future directions will also be touched on, including rule based classifiers and data transformations.
You will learn about:
How erasure codes lower the cost of storage.
How to configure and manage an erasure coded volume.
How to tune Gluster and Linux to optimize erasure code performance.
Using erasure codes for archival workloads.
How to utilize an SSD inexpensively as a storage tier.
Gluster's erasure code and storage tiering design.

Решения КРОК для виртуализации и консолидации вычислительных и системных ресу...КРОК
Основная идея консолидации вычислительных ресурсов состоит в том, чтобы создать мощную централизованную систему обработки данных вместо разрозненного парка серверов.
Подробней о решение можно узнать на http://www.croc.ru/solution/ikt-infrastructure/it_infrastructure/virtualization/
This document discusses Citrix NetScaler and its features for application networking, delivery, and load balancing. It describes NetScaler's capabilities in areas like acceleration, security, availability, and offloading. It also provides examples of how NetScaler can optimize traffic and TCP connections between clients, servers, and applications to improve performance.
This document discusses Citrix XenDesktop and its components. XenDesktop provides virtual desktop infrastructure (VDI) as a service by hosting desktops and applications on centralized servers and delivering them to users on any device. It addresses issues like security, manageability and productivity through features such as profile management, streaming, and support for various hypervisors and devices. The document also outlines XenDesktop licensing options and new features in version 3 like HDX plug-and-play USB and smart card support.
The document discusses optimization of WAN connections between branch offices. It describes how Citrix WAN optimization technology works using TCP optimization and compression techniques like delta encoding to improve throughput over bandwidth-constrained WAN links. Specific techniques covered include TCP packet management, multi-level compression, delta compression between sites, and optimization of common protocols like CIFS. The goal of WAN optimization is to improve application performance across remote or mobile offices as if they were on a local network.
The document discusses the implementation of Citrix XenApp 4.5 at Uralsky Finansovy Dom bank. It provides information about the bank, goals of the implementation such as expanding the branch network and improving client service quality, the chosen solution of Citrix XenApp 4.5, and anticipated outcomes like opening new branches in Moscow and Perm region cities and reducing operating costs.
The document discusses Citrix NetScaler and its high availability capabilities for load balancing applications. It describes how NetScaler provides global load balancing, acceleration, security and availability features to optimize traffic and ensure access to applications. Key components mentioned include AppExpert for intelligent traffic management and policies, and various load balancing algorithms for distributing traffic across servers.

This document discusses Citrix XenDesktop and its components. XenDesktop provides virtual desktop infrastructure (VDI) as a service by brokering access to virtual desktops that are hosted on servers. It allows for centralized management of desktops and applications while improving security, flexibility and reducing costs compared to traditional PC deployment models. New features in XenDesktop 3 include support for USB devices, smart cards, improved media streaming and user profile roaming.
3. Что такое Inquisitor?
• Inquisitor — это платформа, которая умеет:
– Определять аппаратные компоненты (включая
серийные номера и версии прошивок).
– Тестировать компьютер — по частям и в целом.
– Вести учёт компьютеров, их частей и ситуаций, в
которые они попадают.
– Создавать интерфейсы взаимодействия с
пользователем и другими системами.
4. Несколько фактов
• Разрабатывается как производственная
система с 2004 года.
• Доступен как открытая платформа с 2007 года.
• Inquisitor распространяется свободно (GPLv3).
6. «Зачатие»
• Предпроектная подготовка: лабораторные
исследования, определение подходящих
под задачи компонентов, бенчмарковое
тестирование.
• Централизованное хранилище результатов
всех экспериментов и тестов.
7. Пример: USB-термометр
Разработан 16-канальный USB-
●
термометр, обеспечивающий
точность до 0.1°C, поддерживаемый
модулем мониторинга thermo.
Может использоваться для
•
сертификации, интегрального
мониторинга температур, научных
исследований и т.п.
8. «Рождение»: как это происходит?
• Вариант №1: сервер приехал от поставщика
– Доверяй, но проверяй!
– Возможны:
• Повреждения при транспортировке;
• Брак у поставщика;
– Хочется проверить сервер перед отправлением
«в бой»
9. «Рождение»: как это происходит?
• Вариант №2: полусамосборный сервер
– Часть комплектующих закуплена отдельно
(например, для обновления старого сервера)
• Вариант №3: самосборный сервер
– Все комплектующие закуплены отдельно, сервер
собирается «с нуля».
• Во всех случаях требуется тестирование.
10. «Жизнь»: введение в бой
• Инвентаризация — возможность в любой
момент времени сказать, где находится
каждый из серверов и из каких компонентов
он состоит.
• Необходим учёт серверов, компонент и их
движения.
12. «Смерть»
• Если какие-то компоненты (или весь сервер
целиком) починить невозможно, то нужно
корректно списать сервер и его компоненты.
• Возможно, некоторые из компонент поступят в
резерв запчастей, которые можно будет
использовать для реанимации других серверов.
