Zamyšlení nad myšlením
Už jste se někdy podivili nad nedostatkem myšlení? Je to zvláštní, jak často přemýšlíme o tom, jak ostatní nepřemýšlí. Schopnost myslet předpokládáme u svých partnerů, kolegů, spolupracovníků, poradců nebo přátel. A přesto, zdá se, že docela často narážíme na zjevný nedostatek myšlení. Nebo snad lépe, na nedostatek kritického myšlení. Naopak se při hlubším pohledu, zdá být zcela překvapující, že tento atribut myšlení vůbec ještě někomu přiznáváme. A přesto, jedním z hlavních úkolů Vás, vedoucích, je nalézt cestu, jak přimět vaše podřízené se zamyslet, zpochybnit každodenní rutinu či navrhnout lepší a radostnější proces.

There are many reasons why implement VDI (Virtual Desktop Infrastructure) and easier Business Continuity Management is one of them. Virtual Desktop Infrastructure is an very old approach towards computing, you might recall old mainframe systems era, when users has been connecting to big mainframe systems using thin-clients and terminals. However back then, networks was slow, and users has been typically in a next room to a mainframe system or using dial-up connection to mainframe system and only text console commands.

Today, networks are fast and desktop PCs are very powerful, too powerful for most of a tasks we want them to do, so a lot of computing resources, storage and memory goes to waste. And that is why Desktop Virtualization got born. In an environment with virtualized desktop infrastructure, desktops are running virtualized in a datacenter and users are using just a thin clients to connect to their virtual instances in a datacenter over LAN, MAN and even WAN connection.

Users of different storage arrays often wonder how much usable capacity they get out of purchased amount of disk shelfs. For sure this is a key metric in ROI and TCO calculations, this information is also essential to implement proper capacity planning. In an ideal world, we would probably purchase usable disk capacity directly from vendor, however we do not live in a ideal world so we need to think while making our storage purchases. In this article we will show, how much usable storage capacity we can get from physical disks with NetApp disk arrays, where are hiding overheads and how to influence these overheads.
