Server racks

My best friend Denis is an IT specialist in a big company and now he is preparing for an international IT conference on server racks construction. The conference is to be held next month and he has a deadline to prepare the speech on server racks requirements until the end of this month. That"s why I haven"t seen him for a long time as he is very busy. He will give a speech on the requirements for a server racks construction in medium-sized companies in our country. I wanted to help him but he said he was fine and he would do it on his own. But I really wanted to help so I called Denis and told him that I was going to visit him in the afternoon. Finally he said ok and I went to his house at five in the afternoon. He was really so busy that he didn"t even notice me in the racks. I called his name and then Denis noticed me. I asked him how the work on the requirements for a server racks construction in medium-sized companies was going and he told me he is still collecting materials about server racks requirements and he was reading a lot of publications about this subject. He told me that there are a lot of material available on the requirements for a server racks construction in medium-sized companies but it is very time-consuming to prepare the speech for the conference.
