Micro DC What is it?

    Introduction


    Since the topic of the clouds is very fashionable now, the relevance of the data center is also great. But if your enterprise size is average and there is no separate data center as unnecessary, then vendors can offer you


    1. Modular data center.
    2. Mini data center. (miniDC).

    Strictly speaking, we will dwell on the latter. The name is very beautiful. But actually you probably already have it. If not, then you can do it.



    What is it?


    The proposed solutions in reality are a 19 "server cabinet with mounted inwards:


    1. Server (or several).
    2. Network devices (switches and routers)
    3. UPS
    4. Organizers, patch panels, fans, power panels.
    5. Monitoring system.
    6. Service contract.

    Everything except point 6 is quite obvious. Under a service contract, everything becomes clear, given two circumstances. The warranty periods for all components are different, when buying a contract, a guarantee is given for everything for the duration of the contract. That is, with a 3-year contract, the fact that the UPS in practice have a guarantee of 2 years from the moment of release, and fans 12 months, does not play a role. The second important aspect is that no manufacturer makes all the components himself, except for their products there are ODM assemblies and with guarantee their internal squabbles.


    Of the advantages of this approach. On the site, choose a set of "offal" and the conditions of the guarantee. Get ready to connect the cabinet assembly. The minus is obvious. Price. Self-collection will get cheaper.


    If assembled by yourself.


    Remember the ultimate goal first. You will deploy a virtual infrastructure as in a large data center. Even a private cloud (in practice - rather a hybrid).


    1. Server (s) think clearly. Good white is really better. But you need to understand them well. Of course, take the HDD hot-plug to the reserve and the second PSU. He is also a hot-plug. IPMI is a must.
    2. Network hardware. Every man to his own taste. Take on tasks.
    3. UPS Online is certainly better, but it is more complicated and more expensive than line-interactive. In general, the UPS does not protect against shutdown, there is enough time to correctly stop or start the generator. Online isolates from the network, if it is not so hot, then the server is somewhat more expensive than the difference in price of different UPSs. I write with blood, it’s not the server that burned out, but the VoIP-PSTN gateway, but it arrived only after two weeks.
    4. Cupboard. From experience, I’ll say that it’s better to touch with your hands, and then 60x80 cm in practice 60x74-76 can easily turn out to be, and the server 74, and also the network plugs ... In short, there is no aesthetic appearance without the back panel and the fans are audible. The same applies to panels, organizers, fans, and more.
    5. In general, it is necessary to monitor all devices, but here everything is individual.
    6. A pack of warranty cards or copies of purchase documents.

    Of the advantages of this option is the price and exact compliance with the tasks / opportunities.
    Of the minuses. Quite a laborious task requiring skill and time.


    In operation, such a self-assembly is definitely no worse than a miniDC from the manufacturer. More fuss with a guarantee.


    conclusions


    It’s clear that miniDC is just a beautiful name for a widely used solution. I intentionally did not mention vendors. The article is not advertising, but Google knows everything. Let's say there is a cabinet made under the office for outerwear. Until you open no sound is heard. Find out the price ($ 10K- $ 15K) sounds can not be heard from you. It’s just that if at this stage the IT service takes the task seriously, it will definitely have more time to watch films, self-education, discuss sports results, TV shows, gossip and other components of IT culture.


    UPD According to the comments. mini, micro Datacenter - really a 19 "rack with equipment to choose from.
