Exploring the Insides of the Huawei RH5885 V3 Server (unboxing)

    Hello! Today we’ll go down from the clouds to the earth, talk about the glands and see what is and how it is arranged inside the server Huawei Tecal RH5885H V3 .

    It is on this model of servers that the CloudLITE.ru IaaS service virtualization cluster is deployed . Recall that on the same servers we have a hypervisor and a distributed virtual storage VMware VSAN.

    Before we go directly to unboxing, a few words about why you chose this particular model. No, it's not about Asian import substitution :).

    1. In our virtualization clusters, we use 4-socket servers, since they allow you to allocate more cores to 1 virtual machine. This server satisfies this parameter.

    2. The server was needed for a specific architecture using the VSAN solution. As we mentioned in a previous post , VMware has a list of compatible hardware suitable for building virtual storage. Among this selection of 4-socket servers we need, there are not so many.

    3. This model, unlike the analogues available on the Russian market, runs on Intel Xeon E 7 series processors.

    4. The cluster configuration implied the presence of 24 disks on one server. This model just allows you to create three disk groups, each of which will have 7 hard drives and 1 SSD (in our case, PCIe flash cards take their place).

    5. Finally, the price-quality ratio. It is clear that all 4-socket servers are enterprise solutions that come at a price. But on the market, even in this segment, there are models priced higher or lower. The selected model just gives a large number of opportunities, but at a lower cost.

    6. And he is with light green accents (our corporate color), and here we could not resist :).

    So let's get started.

    In the photo below we see a well-designed and neatly designed ventilation system with front access and filters.

    Fans can be changed "to hot." So that during the repair work the cold air “does not leak” through the empty hole, a plug is provided in each module, which prevents stray air exchange.

    Now let's go inside. Thanks to the modular structure, the server is disassembled without any tools. What pleased me most was the most detailed and very intuitive diagrams for assembling / disassembling server modules: everywhere there are explanations of how and what to grab onto, marking of server components (disk modules, processors, etc.). In general, you will not get lost.

    On the right are two expansion modules for installing PCIe cards.

    Our configuration uses 4 PCIe cards - 3 PCIe SSD ES3000 and 1 PCIe Ethernet adapter. The CN21ITGAA000 interface board is based on Intel 82599 and has 2 x 10G external network interfaces. Another 2 x 10G adapter is integrated on the motherboard.

    Move on. In the middle is a compartment with 4 Intel Xeon E7-4830 v2 processors. On the left is a compartment with memory cards and installed RDIMMs.

    We are going to install. At this stage, everything went without much difficulty. The only thing that caused questions in the server device was the complete slide. It could be done more conveniently.

    To manage the server and maintain it, all standard technologies are available today - BMC, IPMI, SOL, KVM over IP and VirtualMedia.

    Access to the service processor is also carried out through the touch panel. With its help, you can set the necessary settings of the service processor, check the status of all server components and even play Tetris .

    View from the side of the hot corridor: power from different beams is connected to two PSUs, which are reserved and allow hot-swapping.

    That's all. What can we say based on the results of 6 months of operation: the servers are stable and do not cause any problems with operation and maintenance. Isn't this the most important thing in hardware?

    PS: from next week we will temporarily suspend free test access to CloudLITE.ru (there are a lot of people who want it), but until the end of the week you can still register and get a test until the end of June 1 vCPU, 1 GB RAM, 50 GB HDD. Hurry up!
