GCafe Manual GCafe Diskless is a new feature from version 2.0.0.0 of of GCafe GCafe ● In version 2.0.0.0 GCafe Version 3 includes 3 soware together: ○ GCafe: GCafe manages and updates the game automacally. (Can be installed in the machine room with or without a drive hard). ○ Net Disk: A connector to the GCafe server to map the server game drive to the virtual drive client. Net Disk can be called Game Server ○ Diskless: A desktop hard disk manager. The workstaon boots the operang system from Diskless Server can therefore call Diskless Server as Bootrom Server. ● To install GCafe Diskless must install all three programs. Can install each software on each server and configure The images for these programs combine with each other (via IP) to form an operational entity Is for the workstation but it is better to install the same server to save money and management Easier. ● All of of these these programs work on Microso's Windows pla orm. orm. For GCafe Client Version 2.0.0.0 installed for the hard drive room can run on Windows XP or Windows 7. For the system GCafe Diskless Server should use Windows Server to optimize all the resources of of the the Server such as 8GB of of RAM, RAM, SSD ... besides, Windows Server will be stable so that GCafe Diskless system will be stable and stable higher efficiency. PART II: STEPS OF PREPARATION ● PREPARATION FOR SERVER: ○ Hardware: Mainboard must support Sata 3 RAM as required, minimum 8GB The CPU selects the right type for the motherboard, without the high processing speed. Network card: Depending on the needs, at least 2 network cards. Requires LAN 1000Gb SSD: Must have SSD (running on Sata port 3) for Cache and Writeback. HDD: Just one HDD to install OS for Server and Game. Recommend new HDD stability peak. ○ Soware: Should use Windows Server 2008 R2. (Do not use Windows 2008 Server) Windows Server 2008 R2 with TRIM support makes SSD work better. Using 32bit or 64bit Windows Server 2008 R2 is fine. ○ Format parons: HDD: Divide C: from 15 to 30GB containing the server operating system. Cluster as high as possible HDD: Chia E: is the rest to store game. Cluster should format 64K to workstation Mount faster and load faster on the OS. SSD: Divide D: 35GB minimum to contain Image. Cluster should be 64K format for the reader to read And load Image faster. Finished ‐ Rach Gia 28/9/2012 SSD: Split F: is the rest to do cache and writeback. Cluster should be 4K format to weather Save storage space. (Size on disk) ● MACHINE PREPARATION: ○ Hardware: Must have a hard disk drive to install OS and upload Imgae to Diskless server. Once created By Image, the workstation does not need HDD. Recommended 1000Gb network card. 100Gb network card loaded into slow OS but load game Relatively fast. Workstation network card must have bootrom to boot the operating system over the network. Most of of the the The onboard network card already has bootrom. Need to enable bootrom of of the the onboard network card to Boot the operating system over the network. If If the the onboard network card does not qualify for 1000Gb, then add a 1000Gb removable network card Need to choose bootrom type. Note if if using using bootrom from the network card to disable the card disable
Onboard network. Also note that some removable network cards have incompatible bootrom With some mainboards. Prioritize the Atheros network card. Experience shows that Atheros network cards load The operating system is very fast. Realtek or Intel new network cards load the kernel Onions are relatively fast but not Atheros. Old Marvell or Nvidia network cards almost never work with GCafe Diskless or manually update the driver to work. Soware: Workers can use 32‐bit Windows XP 32bit or Windows 7. Note: GCafe client does not install on 64bit OS. The partition containing the OS is forced to NTFS format. ● NETWORK PREPARATION: ○ Switch: It is recommended to use 1000Gb for all ports ○ Network cable: CAT5e cable can be used. Game room with multiple machines should use CAT6 cable. If If right right Cable CAT5e, the cables between switches should use CAT6 cable. The cable from the Server to Switch should also use CAT6 cable. ○ Network switch: good to use. Experience has shown that if if you you use a poorly equipped cable Can operate 100Mb. At the beginning of of the the press should also use a good click type. Experience shows If If the the bad press can damage the head, resulting in poor contact also makes the cable Works 100Mb. ○ For the machine room has many machines when the network infrastructure need to connect the star switch. That means there must be a main switch divided into sub switches. The server must go into the main switch. Job This makes the server able to balance the load in the network while the workstations have paths No more than 2 switches. Choose the best type of of switch switch to ensure better switching, tape No obstruction. ○

SECTION IV: BACKUP THE NAME AND IP FOR THE CARD SERVER ● For the server system has many network cards, the idenficaon of each network card and provincial IP se ngs for Every network card is a must to make it easy to manage and troubleshoot later. ● For Server have two network cards: Should select the onboard network card as the main network card Diskless. Network card The rest for GCafe and Net Disk running together. ○ For example Network card 1: Named Diskless. IP: 192.168.1.200 Network card 2: Name the GCafe_NetDisk. IP: 192.168.1.201 ● For Server has three network cards: Should select the onboard network card as the main network card Diskless. The card The other network is assigned to GCafe and Net Disk ○ Example: Network card 1: Named Diskless. IP: 192.168.1.200 Network card 2: Name the GCafe. IP: 192.168.1.201 Network Card 3: Named Net Disk. IP: 192.168.1.202 ● For Server has 4 network cards: Should select the onboard network card as the main network card for Diskless. The card Remaining networks are assigned to GCafe, Net Disk and Diskless_02 ○ Example: Network card 1: Name Diskless_01. IP: 192.168.1.200 Finished ‐ Rach Gia 28/9/2012 Network card 2: Name the GCafe. IP: 192.168.1.201 Network Card 3: Named Net Disk. IP: 192.168.1.202 Network card 4: Name Diskless_02. IP: 192.168.1.203 ● This division is very useful for installing 3 programs of GCafe Diskless. Help us press Determine which IP is running for which service, so that when something goes wrong, we can easily identify and fix it Restore by replacing and reassigning the IP is complete. ● Although network cards have been assigned and run for each service, we sll take advantage of all the cards
Network in the server to load Diskless. That is, each network card, will run 2 services: 1 service The key is fixed and a secondary service is load‐balanced for diskless. The figure below shows the selection of network cards available on the server for load balancing for diskless. Doing Load balancing, the workstation in the network when boot up will be divided load for the network card to reduce Bandwidth congestion from the server.

Machine suffers Removing the MAC when booting up will show the registration table as shown above. ● For beginners, the bootrom can read and follow the order from beginning to end Self ‐healing GCafe Diskless. As soon as you get used to it may not be in any order, however The process should be adhered to to minimize the occurrence of the problem. 8. ADDITIONAL EXPLANATION ABOUT CACHE, WRITEBACK AND WAY SET UP ● For bootrom or game server systems we have the concept of cache and writeback. This secon only Explain the meaning of these concepts in GCafe Diskless.
Cache: Can use RAM and use SSD to set. In the setup Gcafe connection Net Disk has Select the RAM to cache and select the SSD to cache. For example, when setting up 5GB of RAM as a cache And choose F: to cache Game Disk: When the client accesses the game from the virtual drive, the server will read This game data once and put up the cache. If the RAM is free, then RAM will be the same When there are more games required from the workstation, the server will (read one game at a time) and put up SHADY. Until the cache data exceeds 5GB, the server writes the cache to the SSD. If the SSD continues The server will automatically clear the cache of previous games. Note when server accesses The cache on the RAM will be faster on the SSD. Because the game is saved and accessed on the server's cache Speed of access from the workstation will be met in time to make the game faster than Run on HDD. For example: When the server boots into the OS, the first client loads the Punch game, the machine
Finished ‐ Rach Gia 28/9/2012 The host will read from the game hard disk to put on cache and distributed to the workstation. When there is another machine Hit Counter game server is not read from the HDD anymore but will read from the cache to distribute to Workstation should load speed Game Counter of the second time machine will be faster than the machine access So Slip on Diskless GCafe will load faster than HDD. ○ Writeback: can use RAM and use SSD to set up. Diskless has cache sengs for Image And choose SSD to do Writeback. For example, set the cache for Image to 2GB and choose Writeback as F. 2GB This means that the workstation is allowed to retrieve data from outside to a maximum of 2GB. If the machine If the external data retrieval station exceeds 2GB, the program will write the excess data Writeback. When the workstation resets or shuts down, Writeback will automatically delete. It can be said that the cache Image and Writeback are temporary storage for what the workstation retrieves from the outside. Note : If Writeback full then workstation will not load Image from Gcafe Diskless. ○ Set cache and writeback: Depending on the amount of RAM that is configured accordingly. Temporary there Can be set by the following formula:
Total RAM ‐ 2GB (System) ‐ 2 GB (Image) = Rest for Game Disk. If 8GB of RAM ‐ 2GB of system left over 6 GB. 6GB continues to set 2GB for the remaining 4 GB This 4GB set up for Game Disk. ○ For GCafe Diskless systems, cache and writeback are the decisive factors for RAM and more The better. In addition to distributing caches to workstations faster, more network cards are needed. Network infrastructure must meet standards. ○ For diskless workstaons, fast or slow OS loading is no longer dependent on the speed of the HDD As before, depending on the available network card, depending on the image access speed from the server. Should choose the new network cards support 1000MB for workstations and Image on the server should For storage on SDD ‐ 64Kb cluster format.
