ReadyBOOT
ReadyBOOT - Diskless booting solution IT Managers Main Headaches 1. Cost, time, human resource for maintaining multiple computers. 2 2. Recovery cost for missing or corrupted data. 3. Legal issue caused by using illegal license. 4. Virus, Malware and Trojans. 5. Security concern. What is a ReadyBOOT? Diskless Client Legacy personal computer without HDD and operating system. Pull the OS booting image from server when turned on. Pull an application image from the server and run the apps on client using clients CPU, memory, and graphic. The Server (ReadyNAS with ReadyBOOT server software) Connected on Gigabit or 10G network with SSD built in. iSCSi file transfer between server and client. Keeps Clients OS booting data and Application as an image file. Provides user data storage. ReadyBOOT OS Boot IMG Applications Gigabit Switch Client 3 No HDD User data ReadyNAS 516 Requirements for ReadyBOOT • Gigabit network Gigabit NICs on client Gigabit managed switches ( better to have 10G uplink) • Servers ReadyBOOT Server S/W (Free bundle from NETGEAR) RAM required at least 16GB to server over 50 clients SSD drive for fast IO (RAID configuration) Usually two ReadyNAS required per site for redundancy Server NIC teaming will be required for better performance – Prevent network bottleneck • Clients Client license ( Approx. $50 per client ????) PC BIOS menu should be supported ‘Network Boot’ option. Better to have Wake on LAN (WOL) 4 ReadyBOOT Topology ReadyBOOT Server ReadyNAS-01 Internet ReadyNAS-02 OS Boot IMG OS Boot IMG Applications Applications User data User data 서버이중화 (Fail Over / Load Balancing) Router Gigabit Switch PC001 5 PC002 PC003 PC004 PC005 How to setup ReadyBOOT 2 1 Install Master OS/Applications Upload image to server OS Boot IMG Applications OS/APP IMGs User data OS/APP IMGs ReadyBOOT Server Rapid client deployment 3 6 Remove HDD then change boot order to ‘network boot’ in PC BIOS menu. ReadyBOOT Configuration ReadyBOOT software When boot client receives OS boot IMG from the Server via Network Pull applications from Server Run Application using clients CPU, RAM, and graphic. Store user data on server. OS Boot IMG Applications 3 x SSD for OS, App User data ReadyNAS Gigabit Switch CPU Memory VGA No HDD ReadyBOOT is ALL-IN-ONE Solution. All functions integrated for network booting service (DHCP, gPXE, TFTP, iSCSI Target) iSCSI traffic Clients 7 OS, Application image stored in SSD volume. Advantage of ReadyBOOT Solution 8 Ease of Management Having each user utilize the same image--the operating system as well as the installed applications--reduces administrative and support costs. Administrator Centralized Client OS Management OS Boot IMG Rapid Client Deployment Applications Only Server admin have User data permission to change the settings. Client can’t Smart Client Server ReadyNAS 516 access the server software. Share Single OS Image 9 Install O/S, applications, patches, All clients benefit from it. Security – Viruses, and Trojans Gone After reboot the client, the system will be restored to a clean state without any Viruses, Malware and Trojans. Reboot Clean OS Only Administrator can modify O/S and Application image data with special authority. If client download virus infected file from internet, it will be saved onto the data storage part of the server. Virus will NOT be activated. 10 Performance improvement Boot up time comparison More than 45 seconds Booting Win 7 with SATA 7200RPM Drive About 25 seconds Booting Win 7 with SSD Drive About 25 to 30 seconds Booting Win 7 on Diskless Client with SCS Diskless client shows almost same booting speed with SSD Drive. It read/write via network so there is no HDD I/O delay. 11 Green - Hard Disk Expenses and Electricity bill Saved Spinning hard disk drives are the most common source of failure in computing devices today. Without them, the shelf-life of a computing device increases considerably. Many diskless workstations are self-cooling, they don’t require a spinning fan to keep the temperature down inside the device. Without any moving parts diskless workstations are known for significantly outlasting the shelf life of PCs. 12 Do not need HDD on clients. Quiet Operation System Temperature down Smaller electric bill ReadyBOOT Server Admin GUI 13 Admin Web GUI All configuration can be done on Web GUI 14 Admin Web GUI All configuration can be done on Web GUI 15 16 17 Comparison Charts 18 VDI vs. SCS VDI Initial Introduction Costs • VDI will requires a major investment in server hardware, and SCS • possibly in storage and network infrastructure. The total cost of the server hardware, storage, and network equipment might exceed that of procuring a basic PC for each user. • It may also needs additional Thin or Zero clients. • Graphics intensive desktops / applications may require All services can be operated by Single ReadyNAS. • ALL-IN-ONE Solution • Continue to use existing PC • No performance reduction or specific remoting protocols and increased expense. This also affects video collaboration tools. Server loads and Performance • There will be heavy lords on Server because many of VM are use central server resource. • heavy loads on the Server Document working will be not a problem but when the VMs because all process use client’s play multi-media or doing video rendering then performance own resource. reduction will be occurred. • Historically, some VDI performance has been slower and • impersonal resulting in poor user experience. • improvement of client’s booting and process operating speed Poor performance if solution (stack) not well designed to user need and for efficiency. Usability and Maintenance 19 • IT manager will need a 3rd party tool for updates security • It shares single OS Image so updates patch or installing software for each VMs. only one image and then all Clients • Printing often requires a 3rd party add-on PC will be updated. • Scanning is not natively supported • Bi-Directional Audio is not natively supported • Display protocols not suitable for Graphics Design • You can use the PC like a general desktop PC.
