  • Tape vs SSDs backups regarding long-term storage reliability

    - by user66131
    My question is very specifically about solid state drives, not regular hard drives. I would like to put in place a grandfather-father-son backup scheme, with the SSDs being used for the grandfather and father portions, and the yearly grandfather would be locked in a safe offsite for maybe 5-10 years. Can I expect that after this period of time the data would be preserved as well as it would be on a tape?

  • Internet Troubles - PPPoE vs PPPoA?

    - by AkkA
    I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

  • Amazon EC2- many micro-instances vs single small/medium instance

    - by shashankaholic
    I have a chat application using stack of Openfire, Tomcat6 and MySQL. Currently, i have installed all these servers on single Linux micro-instance(613 MB memory). Even in low user base 10-20 i am encountering CPU overload which is quite obvious here. As, i am new to Amazon EC2 can somebody suggest me how to scale up my architecture according to traffic use? should i use separate micro instances for every app server(openfire,mysql,tomcat6) should i use single small or medium instance for whole server stack. Some factors in context: high reliance on MYSQL high memory usage due to file transfer web-application interacting with other Amazon service like S3,SES

  • Nginx vs Apache as reverse proxy, which one to choose

    - by mhd
    Hi, this kind of question maybe has been asked here but I couldn't find any that really match my question. Heard that nginx performance is quite impressive, but Apache has more docs, community(read:expert) to get help Now what I want to know, how both web servers compare in term of performance, easiness of config, level of customization,etc. AS REVERSE PROXY server in a vps environment?? I'm still weighing between the two for a ruby web app(not ROR) served with thin server. Specific answer will be much appreciated. General answer not touching the ruby part is okay. I'm still noob in web server administration.

  • Windows Server vs Sharing

    - by Mark Lawrence
    Not sure if this is the right place for this question. I have a friend that owns a small business running 3 local machines, that are connected to the internet, and a server that each local machine connects to. He has recently bought a newer server, and by server I mean a Windows Vista box. He wants to use this purely to store data that the 3 local machines can access, kind of like a glorified external hard drive. Im suggesting to fore-go the server option and simply setup sharing on the 'server' box. Interested in hearing any suggestions as to whether the server idea is preferable?

  • Preventing SSH RSA host key warnings for change of key vs IP address

    - by Adam M-W
    I have a network with DHCP enabled, and also a computer that dual boots operating systems and has different SSH keys on each (and yes, I would like to keep different keys on each rather than copying the same identity/private key to each). Because the IP address does not change between operating systems because the MAC address is the same, when connecting to ssh, even when not using the IP address but the hostname via DNS/mDNS, I get the warning: Warning: the RSA host key for 'hostname' differs from the key for the IP address '192.168.1.172' Offending key for IP in /Users/user/.ssh/known_hosts:37 Matching host key in /Users/user/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? How can I surpress the warning when the hostname differs from the IP address for that hostname, but retain the ability to check host keys are the same for each hostname? (each OS has a unique hostname)

  • Multiple servers vs 1 big server performace

    - by pistacchio
    Hi to all! My team of developers has suggested a server structure for an upcoming project we are developing. Our structure is "logical", meaning that the various logical components of the application (it is a distributed one) relies on different servers. Some components are more critical than others and will be subjected to more load. Our proposal was to have 1 server per component but the hardware guys suggested to replace the various machines with a single, bigger one with virtual servers. They're gonna use Blade Servers. Now, I'm not an expert at all, but my question to the guys was: so if we need, for example, 3 2GHz CPU / 2GB RAM machines and you give me 1 machine with 3 2GHz CPUs and 6 GB of RAM it is the same? They told me it is. Is this accurate? What are the advantages or disadvantages of both the solutions? What are the generally accepted best practices? Could you point out some URL reference dealing with the problem? Thank you in advance! EDIT: Some more info. The (internet / intranet) application is already layered. We have some servers on the DMZ that will expose pages to the internet and the databases are on their own machines. What we want to split (and they want to join) are some webservers that mainly expose webservices. One is a DAL that communicates with the database layer, one is our Single Sign On / User Profile application that gets called once per page and one is a clone of what seen on the Internet to be used on our lan.

  • UNC vs. SFTP vs. SSH for uploading to a Windows server

    - by apollodude217
    I understand that UNC, SFTP, and SSH are, of course, different interfaces (protocols?). But feature-wise, how do they differ? Are there things you can do with one that you cannot do with another? Is one more secure than another? The situation I want to fix is one where we have several Windows servers and VPC's, some of which have SFTP servers and some of which don't. For those that don't we use UNC over a VPN shared by the entire enterprise. What I want to do is either use all UNC, all SFTP, or all SSH (unless a real need to vary on a case-by-case basis presents itself). Links would be excellent. My biggest problem here is that my googling brings up irrelevant results. :(

  • SQL Server Authentication vs Windows Authentication

    - by Nandu
    Hi, I am a SQL Server newbie and would really appreciate any help. I have created a new login (test2) with sql server authentication and granted select & vierw definition permission on another schema (test1) to test2. I am however not able to see the objects of test1 in the object explorer. However I can select the objects from the Query Window. Since this new login is being used to develop reports the user would like to view the objects in the Object Explorer. Another user test3 created using windows authentication and similar permissions is able to see test1's objects in the explorer. Please let me if this is the cause and if not how can help test2 see the objects in Object Explorer.

  • VMware ESXi VMI Paravirtualization vs 64-bit OS

    - by netvope
    VMware ESXi 4 supports VMI paravirtualization for 32-bit OS but not for 64-bit OS. For performance consideration, is it better to use a 32-bit Ubuntu Server guest without paravirtualization or a 64-bit one with VMI paravirtualization? Hardware: Core 2 Quad, 8 GB RAM Workload: Software development/testing, webserver, database

  • mongod fork vs nohup

    - by Daniel Kitachewsky
    I'm currently writing process management software. One package we use is mongo. Is there any difference between launching mongo with mongod --fork --logpath=/my/path/mongo.log and nohup mongod >> /my/path/mongo.log 2>&1 < /dev/null & ? My first thought was that --fork could spawn more processes and/or threads, and I was suggested that --fork could be useful for changing the effective user (downgrading privileges). But we run all under the same user (process manager and mongod), so is there any other difference? Thank you

  • xinet vs iptables for port forwarding performance

    - by jamie.mccrindle
    I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

  • Hyper-v vs Virtualbox

    - by user53864
    I am using Oracle VirtualBox for ubuntu guest virtual servers on windows server 2008 R2. I'm in a plan to migrate(stop using virtualbox) from VirtualBox to Hyper-V. I guess many are using hyper-v virtualization and have good control over it and could help me here in clarifying few things. The reason I use Virtualbox is it's open source and the reason for migrating is that if hyper-v support any additional feature which virtualbox doesn't(and I couldn't migrate VBox vms along with all the snapshots). I have following questions to get it clarified. Does hyper-v require any licence or is limited to running particular number of virtual machines?. Is hyper-v capable to export/import VMs along with all the snapshots? Is it possible to run HeadLess VMs like it's done with VirtualBox? Does hyper-v recognize VDI/VMDK? Anybody can suggest me anything?. Thanks!

  • Wireless controllers vs wireless usb hub

    - by David Jensen
    For my htpc i currently only have a steerin wheel as a controller. This is wired and it looks really bad having extended usb wires from the tv to the table. However im thinking of bying some new Gamepads and now comes the question. Should i buy wireless ones or wired and connect them to a wireless usb hub? Having a wireless hub would let me manage my gamepads easily from the couch. A wireless hub also allows me to connect other things that are not input devices from the couch. However im wondering if wireless usb hubs may not be made for input devices in the way that they may not have 100% uptime and probably some delay. Am i right about this?

  • HP DL160 G6 memory PC3-10600R vs PC3-10600E

    - by Jeremy Hajek
    I am using a HP DL 160 G6 server that according to specs takes PC3 Registered or Unbuffered. When I combine the two types of memory below the system will not POST. When I use just the first type of memory listed the system will POST. I have two pieces of HP memory that came with the server labeled PC3-10600E-9-10-E0 and then I have some Crucial memory labeled PC3-10600R-9-10-B0 I wager that the R means Registered memory and the E means ECC - then shouldn't the crucial memory boot with the system according to the HP specs? Or does the E mean it is Unbuffered and therefore I shouldn't mix and match as according to this HP memory config doc?

  • Redundant Router and Load Balancing vs. DDoS attack

    - by colgatta
    With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?

  • RS-232 vs. RS-485

    - by user60524
    Doing a little research on the two to figure out which one may better suit my purposes (communications amongst different hardware). How do they fare against one another? Im far from being a specialist and have no idea where I would even start looking for data to compare and contrast. If possible can someone please answer the following questions in regards to each of these. Can they be networked amongst each other? Can they be easily networked over ethernet? What speeds do they transfer at? (Min, Max, Etc.) Reliability? Best framework to build on top of to support the above? Any standard communications programs? Debugging capability? Any help would be very much appreciated, thanks.
