  • Load balancing solution for 2-3 web servers

    i am looking for a solution for load balancing between 2-3 servers in the same datacenter. i saw the ACE 4710 but that seems expensive compared to the rest of the the cisco gear in that datacenter. anybody knows what would be an entry level load balancing solution (2-3 web servers)? thanks in advance.

    the Ace appliance is the new generation and if you take the lowest license 1/2 Gig you should pay a lower price.
    You can still buy the old generation.
    This would be the CSS11501.
    If you need SSL offload this comes by default with ACE but no the CSS.
    CSS11501-K has the SSL offload feature.
    Also note the appliance has many more features which can be turned on by simply adding a new license.
    So, if your site grows and you require more functionalities or more BW, you won't need new hardware.

  • Acrhitecture of network load balancing solution

    i'm working on a setup that will transition our existing data center setup to a network load balancing solution. i'm far from understanding what components to use and how to approach the problem so any help would be very welcome. here is what we currently have:
    1. 3 web servers (serverA, serverB, serverC)
    2. 1 sql server
    3. 2 layer two unmanaged switches
    4. 1 cisco firewall
    each one of the web servers runs a dedicated web app. what i would like is to replace serverA with a NLB cluster of 3 servers and replace serverB with another NLB cluster of 3 servers. serverC is not getting that much usage and it can stay as is.
    i have looked at possible solution with Windows Server 2008 NLB and it seems that the best way to do it would be using multicasting which requires upgrading out switches. at the same time if would much more prefer to use hardware load balancing than Windows Server. so i looked at Cisco ACE 4710 appliance. however it seems that some of the cisco switches will also do load balancing. now i'm completely confused whether to upgrade the switches and use them for load balancing or use the ACE appliance. i would appreciate any advices and suggestions. also, any recommendations on breaking up the network using VLANs - if it is necessary with either one of the solutions or if there is some benefit. i guess i'm looking for a "best practices" solution...
    any links or documents would be very welcomed.
    thanks.

    thanks for your response. i think i'm going with ace 4710. now, as far as vlans go why would i need internet, dmz and internal vlan in my datacenter? i understand that this may be a bit off topic but what is really bugging me is this: with the current setup all of the web servers have 2 nics - one with public IP and one with private IP. same goes with the sql server. on web servers nics with private IPs are used for communicating with the database server. they could very well communicate using nics with public IPs but the person that set this up (i recently inherited it) was convincing me that with the existing setup "public" nics are not burdened with communication between web servers and database server. is this "correct" way of doing it?

  • Load Balancing Solution

    Folks:
    I need to implement a load balancing solution pretty soon and I would like some ideas regarding topology, design and methodology.
    This is what I have:
    1.) Two 7600 Aggregation routers with 4500 L2 server farm switches hanging off of them in a looped topology.
    2.) Load balancers (either an ACE module or an ACE appliance).
    3.) 4 vlans with a cluster of DNS servers in one, a cluster of DHCP in another, and 2 application server clusters in the 3rd and 4th.
    What I need to know is what approahes I can take regarding routing methodology, L2 adjacency, general approach, connectivity, etc.
    I know this is a loaded question, but if I can get 2 or 3 complete solutions from the folks on this board, that would be awesome!
    Im about to board aplane, so I cant respond to queries until about 3 hours or so.
    Thanks!

  • Load balancing algorithm for groups in RZ12

    Hello,
    I would like to know the load balancing algorithm for groups defined in RZ12.
    I know that log on groups for external connections are administered via SMLG and table RZLLICLASS.
    I also know that RFC resources can be managed for RFC logon groups via RZ12.
    Kind regards,

    Hello!
    Found this post while searching information about RFC and Logon Groups...
    I have some mess in my head with SMLG functionality and RZ12. As I know SMLG we can use to distribute users to application server instances, it gives us good achievement in performance. With RZ12 we can distribute RFC connection of particular job for parallel execution on predefined application server. With SMQS and SMQR transaction we can set "Name of AS Group" to route RFC-execution on certain server or servers. But I have troubles with understanding. Imagine, we set up group 1 with 2 servers (name it RFC_GR1), and group 2 with another 2 servers (name it RFC_GR2). How could qRFC scheduler decide on which RFC server group (RFC_GR1 or RFC_GR2) distribute RFC-execution? How to interact "Name of AS Group" with RFC groups if we can set only one group?   How could we distribute RFC-execution depending on our logon groups (smlg)? We would like to distribute RFC depending on SAP logon groups. Is it possible? Or do I compare apple and orange?

  • LOAD BALANCE BEHAVIOR FOR 7600 ON ETHERCHANNELS

    Hi Everyone,
    Currently I'm planning to implement ether-channels on 7600 routers, but there's something that's still not clear to me, regarding the load balancing behavior, for L2VPN and L3VPN.
    I've read that 7600 in MPLS default load balance behavior is to take  the SIP and DIP if present and the bottom of the stack label or the 5th label depending upon the number of labels on the stack. In l2VPN scenarios when ether-channel is used, if no IP traffic is present what is the default behavior of the etherchannel to calculate the load balancing hash function to select a given link on the bundle.
    I'll appreciate any feedback regarding this.

    Hi Louis, you could set default routes on the ASA's with tracking, and use ospf downstream to inject the default route in to the network with default information originate - this will only advertise out a default route if it has it in the routing table. With SLA you can track internet reachability by IP SLA echo to something like 8.8.8.8. Both sides can advertise this in to the network, if one goes then there is one left. Just be mindful of the policies and NAT required, you will have to duplicate the rules on the ASA's. With the NAT you have to ensure, that outgoing traffic comes back in the same path it left so it doesn't break connections.

  • What is the best & cheap backup solution for a macpro laptop?

    What is the best & cheap backup solution for a macpro laptop? easy & simple to use

    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components: 1. A Time Machine preferences panel as part of System Preferences; and, 2. A Time Machine application located in the Applications folder. It is used to manage backups and to restore backups. Time Machine requires a backup drive that is at least twice the capacity of the drive being backed up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    Synk Pro
    Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files.
    Although you can buy a complete external drive system, you can also put one together if you are so inclined.  It's relatively easy and only requires a Phillips head screwdriver (typically.)  You can purchase hard drives separately.  This gives you an opportunity to shop for the best prices on a hard drive of your choice.  Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu.  You can find reviews and benchmarks on many drives at Storage Review.
    Enclosures for FireWire and USB are readily available.  You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports.  I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.)  You can find enclosures at places such as;
    Cool Drives
    OWC
    WiebeTech
    Firewire Direct
    California Drives
    NewEgg
    All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover.  Usually the only tool required is a small or medium Phillips screwdriver.

  • Load balancing plugin for Sun WS 6.1

    Where can I find details about the load balancing plugin for Sun Java Web Server 6.1?
    Can I work around that by using the reverse proxy plugin and configure to work as a Load balancer?
    thx
    Anand

    Details about using the reverse proxy plugin can be found here:
    http://docs.sun.com/source/819-0902/rpp61.html
    The reverse proxy plugin can be used for load balancing. Use the service-passthrough Service SAF for this purpose. You are particularly interested in the "servers" parameter
    "servers - A quoted, space-delimited list of the servers that receive the forwarded requests. Individual server names may optionally be prefixed with http:// or https:// to indicate the protocol and/or suffixed with a colon and integer to indicate the port."

  • Dual Nic Load Balancing Solution

    Hi,
    I have a very peculiar situation. I'm currently a college student with access to an almost unlimited network. But the problem is that the network limits each IP to 30 Mb/s. I have 2 nics at my disposal and have tried two options so far:
    bonding
    two independent nic, let network manager take care of it
    I set-up bonding and got it working, but it seems limited to roughly the same speeds as a single nic, but I can see the network being slit between the two nics evenly. This is what lead me to conclude that since I have a single ip address it's limiting it by IP not mac addresses. Here I might occasionally spike above the limits but not consistently.
    With the network manager solution, Im basically thrown at random and can occasionally get higher than limited speeds. Specially with torrenting clients.
    Are there any other useful options that I could explore, my next stop was a load balancing routing table but I want to see what you guys know before I keep trying weirder solutions.
    Thanks in advance

    Oh come on, we'd all do the same thing if we could double our available bandwidth! 
    I really can't provide much of a solution.  I did this back with my dialup days, many many eons ago.  I used 2 phone lines bonded to get my 56k speeds doubled.  It was a gigantic pain in the rear to set up back then, as well.  However, I'm lucky to remember what I had for breakfast, so remembering how I did something 15+ years ago is pretty much out of the question.
    I'm sure linux can do this, but I'm guessing one of the BSDs would have information about how to do this written up somewhere.  This is right up BSD's alley.  They have all kinds of load-balancing code built into their network stack (Amazon actually had a lot of trouble keeping up with demand when they were getting big, so they wrote up their own networking stack, which has since been returned to the FreeBSD project, iirc).  So it might be worth your time to check that out and possibly run a mini BSD setup on an old computer or something to route the bandwidth to an internal network (of course this would likely require three NICs in a single computer...so more complexity there too).  Some of the problem you are running into may be due to the network just being congested, which could explain the differing speeds.  Then there may be an issue with certain servers not being able to push out 60 MB/s worth of data to you, for whatever reason. 
    Either way, please keep us posted about what you do and how you do it, I'm anxious to find out the final solution here.
    Best of luck to you.

  • Load Balancing 11i for both Intranet & Internet Access

    Our current environment for 11i (11.5.5) is accessed only internally (via Intranet). We need to allow outside access (via Internet) also for self-service apps (ie. HR). Oracle Support/Metalink has stated that Load Balancing (note 148155.1) is the only supported method to have multiple (Apps Servers) systems access a single database. Could I get feedback from anyone who has implemented Load Balancing for 11i? Additionally if someone has implemented this for both intranet and internet access how has your company setup? Do the secondary server(s) from the Load Balancing note reside in the DMZ? And thus the primary app server and database reside inside the firewall? Thanks....

    Hi,
    We are using 6 middle tiers for internal access for intranet access and 2 middle tiers in External DMZ with only web server running for Extrenal Access over Internet for Self Service.
    You Implement one Load Balancer for first 6 internal Middle Tiers with site level profiles pointing to Internal .
    You implement second Load balancer for external 2 middle tiers with server level profile options for these two servers pointing to External Load balancer .

  • Azure Load Balancer - Query for VMs in rotation or removed from rotationq

    From what I can tell, there is no way to know if any of the VMs configured as part of a Load-Balanced Set has been taken out of rotation. I see a PS script to set the Azure Load Balancer Endpoint -

  • Load Balance method for proxy - ISA or BlueCoat

    Hi,
    I would like to know that which load balance method such as src-ip, cookie or etc is most suitable for load balancing proxy servers such as ISA or Bluecoat. The Proxy will listen to many services - http, https, ftp, and etc. Thanks for the help.

    The methods you mentioned are not loadbalancing technics, but stickyness features.
    Stickyness is not always necessary.
    Now, for caching devices, it is good to always send users requesting a same object to a single proxy, so that the same object is not cached in all the proxies.
    Therefore, the solution in this case is loadbalancing with url hashing.
    For HTTPs, if you terminate SSL on the loadbalancer, you can use the same solution.
    For all the other traffic, I would suggest to start with roundrobin and see after a while if it requires some adjustments or not.

  • ACE Load Balancing Configuration For NATed User Traffic

    Hello,
    I am currently working on a requirement where the shared application services will be hosted in DC and these services will be accessed by multiple (thousands) users from different corporates/customers. The user traffic will be hidden behind customer's proxy servers or firewalls so the load balancer (ACE modules) services hosted in DC will not be able to see requests coming in from induvidual users IP addresses.
    In this scenario what are options of load balancing are available in Lyer3/4 and Layer7 ?
    Thanks in advance for your help.
    Sanjay

    Hi Sanjay,
    In a set up where all users are coming from behind a proxy, all users will be loadbalanced to same server thus overloading it. This is when you are doing standard L3/L4 LB.
    In the situation of proxies, for HTTP applications you shall use L7 LB and use information(cookie) in HTTP client request or server response. The ace will use this information to stick the user to same server for persistence. If a client comes with no cookie it will be loadbalanced according to the predictor method configured. Below is the link for L7 configuration example and other TS steps you can take while configuring L7 policies on ACE. For more informatin i would suggest reading ACE user guide too.

  • Problem Load Balancing connections for Grid Control Console on port 80!

    I have two OMS and I'm balancing connections for Grid Control Console using a Software Load Balancer according with "Oracle Enterprise Manager Advanced Configuration". I have success where the load balancer is listening on port different to 80. When I configure Load Balancer to listen on port 80(architecture requirement) and distribute load between the two OMS(Port 7779), when login to Enterprise Manager Console the URL on the web browser changes to the port configured for HTTP server (port 7780) wich produces an "unable to connect" error message; and this behaviour also happends in some of the internal links of Grid Control Console too. Any ideas?
