• SQL Server Fails to Start When Moved to Different Node

    Sql 2008 R2 on Windows 2008 R2 cluster. When I move instance from node 1 to node 2 everything is fine: all resources come online as they should. When I move the instance from node 2 to node 1, all resources except sql server and agent come online. If I delete errorlog and start the sql server...

  • Does automated failover defeat the purpose of virtualization?

    My understanding of the purpose of virtualization is to reduce server sprawl. In theory if you get one physical server to do the work of two servers you increase the percent of utilization of the server while cutting down on the number of servers in the pool, thus reducing power consumption,...

  • Standby server back-up process

    Assuming that I am in a situation where a primary server is backed-up by a standby server that is testing the pluse beat of the primary. From the instant the backup senses the that the primary server is no longer functioning, how long would you expect it would take for the the backup to be up and...

  • SQL Server Failover Clustering or DB Mirroring

    Hi,   I need to clarify some concerns with regard to the options available on SQL Cluster deployment, but before that let me give you a background on the infra layout so we are on the same page:   We have two physical servers + FC SAN (iscsi not supported in the current model) to setup Hyper-V...

  • When setting up a cluster for failover purposes do you only inclde hardware of one vendor?

    When setting up a cluster for the purpose of failover do you only include in that cluster servers made by the same vendor or can you mix vendors?

  • Counting failovers

    I would like to count the automatic failover that occur in my server pool each month. I don't want the switchovers that are done manually just the failovers, Does anyone have a suggestion where I might find that information recorded. Will it be in the event file of the reciving server or do I need...

  • Active to active failover assumption

    Is it assumed that in an active to active failover involving two or more nodes that there will always be a node that can receive the failover? What happens if there isn't a node that can receive the failover because the other nodes are all maxed out? I can understand why in an active passive...

  • Failover of a virtualized server

    Assume that a virtualized server running five virtual machines has a hardware failure that takes the physical device down, in an active to active failover enviroment of multiple nodes do all the virtual machines failover to the same node in a cluster or could each virtual machine go to a...

  • Cost per server of the failover software?

    What is the cost per server of the software that enables failover? Does the cost change if the failover is active-active or active passive? Does this software have a specific class name?

    What does failover cluster management refer to? Is it a function, as in something a person does or is it a facility as in something someone uses?

  • Why failover applicantion software failures?

    Mrdenny, says that if a cluster resource is configured to failover then it will failover on an application program that fails, but does that make sense? if the application program failed processing a specific transaction on one server isn't it going to fail processing the same transaction on...

  • What kind of failure event would cause a primary server to failover to a standby backup?

    I am aware that in a situation where a primary server is being backed-up by a standby server that the standby server is constantly testing the pulse beat of the primary, what kind of problem will cause a failover to take place. Is it only when the primary stops functioning, does it have to stop...

  • Choosing between failover options

    It seems of the two choices, failover to an active server within a cluster, or failover to an inactive backup standby server, the economic chose would be the former. With the former, the servers in the cluster are all doing productive work while they also act as backup for the other servers in the...

  • Which task does the backup server do?

    As I understand the theory of automated failover, you backup a primary server with a secondary standby server that monitors the pulse-beat of the primary and automatically takes over when the primary server fails. My question is if the primary server is performing a search and experiences a...
