KEMP gives away the LoadMaster for free. Now the virtual appliance is available in a free edition too. Available for all supported hypervisors (VMware, Hyper-V, enz).
The free VLM has some limitations, for instance the HA setup with an active and hot stand-by unit is not supported. Another important limitation is that the free LoadMaster doesn’t come with the awesome support paying customers receive. Also there are some bandwidth and SSL TPS limitations, all in all not much special for most home, lab, testing and other non-production deployments.
- The Free LoadMaster Includes:
- Layer 4/7 load balancing
- Content switching
- Caching, compression engine
- MS Exchange 2010/2013 optimized
- Pre-configured virtual service templates
- IPS engine
- High Availability
- Edge Security Pack (ESP) – a Microsoft TMG replacement
- GSLB multi-site load balancing
- RESTful API
I like the Managed Availability and the “self healing” aspect of Exchange 2013.
But about SpaceMonitorLowSpaceThresholdInMB is nothing about to read.
If you check your serverhealt with:
get-serverhealth -identity servername -HealthSet Diskspace | ? AlertValue -ne unHealthy | ft -autosize
You can get lots of Databases which are in an unhealthy state because the LowLogVolumeSpaceMonitor is configured to check if you have 200 GB of free space. That would be an great idea, if you have a large organization and you have lots of disks whith a huge amount of free space. But in smaller company it would be great to change this value.
With Exchange 2013 SP1 you should now be able to configure this. Go to all of your Mailbox Servers and in regedit go to the following path:
If you have an DWORD called SpaceMonitorLowSpaceThresholdInMB then you’re lucky. If not, create a DWORD with the name and then you can change it to an Value which suits you more. But, as the dword is mentioning, its in MB not GB 😉
No Reg Setting but Add-GlobalMonitoringOverride is better!!
write-host = “Default 175GB CU7”
$diskspace = Read-Host ‘What is the Minimum Free Disk Space in MB?’
Add-GlobalMonitoringOverride -Item Monitor –Identity MailboxSpace\StorageLogicalDriveSpaceMonitor -PropertyName MonitoringThreshold -PropertyValue $diskspace
