Power Edge R300 and virtualisation
The company i work for boght a new server 1 year ago (spending over $30,000). Here is the configuration:
Hardware and SoftwareVirtual Server Host – Hardware
- Dell PowerEdge R300
- Drobo Elite 4TB
Virtual Server Host – Software
- VMWare Essentials – Operating System
- VRangerPro – Backup with 3 year supportSmall Business Server 2008
the drobo was divided in 4, in order to manage the following functions: email and sql, printers, applications and web server.
Now... we have had so many problems since installation... slowness, full use of memory, server rebooting by itself.
We ask another IT company to look at our configutaion, and these are there findings:
Currently the “idle” system demand is at 40%, which is on the high side (6% is the standard idle percentage that we like to see).
The current Dell PowerEdge R300 server is not recommended for a virtual environment because it is not built for multiple processing tasks (running SBS, Exchange, SQL, etc. all at the same time). It is designed for a single service, not a multi-virtual service environment.
The Dell R300 is the hypervisor host for the virtual machines and the Drobo is the host for the virtual hard drives. This is causing performance issues because the Dell R300 relies on the network to access the virtual hosted hard drives on the Drobo, and not the local hardware, to manage your services (SBS, Exchange, Avanti, Small Business Financials, SQL Server Database, Print Services, Trend-Micro, Terminal Services and the Web Server).
It is our recommendation that new hardware be purchased to eliminate the latency and performance issues that are occurring. We suggest buying two of the PowerEdge R710 rack-mountable servers for two reasons: redundancy and performance (should a power supply, mother board or RAM failure occur you will have a backup). We like to minimize single point of failures with mission critical hardware. The other benefit of this set-up is that it will allow differential virtualization, which allows you to have separate Active Directory servers. For example, if the server hosting Active Directory goes offline, all of the other servers dependant on the Active Directory go offline until the Active Directory comes back online. By having two servers and two separate Active Directories you eliminate this issue.
Can this be true? Can the first IT company be soooooooooo far off?
