Back
We are looking to implement our own HA NAS (NFS) Server Utilizing the
following hardware/software;
NASHead1, NASHead2
Dell PowerEdge 1850
Dual Proc, 2GB RAM, 2X36GB 15K (RAID1) for OS
Perc4/DC 1int/1ext
Redhat ES4
Redhat Cluster Suite
Both Connected to;
Dell PowerVault 220s
Dual Enclosure Management Module
Redundant PS
14X36GB 15K RAID5
Both NAS Heads configured for HA Clustering/Failover Using Redhat
Cluster Suite
Taking over the IP and NFS Exports of the failed server.
Has anyone implemented a simliear solution?
Is this configuration known to work (proper control of the External SCSI
by active server, etc.)
Where does the Quoram partition reside?
Known issues? Comments?
We had originally planned on implementing 2 PowerVault 775N's with
Cluster option, but that product has been discontinued.
This will server a Linux only environment.
Our other option is to use Microsoft Advanced Server? Clustering, but
would prefer to keep the entire environment running Linux.
