Great co-hosted Red Hat & Splunk discussion about CloudForms-Splunk integration! Goal: Measure CloudForms utilization by date/time, by user, by cloud povider, and totals. Simple rsyslog config to send the right data over into Splunk, then just add the "Splunk for Red Hat CloudForms" app -- the metrics stated in the above goal are there, right … Continue reading Campground: CloudForms + Splunk

Distributed File System Choices: Red Hat Storage, GFS2, & pNFS
Red Hat has several options for storage needs -- GFS2, CIFS, (p)NFS, Gluster. It's all about right tool for the job. http://www.redhat.com/summit/sessions/index.html#103 RHEL Resilient Storage - GFS2 Shared storage, scales up to 100TB per instance, supports 2-16 nodes in the cluster, x86_64 only. Performance is directly related to server and storage class, and to access … Continue reading Distributed File System Choices: Red Hat Storage, GFS2, & pNFS
SELinux for Immortals
SELinux provides *very* strong sandboxing capabilities. In very simplistic terms --- access control can now be applied not just at the filesystem, but also across network access, X access, enforced and automatic chroots that are cleaned-up when the process ends, all with fine-grained audit logging. But -- this ain't your grandma's chmod. There is some … Continue reading SELinux for Immortals
Application High Availability in Virtual Environments
http://www.redhat.com/summit/sessions/index.html#394 Great discussion around Red Hat's solutions for clustering, fencing, etc, in virtualized environments. Fencing is /very/ important for shared resources, especially disk. In a virtualized world (RHEV, VMWare, etc), fencing tools can reach right into the hypervisor to kill a failed node in a cluster. Similarly, ILO, RSA, DRAC, etc can be used to … Continue reading Application High Availability in Virtual Environments
Simplified VDI with Red Hat Enterprise Virtualization for Desktops
The Red Hat VDI solution has come a long way ... client-side rendering and media off-load, built right on top of the RHEV stack (no separate infrastructure!), user portal is part of the package (no additional purchase!). Comparisons between VMWare View and XenDesktop show roughly functionality/feature parity, but Red Hat VDI appears *much* less expensive, … Continue reading Simplified VDI with Red Hat Enterprise Virtualization for Desktops
