Hardware:
– IBM BladeCenter H
– HS22V and HX5 blades with Brocade 2 port 10GbE Converged Network Adapter, no local drives
– IBM Storwize V7000
At the time of writing the Brocade 2 port 10GbE Converged Network Adapter for IBM BladeCenter (81Y1650) is supported on VMware ESXi up to version 4.1.
To install VMware on the blades, a custom VMware ESXi 4.1 ISO image with Brocade CNA drivers is required.
RHEL 6.1 / Scientific Linux 6.1 dmesg:
TECH PREVIEW: fscache may not be fully supported.
Please review provided documentation for limitations.
FS-Cache: Loaded
FS-Cache: Netfs 'nfs' registered for caching
Excerpt from RHEL 6.1 Technical Notes, Chapter 3. Technology Previews:
FS-Cache
FS-Cache is a new feature in Red Hat Enterprise Linux 6 that enables networked file systems (e.g. NFS) to have a persistent cache of data on the client machine.
… and nothing about the limitations or how to disable fscache.
Tried to add install fscache /bin/true to /etc/modprobe.d/fscache.conf with the following dmesg result (of course, no NFS filesystems mounted):
nfs: Unknown symbol __fscache_read_or_alloc_pages
