Hopefully those of you that own clusters appreciate the value of “no news is good news”
Working clusters don’t create news. By design; services are available, users are content, administrators enjoy uptime (and their freetime), and life is brilliant.
And so is the life of a cluster software developer; no news (uhm, blogs) means good news but we’re all working hard laying interesting foundations for our highly available futures…
So here’s some recent news:
BCC 1.1 is in beta – the next version of Novell’s Business Continuance Cluster product for NetWare and now also OES Linux, with a number of great new features including health based auto-site failover, support for mixed (NetWare and Linux) BCC’s, and better integration with (CIM/SMI-S based) storage hardware.
(We think SMI-S is an important standard for storage management; and there will be more SMI-S related news in the future).
See https://www.novell.com/coolsolutions/feature/17291.html for more details and how to join the BCC 1.1 beta program.
From the NCS development lab – the 1.8.2 cluster codebase is now running natively on 64-bit (Linux) servers. We’ve got mixed 32-bit / 64-bit clusters working too, and are interested in feedback on how you plan (or might expect us to support) 32-bit to 64-bit migrations.
We’ve been experimenting with Serial Attached SCSI (SAS). Imho, it’s a really interesting technology for building share-disk clusters. Check out SNIA’s tutorial: SAS_and_SATA_Revolutionizing_Storage_Architectures.pdf
If anyone is interested in cluster resource health monitoring and automated recovery, we’d love to hear from, we have some stuff running in the lab that leverages the Python process monitors built into ncs-resourced for NCS Linux.
We’ve also been releasing some of our code into open source. For example, the integration between NCS and EVMS available in OES Linux evolved into some code contributed upstream at evms.sourceforge.net. And we’ve created an EVMS plugin for SLES10’s iSCSI target software. This is kinda cool because it lets you use EVMS tools to create and manage logical (disk) volumes that are automatically exported to iSCSI as whole virtual disks that can be shared by your clustered servers running either OES NetWare or Linux.
Bye for now, Robert
