Software (NASDAQ: DBTK) has announced the availability of
Flex for High Performance Computing (HPC), an all-in-one solution
for diskless iSCSI boot for Microsoft Windows HPC Server 2008 R2
storage, bootstrap and boot volume management
Double-Take Flex for HPC allows companies to virtualize, consolidate,
share, and centrally manage HPC compute node boot volumes
Double-Take Flex for HPC extends Windows HPC Server customers’
investments in iSCSI SAN infrastructure and provides a powerful
underlying iSCSI Storage Server tuned especially for sharing HPC
nodes’ boot images.
It is a comprehensive solution that includes all of the required
technology to automate the deployment of hundreds of diskless HPC
compute nodes, and includes the iSCSI Service Provider,
centrally-managed back-end storage, and boot image management.
Double-Take Flex for HPC can also work with third-party iSCSI
providers, helping to extend the high-end capabilities of customers’
On the same compute nodes, customers can use the functionalities of
both Double-Take Flex and Double-Take Flex for HPC. In this scenario,
a customer could provision desktops for ordinary office tasks during
the day and for high performance computing at night.
Manageability – Before Double-Take Flex for HPC, customers were
tasked with a time-intensive, costly manual process of individually
provisioning each boot volume for each HPC compute node. Now customers
can create and provision all boot volumes at the same time by sharing
a single master boot volume to all compute nodes, while at the same
allowing individual nodes to utilize individual differences.
Flexibility – Double-Take Flex for HPC allows for easy,
cost-effective re-purposing of compute nodes or additional non-HPC
clients for other boot-from-SAN usage. This allows customer to
provision desktops for ordinary office tasks during the day and for
high performance computing at night.
Reliability – Using hundreds of compute node disks together can
be unreliable due to moving parts, but Double-Take Flex for HPC allows
users to replace these unreliable hard disks with reliable and
centrally managed software-based diskless iSCSI boot capabilities.
Costs – Consolidating disks with Double-Take Flex for HPC eases
purchase, power and cooling requirements.
Security – In some HPC environments, disks must be tightly
managed. By having fewer disks, companies can significantly improve
the manageability of physical disks and therefore provide a greater
level of security.
Learning Curve – Double-Take Flex for HPC puts all the pieces
required for diskless HPC boot in one place with one vendor, utilizing
familiar PXE boot technology.

“Windows HPC Server 2008 offers world class performance, takes advantage
of existing technology investments and skills and makes supercomputing
simple to manage and easy to use. Double-Take Flex for HPC brings value
to customers, helping them get their work done in smart, efficient ways.”
