Double-Take® Software

Key Facts:
  • Double-Take® Software (NASDAQ: DBTK) has announced the availability of Double-Take® 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’ existing SANs.
  • 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.

Product Highlights:
  • 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.
