Storage analyst Deni Connor focuses on storage, application and infrastructure management in this twice-weekly newsletter.
HP last week introduced not just one, but two data deduplication technologies that let IT reduce the amount of data they back up.
The two types of data deduplication focus on two different customers. The HP StorageWorks D2D Backup Systems are designed for use by small and midsize businesses. The HP StorageWorks Virtual Library Systems (VLS) are existing virtual tape libraries with deduplication capability added – they are designed for large enterprise-size customers.
The HP D2D Backup Systems include the 2500 and 4000 models, which deduplicate data as it is stored to disk. They emulate as many as 16 LTO tape autoloaders or libraries and can consolidate the backup of as many as 16 servers onto a single device.
The HP VLS system emulates multiple tape libraries and deduplicates data after the backup has completed writing data to disk. It is also available in two models – the VLS6000 and the VLS9000.
The HP StorageWorks 6000 VLS is a single-node system that scales to 600Mbps and 106TB of capacity. It uses 2:1 hardware compression and hardware RAID 6 to minimize data loss. The VLS6000 supports up to 10,000 slots and 32,000 tape cartridges. It emulates the HP ESL E-series, MSL tape libraries and 1/8 autoloaders, as well as HP Ultrium 230 (LTO-1), HP Ultrium 460 (LTO-2), HP Ultrium 960 (LTO-3), HP Ultrium 1840 (LTO-4).
The HP StorageWorks VLS9000 is a multi-node solution that performs up to 4,800Mbps and has a capacity up to 1,280TB. Like the 6000 VLS, it offers 2:1 hardware compression and hardware RAID 6 support. It will support 1TB disk drives and LTO-4 tape emulation. Also like the 6000 VLS it supports up to 10,000 slots and 32,000 cartridges. The HP StorageWorks D2D 2500 and 4000 systems start at $6,500.
Both VLS models are the result of an OEM deal with deduplication vendor Sepaton. The HP D2D Backup Systems are internally developed at HP.
The HP StorageWorks VLS6000 and VLS9000 series are priced based on capacity. (Compare Data Backup and Replication products)

What is all the fussBy tmasters on July 7, 2008, 10:54 amI'm still trying to sort this out. This may turn out to be a great move by HP, but it is based on Sepaton's technology which has been considered across the industry...
