At the beginning of this year, WD acquired Arkeia, a company with a long history in the primary backup software market. Arkeia was known in the industry as a technology leader in deduplication, with technology they acquired from Kadena Systems and integrated into their entire product line. Using a process called “progressive deduplication”, Arkeia software provided some enviable data reduction performance in many different use cases.
Arkeia v10.1 software supports an unlimited number of clients on over 200 platform types, plus agents for hot backup of specific applications and databases. WD has been selling rack-mounted backup appliances with the Arkeia software and recently announced the addition of two desktop systems that use WD hardware platforms DX- and DS-series NAS appliances.
The DA1300 and DA2300 are Purpose-built Backup Appliances (PBBAs) that feature up to 8TB of usable backup capacity (16TB raw) in a RAID 1 configuration and up to 16GB of RAM. The DA2300 integrates 128GB of SSD to accelerate backup catalog operations. Both have dual/redundant power supplies, dual/redundant 1GbE NICs and up to four USB 3.0 connections for external tape drives.
WD’s 2U rack-mounted backup appliances provide up to 40TB of usable capacity (48TB raw) in RAID 6, single or dual Xeon processors and up to 96GB of RAM. All configurations include dual/redundant power supplies, four 1GbE NICs, plus SAS connectivity for tape drives. One model contains an embedded LTO5 tape drive. Two models integrate 360GB of SSD and offer optional dual 10GbE cards or fibre channel cards. All appliances except the DA1300 feature what the company calls “enterprise-class” HDDs.
WD also just announced a vStorage agent for VMware vSphere environments running the Arkeia backup software, providing global progressive deduplication for all OSs on all VMs. This VM-based backup appliance supports Change Block Tracking (CBT), image-level full, incremental and differential backups and Microsoft VSS. It’s also vMotion aware and supports VMware’s vStorage API and vCenter.
Storage Swiss Take
WD brings some of the same advantages to this backup appliance line as it does their NAS appliances, given the fact both use the same HA design and business-grade hardware. With the Arkeia software, these backup appliances have several more benefits. In addition to their progressive deduplication, which is much more than a ‘checkbox’ feature, Arkeia also brings a very deep set of supported applications and platforms.
