The Power Saving Cloud Archive is a high-performance, low-cost, redundant, and robust NAS file server plus an archival storage solution. The Power Saving Cloud Archive (PSCA) uses open standards server and storage components combined with Cutting Edge’s 5th generation EdgeWare OS built on a 64-bit Linux operating system. This combination allows the PSCA to attain a performance vs. price point that is significantly higher than other storage solutions. Open standards internal and external RAID systems, SAS/SATA/SSD disks, high-performance Intel processors, and multiple Intel gigabit and/or 10 gigabit Ethernet ports allow the PSCA to leverage high-quality low-cost components. The open standards approach provides greater cost efficiencies and quicker technology refresh cycles when compared to expensive proprietary hardware and software.
The PSCA provides high-performance network attached storage (CIFS) solution that can scale to the user’s required throughput and storage capacity requirements.
The “magic” of the PSCA is the Long Term Storage Nodes (LTSN). LTSNs can be configured with either dual GbEthernet or dual 10GbEthernet ports to provide performance options to meet any throughput requirements. The ability of the PSCA NAS Server to dynamically power-up and add LTSNs as bandwidth or storage capacity requirements increase and then power down LTSNs as requirements lessen essentially moves any potential bottleneck to the existing public network infrastructure. The ability of an LTSN to power down when not in use and dynamically power on when needed in 30 seconds, creates an ultra-low-power high-performance solution previously not known in the storage industry.
The PSCA NAS Server may be configured with different drive options depending on the use case required. The PSCA NAS consists of at least two separate hardware RAID protected volumes. The first volume is the PSCA protected NAS CIFS share. The PSCA protected NAS share volume can have high-performance Solid State Drives (SSD), high-performance Serial-Attached SCSI drives (15K RPM SAS), or high-capacity SAS/Serial-ATA drives (7200 RPM SAS/SATA) depending on the user’s access specification. The second volume is the fast PSCA database used to track files archived on the LTSNs. The PSCA database volume can have high-performance SSDs or 15K RPM SAS HDDs depending on the user’s file types, sizes, and throughput requirements. Additional volumes may be configured for additional PSCA NAS CIFS shares, non-PSCA NAS CIFS shares, NFS exports, and volumes to be used as iSCSI or Fiber Channel Targets.
The LTSN is configured with twelve high-capacity 7200 RPM SATA drives in a RAID-6 volume.
RAID 6 is used to maximize drive redundancy to ensure availability. The LTSN is available with 2TB or 3TB drives for a raw storage capacity of 24TB to 36TB.
