The Netherlands manufacturer Ardis Technologies, exhibiting under their product name Dynamic Drive Pool (DDP), is demonstrating new software for its storage appliance at NAB.
“Until today users can share their data working with one DDP,” explains the company. “Worldwide many DDPs are in operation this way. With Version 5, users can share their data within multiple DDPs (data locations) within one DDP volume. That is, the DDPs must be on the same Ethernet net or subnet. Especially with microDDPs, they can be here, there or elsewhere since they are very low power and no machine rooms are required.”
The vendor continues: “DDPs can be combined with one DDP holding the metadata and one Web interface to administer. Data is transferred in parallel and bandwidth scales linear in steps of 2,2 GB/s while adding microDDPs. Depending of course on bandwidth and latency of the network. There are many setups possible such as: within a building in a machine room, within a building in each studio (no machine room needed), between buildings on a campus, between companies in an area, between cities in a company, between countries, fixed and outside broadcast installations. Think of the power savings. Think of the space savings. And remember each setup involves one admin web interface to control users, groups, data access, activity and locations here, there and elsewhere.”
The microDDP10GbE is 1U, 19”, has a depth of 10” (25,5 cm) and can be hand carried (11 lbs, 5Kg). It currently comes with either 8 x 1 or 8 x 2 TB SSDs in raid 5 with an effective capacity of 7 or 14TB. It has dual 1GbE/RJ45 and dual 10GbE/RJ45 ports which can be used also as 1GbE. These four ports give a total bandwidth of 2.2 GByte/s. A microDDP10GbE with capacity up to 60TB can be offered upon request. For other flash requirements a 4U miniDDP48D can be offered.
Regarding hybrid technology: each DDP consists of a DDP base system which can be optionally filled with SSD and or HD packs of different capacities and 1, 10, 40, 100 GbE network cards and ports. So each DDP other than the microDDP can be all flash, hybrid or all spindles.
On the web interface in the Storage Manager these packs show up as data locations. Also storage arrays such as DDP16EXR, DDP24EXR and DDP60EXR show up as data locations when added. To avoid complexity, the selection of a data location in the Storage Manager has been limited to folder volumes. Folder volumes are folders with volume properties. They reside within the DDP Volume. Selection possibilities are: a data location, load balancing with the data balanced on all data locations and on demand or pinned SSD caching.
On demand caching means that data is copied from spindles to the SSD data location when a file is opened. When pinned is selected the data from the folder volume is cached to the SSD data location. Storage arrays can be added at the back without changes at the front end. After adding the storage array(s) the data redistributes automatically.
