The T-Finity tape library can scale to 30,000 drive slots, 120 drives, 25 frames and hold up to 45 petabytes (PB) of capacity. A T-Finity library complex, which takes up four data center rows with robot extensions that let robots pass between rows, can scale to 120,000 slots, 480 drives, 100 frames, and 180 PB capacity.

Bigger than IBM, Sun tape libraries
By comparison, IBM Corp.'s largest tape library, the TS3500, scales to 1,000 slots for IBM TS3592 tape drives and up to 1,320 slots for LTO, for 3 PB or 2.1 PB capacity respectively. A TS3500 complex can scale to 6,887 slots, 192 drives, and 16 frames. The Sun StorageTek SL8500 tape library can scale to 10,088 slots, 64 drives, 6 frames, and 15.1 PB. A complex of seven libraries can hold up to 70,616 slots, 448 drives, 42 frames, and 106 PB.
The T-Finity also adds the first support for multiple robots, which can be used to boost performance or for high availability access to the library. It will support LTO and IBM TS1130 tape drives.
The product went into beta in October, and will see limited availability before the end of the year. The base price for the tape library starts at $162,800.
T-Finity beta tester Bill Allcock, director of operations for the Leadership Computing Facility at Argonne National Labs, said he picked Spectra's T950 two years ago over ADIC (now Quantum Corp.'s) i2000, the Sun/StorageTek SL8500 and an IBM library.
"We ruled out ADIC almost immediately, because of their response to our RFP," Allcock said. "We asked for all kinds of details projected over five years and they responded with five one-page quotes and their installation guide."
Spectra's T950 was slightly denser than IBM's offerings at the time, which swayed Allcock toward Spectra. On a technical basis, it was "a horse race" between Sun and Spectra.
"I would've been completely comfortable with either product," Allcock said. "It's a design decision, really a matter of preference. I preferred Spectra's model."
Allcock said there were limitations to the T950 tape library design that might have put off some enterprise customers, such as the lack of support for a high-availability configuration with multiple robots. "What hurt them prior to the T-Finity was not having dual robots," he said. "For us, swapping out a robot in 15 minutes isn't a concern, but if it was a must-have, we would've gone with Sun."
Allcock said Spectra has been responsive to his requests for more features, including support for Unix-based system logs that would allow his team to execute scripts against the tape library the way it does with the rest of the machines in its environment. The Argonne data center draws two megawatts of power, when its cooling system becomes overwhelmed a script will perform a controlled shutdown of machines to minimize heat in the data center. Spectra also made adjustments that helped Argonne add the T950 to that program as well.
Although he's put the T-Finity through its paces as a beta site, Allcock said he's not going to upgrade immediately because he doesn't have a need yet for more capacity, but may upgrade later on.
Competition seen as good for data backup tape library industry
Spectra Logic has been around since 1979 but has recently started to raise its profile as the market consolidates and tape library use remains strongest in large shops. It recently introduced updates to its BlueScale management software that integrates with its nTier data deduplication products as well as its tape libraries.
Data backup and recovery expert W. Curtis Preston said it's good for the tape library market to have a newly aggressive competitor. "For a small company like Spectra to leapfrog IBM, Sun and Quantum in tape library capacity and density like this is awesome," he said. "Spectra has always impressed me with its ability to go big [with products] and stay [a] small [company] at the same time."
In his consulting work, Preston said he has seen some shops switch to Spectra from Sun, particularly given the pending Oracle/Sun merger.
"I see shops switching to them all the time," he said. "It's not just uncertainty [about the Oracle deal]. It's people thinking that StorageTek lost its vision once it was acquired by Sun."
