We moved from a L700 [8 LTO1] with 218 slots to a SL500 [6 LTO3] 146 slots 
[forgive me if the slots # are off]  and found that the SL500 is WAY much 
slower grabbing tapes and Networker cries much more often giving off its 
critical warnings waiting for a tape.  

That said it is also a given that the library was a total upgrade from 7.1.1 to 
7.3.4 so there might be some binary involved there.

Subject: [Networker] Upgrade to LTO4 library, opinions about these libraries ?

Hello,

We're evaluating different offers por changing our old library (a 
Qualstar TLS6460 with 60 slots/4 drives SDLT320) to a new LTO4 library 
with FC interfaces.

Our initial idea is to connect the library (i.e. its 2 initial LTO4 
drives) directly to the server using a dual channel HBA interface, but 
we are evaluating the connection to our SAN too (for having some hosts 
direct backup to the library like storage nodes).

We have different offers by our providers and we would like to hear your 
opinions about these libraries (support, problems, evolution, etc.):

* SpectraLogic Spectra T120 (30 slots, 2xLTO4,
* Quantum Scalar i500 (41 slots, 2xLTO4, I/O magazine 6 slots)
* Dell PowerVault ML6010 (41 slots, 2xLTO4, I/O magazine 6 slots)
* Sun StorageTek SL500 (30 slots, 2xLTO4, CAP magazine 5 slots)

Thank you very much!
