Hello All,
Pls i need your assitance. I installed an oracle/sun SL500 tape libaray with 5 LTO5 drives, and the library is mannaged by quest netvault 8.0 and 8.1 at different location installed on X86_64 rhhel4u7 x3550 server. The libarary is connect to san brocade switch and the Storage filler where volumes resides is a Netapp storage,also connected to the SAN switch.
the Netvault is able to schedule job to drives at the same time, but two issues needs to be resolved.
1. The SL500 drives at native oerformance should be able to doe 140mbps data at native write, and when compressed it should varry. Its based on this that the customer upgraded from LT)4 drives tape libarray to Sl500., but when wriiting is done the performance speed is between 40mb/s to 57mbps, this varries for each drives when wriiting at once.
The tape drive performance test is ok. pls what can we do on the netvalt application for us to achieve high write performance.
2. If mutiple jobs are scheduled to all the drives, it sis expected that the catridge is removed for the next job to start, the tape media is not removed to the tape lib slots for new data tape to be reloaded into the drive.
Is there anything we can do to schedule this on netvault.
Please I appreciate all response.
Thanks in advavnce.
