Free at last, free at last! JIST is OpenSourced!
By leojava on Nov 13, 2008
As of October 31, 2008, JIST has been OpenSourced. This has been a long time coming.
Why is this important? JIST replaces a 6+ month manual effort using $250,000.00+ hardware resources to validate a SCSI device operates as expected with an automated test taking about an hour total time with less than $2,000.00 of hardware resources. (Nice return on the investment.) And that is just the JIST SCSI Disk Test Suite...
JIST allows Sun to work with multiple vendors to ensure "IT JIST Works"(c) by avoiding communication breakdown between Servers (running Sun Solaris, OpenSolaris, or other OSes) and Storage Devices (like Sun Storage 7000 Unified Storage Systems, Sun Storage J4000 Arrays, and Sun StorageTek 2500 Arrays).
Additionally, JIST offers the opportunity to test high level application requirements with low level protocol tests utilizing OpenSourced and Freely available products. Traditionally, test configurations would include massive investments in licensed products, operating systems, and hardware configurations. Utilizing JIST, the investment can be reduced to JIST, OpenSolaris, Java, Sun Studio, and a Sun Fire X2100 M2 Server.
Is that all? Actually, JIST covers SCSI Disks, SCSI Enclosure Services, iSCSi Targets, Fibre Channel Targets, and CAS protocols. Basically, JIST tests were your data goes to make sure "IT JIST works".
Why would you give that away? Much like other areas, Sun is working to promote standards. Storage standards validated by JIST work to help customer, Sun, and the storage market in general by helping to ensure "IT JIST works". For example, Vendor XYZ now is able use JIST to produce a SCSI Disk with less complexity (e.g. cost & time). Sun and customers are able to utilize the SCSI Disk with greater assurance of customer data integrity. Thus, a Win-Win-Win. As my CEO would say, "A rising tide lifts all boats."
I will be updating the JIST image on OpenSolaris.org the first week of each month. I will be making postings on this blog about every other week. So, check back periodically and get the latest on JIST.
