Gould have implemented both the Sun Network Disk (ND) protocol and the Sun Network File System (NFS) on their machines, allowing the use of Sun diskless nodes without a Sun disk server. Has anyone implemented the ND protocol on the VAX? I know that Mt XINU have implemented the NFS on the VAX, but with that I will still need a Sun disk server to run diskless nodes. I am looking to protect existing investment while moving to workstations and would like to turn one of my VAXes into a disk server cum file server. Thanks in anticipation.

Ok: One More Time.... (BTW, for those who care, the "other changes" we haven't made are that on Suns, physstrat() maps in the pages being accessed, while on Vaxen it's done with UBA or MBA maps---except of course for the network disk, which doesn't have UBA/MBA map registers.... It would be necessary to allocate a map [in locore.s] and map in pages being accessed, and mtpr(TBIA) and all that stuff.) Chris ------------ *You* can have source code for the Sun Network Disk implementation! We constructed this source code by decompiling 68000 object code into canonical-style 4.2bsd Unix kernel source. (It wasn't easy.) We are using this code in all our Sun kernels, and on two of our vaxen. Raw and page access to remote network disks doesn't yet work on our vaxen because we have neglected to make other kernel changes necessary to support this. Please note that this has nothing to do with the Sun Network File System (tm). We will send you our decompiled source code and some diff listings for vax kernel sources that we've been forced to change to support the network disk code. To obtain this source code just send: a) One copy of your SUN source code license. b) A letter requesting the "Network Disk Source Code." c) A check for $50 made out to "University of Maryland Foundation." to Diane Miller University of Maryland Software Distribution Department of Computer Science University of Maryland College Park, Maryland 20742 -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 4251) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
