[SunRescue] Max. Size Hard Disk Installable in SparcStorage A rray

[Garten, David N., CTR, OSD/P&R]

	The older versions of the SSAs (eg 101 and 102) have a 40 MHz
microSPARC-II and 4 MB of RAM. The never versions (112, 114) have 16 MB RAM,
1 MBcache and an 110 microSPARC-II cpu.  
	Anybody know if the 'heart' of the unit is just the interface (i.e.,
a 101 with the controller from the 110 is a 110 in 'sheep's clothing')?  Or
will the firmware / interface / sockets / chassis sneak up and bite you?

Don't forget that they differ in speed of the onboard MicroSPARC CPU
also...
I can't remember all the numbers, but they should be somewhere in the
mailinglist archives.
