Solaris 10 - Memory / Swap

Hi all

Got myself in a pickle here, chasing my own tail and am confused. Im trying to work out memory / swap on my solaris 10 server, that Im using zones on.

Server A has 32Gb of raw memory, ZFS across the root /mirror drives.

Code:
# prtdiag -v | grep mem = Memory size: 32768 Megabytes
# sar -r 11 shows
09:44:23 freemem freeswap
09:44:24 435917 12672432

Freemem ( pages ) x 4 / 1024 /1024 = 1Gb. However, I was expecting to see 32Gb ??? The server isnt being used, i.e. nothing running at the moment e.g.

Code:
# vmstat 1 10
kthr memory page disk faults cpu
r b w swap free re mf pi po fr de sr m2 m2 m2 rm in sy cs us sy id
0 0 0 7892184 4995808 15 57 10 10 10 0 0 3 3 3 -0 915 194341 894 1 0 99
0 0 0 6336576 3495184 13 56 0 0 0 0 0 0 0 0 0 895 1941052 672 5 1 93
1 0 0 6336344 3495040 2 10 0 0 0 0 0 0 0 0 0 918 1939210 675 5 2 94
0 0 0 6336344 3495040 2 2 0 0 0 0 0 0 0 0 0 959 1938490 790 5 1 94
 
# swap -s
total: 828456k bytes allocated + 162592k reserved = 991048k used, 6336824k available



If I go onto another server, Server B, a 6800 chassis runing solaris 10, with 16GB of Physical memory, no ZFS.

Code:
# sar -r 1 1
09:52:04 freemem freeswap
09:52:05 1850157 42102320

1850157 *4/1024/1024 = 7Gb
 
# swap -s
total: 595800k bytes allocated + 319040k reserved = 914840k used, 21040344k available


Im totally confused. Can someone give me a quick guide /tip to working out memory / swap and how to calculate what is being used / free ?

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME
mdbFontSize - Font Size DESCRIPTION
In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format. FONT-SIZE-ADJUSTMENT ::= PER-FONT * PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')' FONT-SPEC ::= '(' [ FOUNDRY FAMILY [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]] REGISTRY ')' ADJUST-RATIO ::= INTEGER FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font. See m17nFont for the meaning of each property. ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT: ((devanagari-cdac) 150) instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is 'devanagari-cdac'.
