low end file server with h/w RAID - recommendations
>Most servers can fit only 2.5" disks these days. I keep wondering what everyone is doing about storage.
The DL20 gen9 I bought was setup LFF (3.5")
The DL380 gen9 could be either SFF (2.5) or LFF. I had to buy SFF for our new server due I was told to spec / build it exact to vendor recommendation.
To better? Answer this. Agreed, I'm not a fanboy of 2.5" stuff in enterprise equipment. To me a better but more costly answer...

[patch] Support many columns in model.matrix
Generating a model matrix with very large numbers of columns overflows
the stack and/or runs very slowly, due to the implementation of
TrimRepeats().
This patch modifies it to use Rf_duplicated() to find the duplicates.
This makes the running time linear in the number of columns and
eliminates the recursive function calls.
Thanks

Thank you, Karl.
I've committed this (very slightly modified) to R-devel,
(also after looking for a an example that runs on a non-huge
computer and shows the difference) :
nF <- 11 ; set.seed(1)
lff <- setNames(replicate(nF, as.factor(rpois(128, 1/4)), simplify=FALSE), letters[1:nF])
str(dd <- as.data.frame(lff)); prod(sapply(dd, nlevels))
## 'data.frame': 128 obs. of 11 variables:
## $ a: Factor w/ 3 levels "0","1","2": 1 1 1 2 1 2 2 1 1 1 ...

Samba and Active Directory 2008
I was wondering if anyone has had any luck getting samba working with a
Windows 2008 domain? I've got mine working for the most part except for UID
lookups. I've got identity management for unix installed on on the windows
box and have several users configured with custom home directories, login
shell, and UID on the Unix attributes tab. My samba server is joined to the
domain, wbinfo -u

ZFS Appliance as a general-purpose server question
A customer is looking to replace or augment their Sun Thumper
with a ZFS appliance like 7320. However, the Thumper was used
not only as a protocol storage server (home dirs, files, backups
over NFS/CIFS/Rsync), but also as a general-purpose server with
unpredictably-big-data programs running directly on it (such as
corporate databases, Alfresco for intellectual document storage,
etc.) in order to
