Installing mSATA Solid State Drive in Dell Precision M3800
I'm considering getting a Dell Precision M3800 Mobile Workstation, would
want to install my own mSATA SSD in it. Does anyone here have one of
these machines? If so, is an SSD a user-installable component? And if
so again, how much needs to be taken apart?
Thanks much.

What is the 32 GB 2.5-Inch SATA Solid State Drive?
Does anyone know about this device?
SESX3Y11Z 32 GB 2.5-Inch SATA Solid State Drive with Marlin Bracket
for Sun SPARC Enterprise T5120, T5220, T5140 and T5240 Servers, RoHS-6
Compliant
This is from Sun''s catalog for the T5120 server. Would this work well
as a separate ZIL device for ZFS? Is there any way I could use this in
a T2000 server? The brackets appear to be

program in Wine doesnt see SATA solid state drive
I have a 50 gig OCZ Vertex LE drive that needs a firmware update.
When I run the Windows only flash program in wine it doesnt see the SATA ssd drive it needs to flash.
I have booted off another hard disk.
I need administrator privileges to see the drive so I config'd wine for win98.
I also tried to manually add the drive in wine config by adding the /media/xxxx path and also manually

Reseting Echo State
Hello guys,
I want to make echo tail parameter in my app changeable during run-time.
So my question is:f
Should I use speex_echo_state_reset function for this? Just call
speex_echo_state_init function with new values after that?
Or perform a full de-initialization and initialize echo cancellation
with new tail value?
I'm also using preprocessor - does the same apply to it?

solid-state asterisk pbx?
I've been thinking of making a (mostly) solid-state asterisk pbx.
Take either centos or some other distro, cut it down to bare minimum and
put asterisk + AMP on. Something that could be put onto a usb2.0 flash
stick, bootable.
Modern flash devices (usb, compactflash) have builtin wear leveling
management and will last longer than you think:

does sharing an SSD as slog and l2arc reduces its life span?
Hi,
I don''t know if it''s already been discussed here, but while
thinking about using the OCZ Vertex 2 Pro SSD (which according
to spec page has supercaps built in) as a shared slog and L2ARC
device it stroke me that this might not be a such a good idea.
Because this SSD is MLC based, write cycles are an issue here,
though I can''t find any number in their spec.
Why do I

SSD Optimizations
I''m looking to try BTRFS on a SSD, and I would like to know what SSD
optimizations it applies. Is there a comprehensive list of what ssd
mount option does? How are the blocks and metadata arranged? Are there
options available comparable to ext2/ext3 to help reduce wear and
improve performance?
Specifically, on ext2 (journal means more writes, so I don''t use ext3 on
SSDs,

Fwd: Current State of BTRFS
Hi everybody,
I am using btrfs as my main fs for some time now, but I am
experiencing severe performance drawbacks. I can''t qualify the
circumstances, but sometimes during disc access the whole system
freezes for some time.
Maybe somebody could suggest some general things I could try to search
for the problem?
Thanks in advance,
Florian

Secure delete?
Hi all
Is it possible to securely delete a file from a zfs dataset/zpool once it''s been snapshotted, meaning "delete (and perhaps overwrite) all copies of this file"?
Best regards

fstrim on BTRFS
Hi!
With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it
trimmed:
merkaba:~> fstrim -v /boot
/boot: 224657408 bytes were trimmed
merkaba:~> fstrim -v /boot
/boot: 0 bytes were trimmed
But BTRFS does not:
merkaba:~> fstrim -v /
/: 4431613952 bytes were trimmed
merkaba:~> fstrim -v /
/: 4341846016 bytes were trimmed
Is it planned to add this feature to BTRFS

sudo in switchtower and security
I''m attempting to deploy a rails application using switchtower. My IT guys
are refusing to give me sudo for a user changeable script. I really can''t
argue with their logic. If I have sudo for a script that I can update, well,
I can do most anything I want.
They are suggesting I create a cgi that performs the same function. Since
the cgi would run as www-data (this is a debian

[PATCH] virtio-net: parameterize min ring num_free for virtio receive
This change makes ring buffer reclaim threshold num_free configurable for better performance, while it's hard coded as 1/2 * queue now.
According to our test with qemu + dpdk, packet dropping happens when the guest is not able to provide free buffer in avail ring timely.
Smaller value of num_free does decrease the number of packet dropping during our test as it makes virtio_net reclaim buffer
