SATA raid: single point of failure? by
Jim Wall
With SATA drives in a raid array, is the raid controller always going
to be a single point of failure? In other words, is there any way to
have two fully independent raid controllers accessing the same SATA
drive?
Here is more detail of my concern. Using FC drives, I have two fully
redundant...

Storage across multiple servers? by
JB Orca
I am trying to find out how to do something that does not make much
sense to me. I have spoken to a few people who say they have taken
multiple servers (1u in this case) and striped the drives on those 1u
servers so that all servers in the group were seeing all data on all
servers.
Does this make...

IOPS from RAID units by
davidhoffer
The IOPS the array can deliver is the aggregate of all the drives in the raid group less the hot spares and parity drives. Its more complicated than that of course but its a not bad rule of thumb. So 10 data drives that can each deliver 100 iops could (in theory) deliver 1000 iops when bound...

Multi microsd reader by
acd
micro-SD are one of the most economical and compact flash media.
I wonder if there are adapters to connect many of them in a compact
format,
say 32,64 or more.
This would represent a scalable SSD building block.
