By using SVM (or zfs) to create a RAID volume you will be using software RAID, so no need for fancy hardware. If you use hardware raid then you don't need SVM or anything like it, the OS just sees it as "a disk" and shouldn't care what kind of mirroring or data protection is going on.
By definition you will be using extra space if you use RAID5, but that is the price you pay for having your data protected.

I have this setup, i can only find docs to unmirror a raid 1 set, how do you get rid of a raid 5 set? the same way? metadetach and metaclear?

Hi,
We have a Sunfire 4150 with On-Board Internal Raid Controller connected to 4 X 146 GB SAS disks.
This also has an External Raid Controller (Storagetek Eight-Port, External HBA
Model SG-XPCIESAS-R-EXT-Z) connected to a JBOD array ( Storagetek XTA2530 ) which has 5 X 300 GB Hard disk.

Hello,
I am using Red Hat 2.6.23.1 with RAID 6 controller (card).
(When I use "cat /proc/partitions" I do not see the separate HDDs in the RAID, I see one drive for the RAID itself, as it is considered 1 large drive.)
I used a "dd" check to test my RAID drive speed and found it was a bit slow,... (7 Replies)

PREDEFINED CONSTANTS
SVM CONSTANTS
o SVM::C_SVC -The basic C_SVC SVM type. The default, and a good starting point
o SVM::NU_SVC -The NU_SVC type uses a different, more flexible, error weighting
o SVM::ONE_CLASS -One class SVM type. Train just on a single class, using outliers as negative examples
o SVM::EPSILON_SVR -A SVM type for regression (predicting a value rather than just a class)
o SVM::NU_SVR -A NU style SVM regression type
o SVM::KERNEL_LINEAR -A very simple kernel, can work well on large document classification problems
o SVM::KERNEL_POLY -A polynomial kernel
o SVM::KERNEL_RBF -The common Gaussian RBD kernel. Handles non-linear problems well and is a good default for classification
o SVM::KERNEL_SIGMOID -A kernel based on the sigmoid function. Using this makes the SVM very similar to a two layer sigmoid based
neural network
o SVM::KERNEL_PRECOMPUTED -A precomputed kernel - currently unsupported.
o SVM::OPT_TYPE -The options key for the SVM type
o SVM::OPT_KERNEL_TYPE -The options key for the kernel type
o SVM::OPT_DEGREE -
o SVM::OPT_SHRINKING -Training parameter, boolean, for whether to use the shrinking heuristics
o SVM::OPT_PROBABILITY -Training parameter, boolean, for whether to collect and use probability estimates
o SVM::OPT_GAMMA -Algorithm parameter for Poly, RBF and Sigmoid kernel types.
o SVM::OPT_NU -The option key for the nu parameter, only used in the NU_ SVM types
o SVM::OPT_EPS -The option key for the Epsilon parameter, used in epsilon regression
o SVM::OPT_P -Training parameter used by Episilon SVR regression
o SVM::OPT_COEF_ZERO -Algorithm parameter for poly and sigmoid kernels
o SVM::OPT_C -The option for the cost parameter that controls tradeoff between errors and generality - effectively the penalty for
misclassifying training examples.
o SVM::OPT_CACHE_SIZE -Memory cache size, in MB
