Adaptec SCSI RAID 2230SLP Controller, RAID 0, 1, 5, 10, 50, JBOD Advanced performance and flexibility for entry-level to mid-range servers
I had an experience with SCSI raid-5 controller when I was in charge in managing a bunch of critical data servers in a mining company. All the servers are mid-range type business-class servers with SCSI Raid-5 configurations. One of the servers was beeping loudly when I got into the server-room to replace the backup cartridges of the autoloader backup system. I found that one of the SCSI hard-disks failed. Fortunately I found that all the production systems were running well, no problem at all. But I had to work out to resolve the faulty disk to prevent any possible further damage even though the production system was not affected.
I had the organization ‘IT Operation Manual’ document and found the SOP to handle such situation. And the good thing was that I had a couple of SCSI disks backup for replacement. Thanks to the servers hot-plug system which allowed me to replace the faulty disk without the need to shutdown the system. In Raid-5 SCSI-disks configuration and with the hot-plug capable system, replacing the faulty disk while the system is running is possible. Make sure that all your critical servers support hot-plug feature and configured with Raid-5 controller to prevent the operation of business disruption.
In raid-5 disks volume configuration, you require a minimum of three hard drives where two hard-drives are used by the system to write the data while one hard drive is used for parity information. However, all the data and parity are moved across the disks. The advantage of the raid-5 configuration is fast in reading but slower in wiring. Critical servers are typically configured with SCSI Raid-5 system with more than 3 SCSI hard-disks configuration. Generally the mid-range servers are designed to support up to 6 pluggable disks or even more.
In Raid-5 system, with the total number of the disks in the raid configuration – you can get total volume space equal to the total number of the disks minus one. For example, if each of the SCSI disk has 100 GB space capacity, with 6 SCSI disks in Raid-5 configuration you will get 500 GB space capacity which is (6-1) x 100 GB.
Adaptec SCSI RAID 2230SLP Controller
One of the Raid controllers available in the marketplace is Adaptec SCSI RAID 2230SLP two-channel Controller. This controller supports Raid-5 as well as Raid 0,1,10, and 50. And the advanced features the adapter support is full capacity utilization of mixed size drives. This Raid-5 controller is very fast provides data transfer rates up to 320 MB/sec on each channel performing large data transfers or connecting many drives on a single channel.
For critical data servers including databases, exchange, and other file servers, make sure you purchase the server that supports hot-pluggable SCSI disks and supports Raid 5 Controller for high-performance storage and high-availability system such as HP ProLiant DL380 G6 Base – Server series. DL380 supports Serial Attached SCSI (SAS) with up to sixteen (16) SAS drives and new embedded Smart Array RAID controllers, you get quicker access to data and increase storage bandwidth for cutting edge storage performance.
