Hello everyone,
I have a 13-bay (13x HDDs) HTPC / Media Server that I built and need to know which RAID setup will be best for me. I have already purchased the hardware (scroll to bottom of post for equipment). I understand this may be overkill, but I went with this card because of the 16 ports (need 13) huge cache, built-in hot swap so I can sleep at night and the SSD "upgrade" key that I'm connecting an Intel 320 Series SSD to (Will just tape it to my case). The BBU is great for those occasional brown outs too. All of this is worth my peace of mind for years to come IMO. Oh, and the 4 SAS to SATA cables are included which I know are pricey.
Let me tell you what I do with it so you understand my needs.
Tasks and objectives from the HTPC / Server:
- Streaming 1080p content to two (MORE IN FUTURE) different HDTVs at the same time.
- Record up to two ATSC/QAM shows at the same time with a dual tuner card.
- Torrenting
- Central backup unit that 3 PCs report to in the middle of night for Images and folder syncs.
- 3D Blu-Ray Player
- I use a SSD to keep my OS separated from the RAID array.
Questions:
Do I go with Raid 5, 6, 10, 50 or 60?Keeping the most possible storage space is highly preferable because I already have 8TB of just media, not including backups. However, I want redundancy. I plan on using the "Hot Swap" feature built-in to the card so in case of HDD failure, it will automatically replace the failed HDD. I am thinking RAID 5 or 6 is my best option. Am I correct or incorrect?
Can I do a relatively painless transition from 2TB HDDs I own currently (Seagate Greens) to 4TB HDDs (When available)? The card supports 3TB+, and I have UEFI BIOS.
RAID Equipment purchased:
Intel RS2WG160 PCI-Express 2.0 x8 SATA / SAS (Serial Attached SCSI) Controller Card $799 with cables
This is the exact same as LSI MegaRAID Internal 9260-16i that cost $930 without cables.
Excellent Performance, Highly Scalable: LSI SAS2108 ROC technology, x8 PCI Express Generation 2 host interface and 512MB on-board DDR II 800 MHz cache enhance the performance of mainstream applications. Capable of connecting up to 16 drives directly or up to 128 using SAS expanders.
Supports data redundancy using SAS or SATA hard disk drives through mirroring, parity, and double parity (RAID levels 1, 5, and 6), plus striping capability for spans (RAID levels 10, 50, and 60).
BBU Support: This adapter supports optional Intel Smart Battery AXXRSBBU7 or AXXRSBBU8 to maintain data in case the server or power fails, eliminating the need of an additional bulky power supply.
Hot Spare: Includes global hot spare support that automatically comes online to replace the first drive to fail on any array or disk group on the controller.
Intel RAID Smart Battery AXXRSBBU7 $169
This Intel RAID Smart Battery AXXRSBBU7 monitors the voltage level of the DRAM modules on the RAID controller. If the voltage drops below a predefined level, this Smart Battery switches the memory power source from the RAID controller to the battery pack. This battery pack provides power for the memory until the voltage returns to an acceptable level, at which time the Smart Battery circuit board switches the power source back to the RAID controller. Cached data is then written to the storage devices with no loss of data. This Smart Battery provides additional fault tolerance when used with an UPS.
Intel AXXRPFKSSD Activation Key $170
Uses solid-state drives (SSDs) as additional cache for the RAID controller by means of SSD flash tiering;
frequently accessed information is stored in cache to allow for rapid access
Accelerates SSDs using FastPath I/O, providing up to 465,000 I/O reads per second for small, random
block-size I/O activity; this is a dramatic increase over solutions that do not use FastPath
Thanks in advance
