Key points to note on these 099T5J Dell 12G cards in IT-Mode:-
Small to medium business owners can enjoy the latest RAID technology at affordable prices and low power consumption with the Dell PowerEdge RAID Controller (PERC) H330. Ideal for file, web, database and email servers, the PERC H330 delivers trusted Dell PERC reliability with minimal maintenance effort.
The PERC H330 entry-level controller card offers a straightforward solution that includes essential RAID levels and support for non-RAID (passthrough) configuration options. In addition, the card connects to SATA and SAS hard disk drives, and solid state drives, allowing for tiered storage that optimizes cost and performance.
Physical disk power management (Dimmer Switch™) technology provides additional cost savings by managing power consumption for idle, unconfigured and configured drives. Dell’s entry-level RAID controllers cover the spectrum of tiered storage requirements for cost-sensitive applications that require robust data protection.
Tekmart caveat:-
For parity-based RAID (RAID5, RAID6, RAID50, or RAID60) it is essential for performance workloads to have controller cache present. Controllers with write cache are able to buffer large amounts of write I/O and have a hardware XOR engine for calculating parity.
Controllers without cache such as the H330 above must “Write Through” I/O directly to disk which hampers and slows overall I/O performance dramatically. While RAID5/50 is supported on the H330, the performance is considerably lower and similar to software RAID performance. Dell discontinued parity RAID (RAID5/50) support on the H345 controller.
For best performance with RAID5/6/50/60, Dell strongly recommends a RAID controller with controller cache and hardware XOR engine such as the H730P, H740P, H745 or the H840.
When choosing a storage controller, consider both your business’s storage and performance demands and needs as well as your budget:
- :: If you are configuring external storage enclosures with high-performance SAS hard drives and application-accelerating solid-state drives, consider the H840 for your Hardware RAID requirements or the 12Gbps SAS Host Bus Adapter to present disks in “Pass-Thru” mode to your application.
- :: If you are implementing hybrid server platforms based on solid-state storage for unsurpassed performance and enterprise-class reliability, our H740P and H745 are very good choices.
- :: If you are a small- to medium-business owner looking for file, web, and email servers at affordable prices and low-power consumption, the entry hardware RAID PERC H330 or H345 may be the right controller for you.
-
When choosing a RAID controller, there are a few critical hardware features that affect performance to keep in mind:-
- :: Controller Cache – There are two types of cache on Dell high performance controllers –
-
Write Cache & Read Cache.
-
- :: Write Cache can be configured in “Write Back” or “Write Through” modes. Write Back is the default setting and is specifically used for Hard Disk drive configurations. Write Back enables write I/O to complete more quickly providing better overall disk performance. With “Write Through” mode, the architectures of our low latency, high performance flash based SAS/SATA Solid State Disks are optimized for best performance.
-
- :: Read Cache can be configured to “Read Ahead” and “No Read Ahead”. HDDs are the main benefactor of Read Ahead and provides slightly better read performance.
-
- :: FastPath™ feature enables the use of the second core on the RAID-On-Chip (ROC) Processor to accelerate write-through I/O, which enhances SSD performance
