As the perfect complement for Intel’s SAS-2 generation RAID cards, this twenty-four port expander card offers ultimate flexibility for architecting a high drive count (greater than 8 drive) storage solution in any sized system. The low profile height enables simple installation into a 1U or 2U system with a low profile chassis cutout. In addition, the MD2-compliant depth (6.6") fits in motherboards with heat-sinks that would interfere with longer add-in cards. In cases where an add-in slot is not available, the Intel RAID Expander Card RES2SV240 can even be mounted to a chassis wall or air-duct.

  • newegg Excellent Performance Overall performance of the RES2SV240 is on par with Intel’s SAS-2 high port count RAID with transfer rates of up to 6Gb/s per port. While today’s high port count RAID cards typically include an expander on the card, a RES2SV240-based solution separates the expander from the RAID card for more system design flexibility.
  • newegg Low-cost Alternative to High Port Count RAID Cards Provides a more economic solution that is similar to a 16 or 20 high port count card, but has more flexibility as the RES2SV240 can be teamed up with a wide variety of 4 or 8 port SAS RAID card/modules to offer features that are best suited to customer needs.
  • newegg Inside-the-box Design Flexibility With a true MD2 form factor, this expander card is ideal for low-profile height and half-length adapter slots. In addition, the card design allows for mounting on chassis walls or ducting. Power can be obtained either from a PCIe slot or a power cable.

4 out of 5 eggs

Pros: Just plain works! All cables included! Connected to and LSI 9207-8i controller and getting 540+mb/s using all ports. Tested it with two older Highpoint RocketRaid cards I had laying around (2720sgl & 2680) surprisingly worked with both without hiccups! (Transfer speeds were lower than the LSI)

Cons: None so far.

Other Thoughts: This is not a controller!!! You need a raid card to connect to this... seems complaint to everything!

5 out of 5 eggsFunctions and negotiates SATA3/SAS2

Pros: Connected to an Areca 1882ix-12
Works perfectly.
No irregular behavior observed from any of the disks. Routine array checks of over 20hours go through with no errors.
No other explanations are necessary as this is a SAS card that does its job correctly.

Cons: Absolutely none.

5 out of 5 eggsWorks perfectly with my LSI 9270 controller and Chenbro CK23601 Expander

Pros: Compatible with Avago LSI 9270 (LSISAS2208) host controller upstream
Compatible feeding a Chenbro CK23601 expander downstream
Can input from a single SAS channel
Can input from dual SAS channels
Almost no heat generated
Mounts in a PCIe 4X slot for power (power-only no signals)
Can be power from a Molex 4-pin as well (my use)
Arrays survived re-routing from Chenbro expander to this Intel expander

OS version and host controller drivers should play no role in how well controller and expanders work together. This technology is 100% hardware and no software comes into play.

Cons: None, all works as expected

Other Thoughts: I have been wanting to try this expander for a while as I have only used Chenbro in the past. I bought from the auction site, not from NE.

I just got a RES2SV240 expander and am using it along side my Chenbro CK23601 expander, on my LSI 9270-8i controller - 9270 --> RES2SV240 --> CK23601. I am using both 8087 SAS output channels from my controller to the frist two of the 8087 input channels on the Intel RES2SV240. I then use 1 8087 output channel from the Intel RES2SV240 to my Chenbro CK23601 Expander (feeding 28 Seagate 4TB HDDs drives, 2 14-drive arrays at R6) and I use the remaining 3 8087 output channels on the RES2SV240 for my SSD arrays (Crucial MX100 and Samsung 850 Pro SSDs).

Using the 2 channels from the controller to Intel Expander lets my SSD arrays attached to the Intel expander utilize the full 2-channel bandwidth with the LSI controller, when needed. The 28 drives on the Chenbro are of course flowing through one channel from the LSI --> Intel --> Chenbro, but spinning drive arrays use little bandwidth (~800MB/s 14@R6) relative to SSD arrays (~2GB/s 4@R0, ~1GB/s 2@R0).

I am running 28 HDDs and 12 SSDs all attached at 6GB/s (SATA3) speed. No issues. All my arrays survived the re-routing from Chenbro to and through the Intel. My Chenbro expander gets very warm even with the attached fan but this Intel barely gets warm and is about 60% the size of the Chenbro.

If new to SAS expanders, realize that at least one of the 6 SAS channels (SFF-8087) will be used as input from a host controller, this leaves at most 5x4=20 possible drive connections. If you use Dual/2 input channels from the host adapter you will have only 4x4=16 possible drive connections, but the possibility of using both input channels for throughput (only SSDs could utilize the throughput of both channels). I believe the logic is that once 1 channel is used up, traffic spills over to the 2nd channel.

You can of course cascade/daisychain to other expanders, supporting drives up to the max limit supported by the controller. My usage shows that a Chenbro expander can be feed from this Intel expander. This is good to know as few mention this anywhere.

Many don't like the fact that a 6-connector/24-port expander can only support 5 SAS output channels (so 5x4=20 directly attached drives). This is simply the way the total ports are counted. Ethernet switch ports are counted the same way, as something is usually (but not required) feeding the switch from upstream. A SAS expander is simply a SAS switch, routing commands from a host controller to target IDs. You can even buy SAS expanders mounted in a box, and fed by SFF-8088 cables (the external version of the SFF-8087 connector).

The RES2SV240NC model comes with no 8087-8087 cables, in case you have your own.

I hope you found this info helpful. Rarely have I see this info online.

5 out of 5 eggsAmazingCard

Pros: It just worked. I have an ESXI VM with passthrough to a IBM M1015 card. Adding this card to the mix required 0 software changes on my part.

Cons: As others have noted, the 'installation guide' is a joke. I guess the thought process is if you buy a card like this, you most likely know what you are doing. Not worth losing an egg over.

Other Thoughts: Improved installation guide for a IBM M1015: Use one of the provided SAS to SAS cables to connect the SAS slots closest to the bracket on this card and the M1015. Use the other slot on the m1015 and the 5 remaining slots on this card to connect 24 drives using those SAS to 4xSATA cords. (1+5)x4 = 24. Math.

One of the reviews suggests that thing overheats. I preemptively through a COUGAR CF-V12H at this thing.

5 out of 5 eggsExactly as advertised

Pros: Plug 'n Play , no headache.
Using with a 3Ware 9550 raid card. No issues, no problems. It just works.

Cons: They could some instruction card with the device. I wasn't sure if I had to plug into motherboard or not - had to look it up.

1 out of 5 eggsIt does what it's supposed to but...

Pros: - supposed to expand your controller's drive hosting capabilities

Cons: - the instructions are terrible
- out of the box it didn't work

Other Thoughts: The instructions explain how to install the device into your motherboard in but it doesn't explain how to connect it to your SAS card with enough detail. The diagram has a lot of arrows and boxes of text, but it's not at all technical. You receive two short SAS cables which you expect to go between the expander and the controller, but the guide doesn't say to connect one or two if you're going to two hotswap backplanes. When the unnit doesn't work, calling Intel is useless as their overseas technical support representatives aren't so technical and their advice when things don't work is to flash upgrade your hardware. "Does this device even have a flash upgrade?" "I don't know... let me check." That certainly gives me confidence.

I suggest utilizing a controller from a manufacturer with more than two ports if you need more than 8 drives expanded.

5 out of 5 eggsSolid Expander

Pros: This expander has been working solidly in my storage server for several months helping to server up iscsi to my esxi hosts. Note as other have mentioned this doesn't have any controller capabilities. The main reason I'm writing this review is I have an Areca 1880xi and I couldn't confirm it would work with this would work with my Raid card.

I heard of people running into difficulties with some Areca cards and this expander especially if the have other expanders in the unit. In those cases their raid cards will not pick this expander up. That said, I have run into no issues.

My raid card info:
Firmware/Bootrom version: V1.51 2012-07-04

Cons: None that I can think of.

3 out of 5 eggsUnit failed after 2 months

Pros: Unit worked as expected...very fast, no drama. 3 stars for quick failure...would have give lower, but it works so dang well...hoping my failure was just a fluke.

Cons: Units runs hot. Failed after 2-3 months usage. Seeking RMA. This is even after I installed a small fan blowing on the heatsink to ensure adequte airflow.

Other Thoughts: Using on a Windows server with LIS 6870-4i card to increase the number of ports. Running 8 drive RAID 6 array (does not include 2 hot swap drives) - heavy/near constant IO. Also running online backup with 4 drive RAID 5 array. Offline backup of 3TB drives. Users are media editors. Power supply is 700W unit. 16GB ram, i5 processor.
