Just wanted to share with you this new product from gblabs.com. We have tested SPACE a 16 Bay NAS connecting with 10Gig interface and it worked like a it works like a champ.
The box Supports 40 streams of DV, HDV, or DVCPro50 (80 with the addition of extra RAID card and a SPACE EX) and also Supports 12 streams of uncompressed SD, DNxHD 220/220x, ProRes 422(HQ) or DVCPro HD (24 with addition of an extra RAID card + SPACE EX). Isn't that cool?
My understanding was they use several different types depending on cable length requirements. The BIG difference between them and other players - no special tweaks on the client side. To get full 110MB/s on the client's GbE port, nothing needs to be done. I did a very crude file transfer test - not even direct but through two unmanaged switches - and got 110MB/s on a Z800 built-in GbE port on 4GB file transfer. No tweaks or adjustments at all.
They say the numbers are just outrageous on 10G connections: over 1GB/s on Linux, 700MBs Windows, 350MB/s OSX.
The "secret" sauce is their ability to pull data off the hard disks and pipe it into the NICs.
My understanding from our resellers is that this is an OpenE box. We sell openE on Mobile as well. OpenE only supports the 82598 chipsets out of the box because they use an old kernel (we get a special mod so we can support 82599 with receive side coalescing). That's why I was curious. It looks like they don't have it.
OpenE does a linux based storage stack for white boxes.
6 slot Linux PC with self contaned drive chassis (like SAN Networks, CI, etc).
2 native ethernet ports on motherboard
4 port 1Gig E ports on the PCIe card
By default SPACE is fitted with four 1G Ethernet (GbE) ports to which client workstations can be directly connected. However, for best performance with GbE clients we recommend that these GbE ports be channel bonded to a GbE switch, and client workstations connected to the switch. When used with a switch in this fashion these four GbE ports are optimised.
REPLY - gee, where have we seen this before ?
When SPACE is used in conjunction with a SPACE EX greater performance is available than could be derived by using the default four GbE ports. In order to make use of this extra performance for GbE clients we recommend fitting a 10GbE Ethernet card and using 10GbE connection to a GbE switch so that all available performance can be gained from the system.
SPACE has additional expansion slots that allow up to five further cards to be added. These slots can be used to increase the number of GbE clients that are directly connected to SPACE without a switch. Alternatively, they can be used to add up to ten 10GbE ports. These can be used to connect 10GbE client workstations that require greater performance than that offered by a GbE connection either directly or indirectly via a 10GbE switch. The expansion slots can also be used to add additional Raid cards to support more SPACE EX units and increase speed further.
I dont' see any specifics on what cards they are using.
if you look at their wiring diagram, and blow it up, you will see that they are using a D-Link DGS-3627 24 Port Gb stackable swithc with 3 10Gb slots. Our friends in Irvine are using this switch too.
So my money says that this is their 10Gig 2 port card -
There is many ways SPACE can be configured.
These cards can be added to the SPACE
Quad Copper 1Gb PCIe Ethernet card
Dual Channel Copper 10Gb PCIe Ethernet card (CX4) up to 5 HCA
Dual Channel SFP+ 10Gb card with 2 x LC optical SFP's (up to 50M range)
1- Use the included 4 port GbE using Link aggregation on a switch then connect Client systems to the switch.
2- Use up to 5 10Gb dual port HCA and connect each client to one port.
3- Use the existing 4 Port GbE and connect each client directly without a switch.
4- Also there are options in the web GUI for link aggregation which
I have not tested yet.
Test Results on a Space Mini with a single GbE I have connected 4 workstations and started transferring big chunks of files from all 4 workstations simultaneously and network monitor was showing 110~120 MB/s on each of the clients.
One other cool feature they have is called SPACE Echo which can be used for mirroring and redundancy, very promising product.
