Hi everyone, My main SAN is built around 2 x Brocade 48000 directors - 6 x 32-port cards per chassis. Whilst Brocade's documentation is very helpful on e.g. grouping connections on ASICs to avoid traversing the backplane - and saving a whopping 1600 nanoseconds into the bargain :-) - it has...

Hi, I am trying to list all devices and all information about each fibre channel device connected to an Emulex HBA on Windows eg. Make, Model, Type of device (disk, tape drive...). HBAnywhere does list the WWN but nothing else except the relevant Windows device name. What I am after is similar to...

Hi NG, I need to attach a storage device to freebsd servers. Rather than using a classical san solution with maybe netapps i heard of isilion with their nas solution. most important for me is simplicity in use, iops/throughput and scalabilty and flexibility when it comes to increasing the storage...

Hello, I have a problem to loose data on two Expansion units (StorageTek 2501) connected to the above mentioned controller - due to power up first the controller and after it the 2 trays. This is exact the reverse order it should be done - not giving the chance for the controller to...

This is a tough one to describe and ask help for, I know. I apologize. I have a relatively new Sun StorageTek 6540 RAID. When purchased we only bought four trays of storage, 300GB 15,000RPM disks. We set up all the hosts via a director class Brocade SAN switch (5300 I think). Ever since I...

hola ffolks: i looked everywhere online as well as in SPC-3 from T10/T11. fyi, T10 has now restricted access to T10 drafts for members only. i found that the same drafts are available from T11. 8-) ^Google^ is your magical friend. ;-) so, if an Array says that it provides Implicit ALUA support...

Now I can see a change coming. I know a guy, who is going into business by himself. He has built (with little help) a box under his desk with 4 Magny Cours, 128 GB RAM and 28 TB of raid (plus a SSD of 256 GB). This would be sufficient to run small projects. He claimed it has faster...

For those interested in, some Java/JavaScript code available under Tomcat5 and Tomcat6 enabling you to interrogate your SAN equipment using the WBEM protocol and a Web browser such as but not limited to Firefox or Internet...

Hi, I have a server which has an Adaptec SCSI Card 29160 installed; it has an "old-style" 68-pin HD connector. Supposing I need to connect it to an HP StorageWorks 60 Modular Smart Array, which only offers SAS connectivity... is there a way to do it, maybe through some intermediate device? I doubt...

I just tried some SEagate barracuda 2TB LP drives on some Adaptec 2420SA sata II raid cards. No dice. the adaptecs are running the latest 5.2.whatever firmware. they see the seagate drives, the firmware rev, the capacity (1800GB) but say the drive is not responding.

Under latest Linux such as CentOS 5.3. Will ICh10R give slightly better performacne than mdadm?

HP has a new RAID array that allows SATA host connections named the MSA2000 (there are options for iSCSI and Fibre Channel host attachment as well). Does this product allow more than one host to attach to the array? Can you attach an MSA50 2.5 SAS drive array to the MSA2000? HP...

Before I buy such one I really need to be sure that I can have encryption on this device. I want to use it to store my personal backup at a remote side. Is it possible to do a rsync (with SSH) from my CentOS box to the ReadyNAS box where I store my files on an encrypted partition or alike? Note...

Hi everyone, I have interfaced a Micro SD card to a MSP430 microcontroller using the SPI mode. Everything worked perfectly fine but I recently had problems when writing too often into my files. Here is my setup. As I said the card (SDHC 4Go) is directly connected to the microcontroller via its...

Is there any development KIT for me to upload or improve FTL resident in SSD ? For example, I'd like to devise a wear-leveling algorithm and equip it to a real SSD, not to a simulator. Thanks in advance.

Hi.everyone... Fujitsu Eternus 3000 Model 50 is running in our company. two controller units are installed. One controller unit is failed. I purchased new controller unit but don't know how to replace the controller unit 1) It's possible that the controller unit is replaced in online ? 2) After...

Does anyone yet make a TB Flash memory in a 3.5" drive physical format. If so, could you pass on a reference? The interface would need to support about at a 400MB/s sustained rate. I can work with any interface such as Fiber Channel or whatever . thanks for any tips

I am trying to find an 8bay (minimum) storage tower that doesn't take up a ton of space *and* doesn't cost a fortune. The best option would be a minimally sized self contained box like a via box I read about (but can't find for sale) (http://www.mswhs.com/2009/10/via-nsd-7800- review/) The second...
