Hi, I am investigating how to create a high-availability iSCSI SAN. I have investigated Intransa and Equallogic iSCSI SANs and EMC and other Fiber Channel SANs, but they are all way to expensive. Especially iSCSI which I expect to undergo many changes and improvements in the coming years making my...

My department is in need of 2 terabytes of storage space for archiving image files. The image files must be available on-line to our customer support agents (24x7). However, the files are accessed infrequently. So, IDE RAID seems to be a perfect choice. Right now, I have two possible IDE...

Hi, I want to know how I can find out whether a host HBA is connect to a storage device through a switch or it is connected directly. Tia --Upendra

I am just doing a project using a embed cpu to read and write a NAND FLASH.The cpu is 400MHz,and the bus is 100Mhz.but I find when I read the FLASH£¬I can only get the speed of 1kbyte/s.It is very strange.I want to know whether there are something I didnot pay attention to.so I need...

We are looking to 'attach' a cd changer in an office to a server in our datacenter. This will be used to copy cd data to a SAN. I have heard this can be done, but don't know how. Can anyone point me in the right direction? Can we use FCIP or iSCSI to do this? Thanks Ken

Hi, I'm designing an embedded ATA controller that supports UDMA operation. I've found something in the T13 specs that is causing headaches. They seem to require that the host read the status register after issuing a "Read DMA" or "Write DMA" command. Furthermore, it seems to suggest that...

We are currently observing tape media errors during our nightly backup runs. Backup server is a SGI 02, external Sony AIT tape drive. We started with AIT-1 (Sony SDX-300C) three years ago, 10 Sony SDX1-25C tapes reused 4 days a week, 8-23GB per tape run (amanda, backup data go to local disk first...

Let me preface this with I'm an undergraduate at the University of Delaware, majoring in computer engineering. I am currently using an FPGA development board, and one of my tasks is to implement a memory check of the board's DDR SDRAM by writing and reading from the device's entire address space...

I have a Dell Win2k NAS connected via an emulex hba and a Brocade switch to an NEC SAN. I'm storing lots of small files and folders on a 14 disk raid 10 set within the san. The disk load that I see is about 60% write & 40 % read. Everything runs well and performs as expected, but intermittently...

I've been trying to add two disk packs currently on the shark to one of the intel (windows) servers. I have defined each disk pack as a raid 5 individually. I couldn't find a way to raid the two disk packs together. Then I tried to add the volumes to the intel server. The volumes were added...

Hi, As I've posted in the last several weeks, I've been working with an EMC CX700 recently, and I think that I have somewhat gotten the basics down, but I've encountered something rather strange (to me anyway). We have 6 servers in a test environment, all with dual-port QLogic HBAs. Right now,...

I got Acronis TI last month and installed it on my laptop (I downloaded the latest upgrade patch as well, so I'm running the latest build - I think its 613). I ran a full backup of my C: drive (Windows XP Home Edition) at that moment, and restricting the TIB file size to 700MB to fit on a CDR. The...

I had a question on the support of Snapshot technologies on Windows. EMC has something called Symmetrix Integration Utility (SIU) on Windows which is necessary for creating consistent copies of the production data using TimeFinder. They say this utility is required to unmount volumes and lock it...
