Re: StarWind iSCSI SAN Version 8.0 Beta

Are there any plans to include in V8 option to change L1 cache type and/or size 'on the fly'?

Re: How to choose exact time to create snapshot on CDP device?

My intention is to create "backup of backup". I'm using Windows Backup to create backups of Windows Server and the target is iSCSI disk. This happens about 10 PM. So I'd like to create snapshot of that backup volume on 5 AM. If, for example, my backup volume gets corrupted during next back...

How to choose exact time to create snapshot on CDP device?

During configuration of device I can choose period of 1440 minutes (that is, 1 day) but I don't how to make sure that snapshot takes place exactly at the chosen time. I've found no way to configure this (searched for that in 'StarWind.cfg' fil...

Re: Etherchannel vs Round Robin

I have RR policy over two NICs and I'm able to saturate both network cards bandwidth (except linux OS, but that's other story - this problem is not related to SW). My storage is DELL PERC H700 (512MB cache) and RAID50 (8x HDDs).

Re: Round robin iops policy - peculiar effect

Sorry all folks for late update but I forgot about it :) Problem has been (almost) solved with VMware support. Firstly I've been told that tests performed via SSH console on ESXi hosts using DD command are far from the proper way of testing storage performance. The one and only valid method is to te...

Re: Round robin iops policy - peculiar effect

OK, I`ve got two oquestions for now: 1.Would you be so kind to keep us updated about the progress of the solving the issue from VMware side? 2.Are you able to replace starwind for testing purposes to MS iSCSI target? Or maybe just add it if you have some additional server identical to the one where...

Re: Round robin iops policy - peculiar effect

Two screenshots presenting what is happening on iSCSI target during my tests. First one shows that starting dd on ESXi host B when ESXi host A is dding doubles number of IOPS. Both hosts are using RR policy. iSCSI_target_IOPS_RR.png Second shows what is happening when I changed MRU policy to RR duri...

Re: Round robin iops policy - peculiar effect

To be honest, for me it looks like you have specified only one NIC as destination on your ESX. Would you please doublecheck if both NICs on ESX are connected to both StarWind NICs and configured to use RR? Sorry for the late answer but was on holiday. I've checked connections once more as you sugge...

Round robin iops policy - peculiar effect

Hi I have two ESXi 5.0 hosts and one storage. Both ESXi hosts have 2 interfaces for iSCSI only and storage has 4. Every interface is configured to work in separate network segment. All connections are made using two separate HP V1910 (to get real failover) series switches without using jumbo frames ...

Re: Free edition license doubts

Anton, thanks for replying and clarifying things. I have also received message from Alex Satler stating clearly "you may use StarWind Free Edition in production environment". For the future please pay close attention to EULA content - IMHO it is quite important (for some of us at least :wi...

Free edition license doubts

Hi all I always thought that free edition of StarWinds' iSCSI target is allowed to use in production. But when I checked license.txt file (attached to V5.7 and V5.8 ) there stands: USE OF SOFTWARE: StarWind Free / evaluation software is provided for personal and internal use only and may not be used...
