Configuration of storage:
IBM V7000 gen2+
10x SSD 4TB
Interface 10GBe (iSCSI)
Dedicated card for compression
Configuration of test VM
2CPU, 4GB RAM
Linux Debian on ESX 6
Datastore mapped to ESX
Better IOPS during read operation and only a little lower on write. CPU usage for compression 30%.
Without compression:

FC target configuration - Targetcli as open source SAN (debian)
Installation on debian wheezy with kernel 3.10.25
Download rpm
apt-get install targetcli
Or install without recommended packages
apt-get install --no-install-recommends targetcli
Create file for datastore
dd if=/dev/zero of=/opt/test1 bs=1024 count=6000000
targetcli
Create datastore on targetcli
cd backstores/fileio
create itest1 /opt/test1 6144000000B
Create iSCSCI target instance
cd /iscsi
create
Map LUN to datastore (based on FILEIO)
cd luns
create /backstores/fileio/itest1
Configure ACL (check WWN in openiscsi section)
cd ../../acls
create
create iqn.1993-08.org.debian:01:dcb3d359cc91
Save configuration
cd /
saveconfig
Disable athentication
cd iscsi/
set set discovery_auth enable=0
cd /iscsi/iqn.2003-01.org.linux-iscsi.sc-azl-001.x8664:sn.8b4b5e8c13a2/tpgt1
set attribute authentication=0
Configure interface
cd portals
create
cd /
saveconfig
All config should looks like:
targetcli

OpeniSCSI installation - client (initiatior)
aptitude install open-iscsi
/etc/init.d/open-iscsi restart
Search target name:
iscsiadm -m discovery -t sendtargets -p 192.168.42.135
Check your initiator name
cat /etc/iscsi/initiatorname.iscsi
## DO NOT EDIT OR REMOVE THIS FILE!
## If you remove this file, the iSCSI daemon will not start.
## If you change the InitiatorName, existing access control lists
