That means even if 2 hard drive fail , you can do IO on this volume. As soon as HD's come back, the data will be healed automatically.<br></div><div>You will have 4TB of storage space while 2TB will be used for redundancy. You can have different number of redundancies like 4+1, 4+2, 8+4 etc.</div><div> <br></div><div>Ashish<br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Sham Arsiwala" <shamarsiwala@gmail.com><br><b>To: </b>gluster-users@gluster.org<br><b>Sent: </b>Tuesday, August 9, 2016 10:38:59 AM<br><b>Subject: </b>[Gluster-users] Need help to design a data storage<br><div><br></div><div dir="ltr"><div class="gmail_default" style="font-size:small">HI,<br><div><br></div></div><div class="gmail_default" style="font-size:small">I want to store data which is 135TB, and main requirement is data redundancy, i can scarify of data performance, but data should not be lost.<br clear="all"></div><br><div class="gmail_default" style="font-size:small">can you help me in a design</div><br>-- <br><div class="gmail_signature"><div dir="ltr"><div>-- <br>Regards.:<br>SHAM P.
