--_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I'm just setting up some storage for use with oVirt and am wondering why I = might choose glusterfs rather than just exporting a raid array as iscsi. T= he oVirt team seem to be pushing gluster (though that could just be because= it's a Red Hat product). Can anyone answer this one? What I have come up with is as follows. For: - easy to expand - redundancy across storage devices/easy replication - high availablility - performance - it's kind of cool :) - maintenance? Against (these are guesses): - performance? (multiple layers of filesystems everywhere - fs in = vm + image on gluster + gluster + block filesystem) - complexity - maintenance? Any help here is appreciated. Also, does the underlying block level filesy= stem matter here? VMs running under ovirt would be typical business applic= ations - file serving (samba4), email, databases, web servers, etc. Cheers, Justin. --_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"><head><meta http-equiv=3DContent-Type content= =3D"text/html; charset=3Dus-ascii"><meta name=3DGenerator content=3D"Micros= oft Word 15 (filtered medium)"><style><!-- /* Font Definitions */ @font-face {font-family:Wingdings; panose-1:5 0 0 0 0 0 0 0 0 0;} @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0cm; margin-bottom:.0001pt; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-fareast-language:EN-US;} a:link, span.MsoHyperlink {mso-style-priority:99; color:#0563C1; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:#954F72; text-decoration:underline;} p.MsoListParagraph, li.MsoListParagraph, div.MsoListParagraph {mso-style-priority:34; margin-top:0cm; margin-right:0cm; margin-bottom:0cm; margin-left:36.0pt; margin-bottom:.0001pt; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-fareast-language:EN-US;} span.EmailStyle17 {mso-style-type:personal-compose; font-family:"Calibri","sans-serif"; color:windowtext;} .MsoChpDefault {mso-style-type:export-only; font-family:"Calibri","sans-serif"; mso-fareast-language:EN-US;} @page WordSection1 {size:612.0pt 792.0pt; margin:72.0pt 72.0pt 72.0pt 72.0pt;} div.WordSection1 {page:WordSection1;} /* List Definitions */ @list l0 {mso-list-id:913467833; mso-list-type:hybrid; mso-list-template-ids:-1938410588 947050786 201916419 201916421 201916417 = 201916419 201916421 201916417 201916419 201916421;} @list l0:level1 {mso-level-start-at:0; mso-level-number-format:bullet; mso-level-text:-; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:"Calibri","sans-serif"; mso-fareast-font-family:Calibri; mso-bidi-font-family:"Times New Roman";} @list l0:level2 {mso-level-number-format:bullet; mso-level-text:o; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:"Courier New";} @list l0:level3 {mso-level-number-format:bullet; mso-level-text:\F0A7; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:Wingdings;} @list l0:level4 {mso-level-number-format:bullet; mso-level-text:\F0B7; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:Symbol;} @list l0:level5 {mso-level-number-format:bullet; mso-level-text:o; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:"Courier New";} @list l0:level6 {mso-level-number-format:bullet; mso-level-text:\F0A7; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:Wingdings;} @list l0:level7 {mso-level-number-format:bullet; mso-level-text:\F0B7; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:Symbol;} @list l0:level8 {mso-level-number-format:bullet; mso-level-text:o; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:"Courier New";} @list l0:level9 {mso-level-number-format:bullet; mso-level-text:\F0A7; mso-level-tab-stop:none; mso-level-number-position:left; text-indent:-18.0pt; font-family:Wingdings;} ol {margin-bottom:0cm;} ul {margin-bottom:0cm;} --></style><!--[if gte mso 9]><xml> <o:shapedefaults v:ext=3D"edit" spidmax=3D"1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext=3D"edit"> <o:idmap v:ext=3D"edit" data=3D"1" /> </o:shapelayout></xml><![endif]--></head><body lang=3DEN-AU link=3D"#0563C1= " vlink=3D"#954F72"><div class=3DWordSection1><p class=3DMsoNormal>Hi,<o:p>= </o:p></p><p class=3DMsoNormal><o:p> </o:p></p><p class=3DMsoNormal>I&= #8217;m just setting up some storage for use with oVirt and am wondering wh= y I might choose glusterfs rather than just exporting a raid array as iscsi= .
