			<content:encoded><![CDATA[<p>I got this forwarded to me from a friend, who got it from a friend, who has a relative working at NASA: </p>
<blockquote><p>Although we remained hopeful he would wake up and fly away, the bat eventually <span style="-webkit-text-stroke-width: -1;">became IPR 119V-0080 after the ICE team finished their walkdown.  He did change the direction he was pointing from time to time throughout countdown but ultimately never flew away.</span></p></blockquote>
<blockquote><p>IR imagery shows he was alive and not frozen <span style="-webkit-text-stroke-width: -1;">like many would think.  The surface of the ET foam is actually generally between 60-80 degrees F on a day like yesterday.  SE&amp;I performed a debris analysis on him and ultimately a LCC waiver to ICE-01 was written to accept the stowaway.  Lift off imagery analysis confirmed that he held on until at least the vehicle cleared to tower before we lost sight of him.</span></p></blockquote>
<blockquote><p><span style="-webkit-text-stroke-width: -1;">And thus is the legend of the STS-119 Bat-ronaut.</span></p></blockquote>

			<content:encoded><![CDATA[<p><a href="http://elemental.org/">mercury.elemental.org</a> is the server which hosts my $HOME and this website. It&#8217;s my Solaris 10 play-box, and I guess you can say that maintaining it is something of a hobby.</p>
<p>Its hardware is a quad core Xeon-equipped Dell PowerEdge 860, a small 1u server. Its pair of internal drives are Seagate SATA2, and were connected to the on-board Intel ICH7-based SATA controller. But there was something fishy about this in that the Solaris <a href="http://docs.sun.com/app/docs/doc/816-5177/ahci-7d?a=view"><em>ahci</em></a> SATA driver never attached to it and instead the drives ran in IDE mode. Despite my best efforts, I couldn&#8217;t change this. I eventually found out the reason &#8211; Dell crippled the SATA controller in the system BIOS to allow only IDE mode!</p>
<p>So this server was sold with &#8220;SATA drives&#8221;, which would imply a fully functioning SATA controller to drive them&#8230; but not quite. IDE mode means there were no benefits of SATA NCA and other niceties. </p>
<p>To fix this, I got a <a href="http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/lsisas3041er/index.html">LSI SAS3041E-R</a> controller &#8211; a 4x PCIe card that uses the <a href="http://www.lsi.com/storage_home/products_home/standard_product_ics/sas_ics/lsisas1064e/index.html">LSISAS1064E</a> chipset and offers 4 SATA ports. In Solaris land, this card would be driven by the <a href="http://docs.sun.com/app/docs/doc/816-5177/mpt-7d?a=view"><em>mpt</em></a> driver, a proven driver as the LSI SAS 1064 and 1068 chipsets are used to drive the on-board hard drives in pretty much every current Sun x86 and Niagara-based SPARC systems.</p>
<p>I installed this card in the single 8x PCIe slot in the PE860, and ran a 24&#8243; SATA cable from it to HDD1, and used the existing Dell cable that connected the on-board controller to HDD1 to connect HDD0 to the card. After some fiddling in <em>/boot/solaris/bootenv.rc</em> to tell the kernel the new device path to its boot drive, the <em>mpt</em> driver attached and I was good to go.</p>
<p>I kicked off a SVM mirror resync as a basic test of sequential IO, and I hit 75MB/s reading from one drive and writing to the other. Not bad. A <em>zpool scrub</em> of my mirrored ZFS pool of 66.5GB of data (pool is 444GB in size) took just over an hour.</p>
<p>So if you&#8217;re thinking about a 4 or 8 port SAS/SATA card, consider the <a href="http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/basic_connectivity/index.html">LSI SAS3041 or SAS3080/3081</a> cards, respectively. Both come in PCI-X and PCIe flavors and are supported by Solaris (and <a href="http://opensolaris.com/">OpenSolaris</a>) just fine. </p>

<p>I&#8217;d like to take a different approach with this review, one that descends below the GUI to highlight aspects that server administrators in particular would be more interested in.<br />
<span id="more-125"></span><br />
OpenSolaris is just a few months old now, with its first version being 2008.5, released two months ago. Since then, Sun engineers and community members alike have been making bi-weekly updates to its various components (currently at build 93) in preparation for the next full release, 2008.11. One who has a OpenSolaris 2008.5 installation may track these intervening builds as they become available using the <a href="http://opensolaris.org/os/project/pkg/">Image Packaging System</a>&#8217;s update features. Haters of SVR4 package management rejoice.</p>
<p>Before I begin, I&#8217;m going to assume that you, the reader, have already heard plenty about the big, oft-quoted features such as <a href="http://opensolaris.org/os/community/zfs/">ZFS</a>, <a href="http://opensolaris.org/os/community/dtrace/">DTrace</a>, and <a href="http://opensolaris.org/os/community/smf/">SMF</a>. If you haven&#8217;t, get on over to those links and read up as you&#8217;re missing out on some really good stuff. If you have, I&#8217;ll show off some compelling new sub-features of those systems, as well as other, unrelated ones. So sit back and read along and try this stuff out when you&#8217;re done!</p>
<p><strong>OpenSolaris Is A Storage Multi-Tool</strong></p>
<p>This preview focuses on the new storage-related components of OpenSolaris. This is a category that has received quite a bit of attention over the past two years with many new components being integrated into the OS.</p>
<ul>
<li><strong>ZFS.</strong> Prior to the availability of ZFS, Solaris was pretty much on-par with the built-in storage management features of peer OSes, with advantages in some areas of storage management (multipathing and fibre channel) and deficiencies in others (UFS and LVM were getting tough to manage in ever-growing, multi-TB environments.) The inception and inclusion of ZFS drastically improved the situation and brought the concept of storage management to a level of capability and availability (free!) that the industry had yet to see.But don&#8217;t think that the designers of ZFS took a break from the action.
<p>ZFS as it exists in OpenSolaris sports major performance improvements and several additional features of note:</p>
<ul>
<li><strong>GZIP Compression.</strong> GZIP compression may be applied to a ZFS filesystem of ZVOL in addition to the original LZJB scheme. GZIP compression offers better compression ratios when compared to LZJB, but at a higher cost in terms of CPU power needed. If the best compression possible is required and CPU capacity is not an issue, this new compression method will make you happy.</li>
<li><strong>Case Insensitivity.</strong> One may set a ZFS filesystem to operate with no regard to the case of file names, a la Windows NTFS/FAT and default Mac OS HFS filesystems. This feature was added in conjunction with the new CIFS server (see below).</li>
<li><strong>Autoreplace.</strong> This is a new property of a zpool, which defaults to &#8220;off&#8221;. What it allows you to do when set to &#8220;on&#8221; is if a drive in a zpool dies and is subsequently pulled and replaced, ZFS will detect this and automatically bring it back into the pool and do what it needs to do with it to restore the pool to an optimal state. When left in the default state, manual intervention after the drive replacement is required.</li>
</ul>
</li>
<li><strong>Easy iSCSI.</strong> One of the first big feature adds after ZFS went GA is the ability to easily create LUNs for export via <a href="http://docs.sun.com/app/docs/doc/819-2240/iscsitgtd-1m?a=view"><em>iscsitgtd</em></a>. Now, remember that <em>iscsitgtd</em> serves out block devices, not filesystems, so one must create and use raw ZVOLs that get their own device entries in <em>/dev/zvol/&#8230;</em> so that they can be treated like any raw disk device. After creating a ZVOL, exporting it out via iSCSI is as simple as:<br />
<code>zfs create -V 256G pool/my/zvol<br />
zfs set shareiscsi=on pool/my/zvol<br />
- or do it in one command -<br />
zfs create -o shareiscsi=on -V 256G pool/my/zvol</code><br />
You can also create LUNs that are hosted on UFS, or any other supported filesystem for that matter. Management of the iSCSI LUNs presented by <em>iscsitgtd</em> is accomplished via the <a href="http://docs.sun.com/app/docs/doc/819-2240/iscsitadm-1m?a=view"><em>iscsitadm(1M)</em></a> utility so you can set up things such your custom IQNs, ACLs, CHAP or RADIUS auth, iSNS properties, and so on.</li>
<li><strong>Served Via CIFS.</strong> No, this is <em>not</em> a re-packaged Samba with Solaris-specific tweaks. This is the real deal &#8211; a native, fully integrated <a href="http://opensolaris.org/os/project/cifs-server/">CIFS server</a> that implements the CIFS/SMB LM 0.12 protocol and MSRPC services. It can run in the simple Workgroup mode, or as a member of a Windows AD domain with the full ability to use a domain controller for conferring access and other rights, including the mapping of AD users to UNIX users (so this means that the ZFS or UFS filesystem that comprises a CIFS share can also be exported via NFS in dissimilar environments.) This makes OpenSolaris a truly viable alternative to Windows Server for high-performance, integrated CIFS share serving. Combined with the filesystem management of ZFS, this new CIFS server feature is very compelling. Have a ZFS filesystem that you need exported to some Windows (or Mac, or Linux) boxes? Just like it was with iSCSI, it&#8217;s this simple:<br />
<code>zfs set sharesmb=on pool/my/fs</code><br />
You can set additional share parameters, such as its advertised name by replacing &#8220;=on&#8221; with other arguments. See the section for the <em>set</em> option in the <a href="http://docs.sun.com/app/docs/doc/819-2240/sharemgr-1m?a=view"><em>sharemgr(1m)</em></a> man page. Management of LM users, groups and server mode are accomplished with the separate <a href="http://docs.sun.com/app/docs/doc/819-2240/smbadm-1m"><em>smbadm(1M)</em></a> command.</li>
<li><strong>NDMP Backups.</strong> That&#8217;s right, a new <a href="http://opensolaris.org/os/project/ndmp/">NDMP</a> service is now present for all your enterprise backup needs. Have some of those expensive Legato Networker NDMP licenses to burn, or want back up a NetApp or other NDMP-capable device to a <a href="http://www.sun.com/servers/x64/x4540/">Sun Fire X4540</a> so you can pitch it and its support contract out the window? Fire up the NDMP daemon and go to town with the <a href="http://docs.sun.com/app/docs/doc/819-2240/ndmpadm-1m?a=view"><em>ndmpadm(1M)</em></a> command. This new service in OpenSolaris supports NDMP versions 2, 3, and 4. There is also a nifty way to get statistics on your NDMP sessions with the <a href="http://docs.sun.com/app/docs/doc/819-2240/ndmpstat-1m?a=view"><em>ndmpstat(1M)</em></a> command.</li>
<li><strong>COMSTAR.</strong> Or <a href="http://opensolaris.org/os/project/comstar/">Common Multiprotocol SCSI Target</a>, is quickly becoming the in-kernel nexus of sorts for exporting a generic &#8220;block device&#8221; outside the system over an array of protocols and transports. What this subsystem allows you to do is take a ZVOL and export it over things such as Fibre Channel and FCoE. That&#8217;s right, if you have a system with <a href="http://www.qlogic.com/Products/SAN_products_fibreHBA.aspx">Qlogic QLA/QLE24xx cards</a>, you can <em>turn them into a target rather than an initiator</em> and serve LUNs over FC on your SAN. Your OpenSolaris box is looking like a classic storage array now, but with far more features and flexibility. Fiber Channel over Ethernet (FCoE) is also an option. Future plans include bringing the aforementioned iSCSI server under COMSTAR&#8217;s domain as well. Earlier Qlogic HBAs such as the 2Gb models (QLC23xx) are not supported as targets as those cards lack features required in their firmware to put them in such a mode.</li>
<li><strong>Replicate With AVS.</strong> Sun has offered a filesystem-agnostic block-level replication software suite for some time called StorageTek Availability Suite, or AVS. This was a pay-for product, but Sun has graciously donated it in full to OpenSolaris, so now it is free to use. <a href="http://opensolaris.org/os/project/avs/">AVS</a> allows you to configure synchronous or asynchronous replication over the network to a remote sever, with additional capabilities such as shadow images (termed as &#8220;Instant Image&#8221; in AVS). AVS lives in-kernel, and situates itself between the filesystem (ZFS, UFS, etc) and the disk devices, copying blocks off to their configured destination. <a href="http://opensolaris.org/os/project/avs/Demos/">Here are some demos</a> by lead developer Jim Dunham that demonstrate the use and capabilities of AVS.</li>
<li><strong>SAM-QFS.</strong> As with AVS, <a href="http://opensolaris.org/os/project/samqfs/">SAM-QFS</a> was formerly an unbundled, pay-for product from Sun, but has been open sourced and provided as a integrated part of OpenSolaris. SAM-QFS has two major components &#8211; QFS, which is a SAN-based multi-writer and reader filesystem, and SAM, a <a href="http://en.wikipedia.org/wiki/Hierarchical_storage_management">hierarchal storage management (HSM)</a> system which sits on top of QFS.QFS in particular is found in both the HPC and service provider data center role where multiple nodes require concurrent read/write access to the same file system over fibre channel or iSCSI. It can be utilized in a single-writer setup, where one node can write but all others are read-only, or a multi-writer setup, where &gt; 1 nodes require write access. In the latter case, additional infrastructure is required in the form of a metadata server, the role of which is to manage and coordinate locks and write access amongst the involved nodes.
<p>Along with QFS, there is the SAM component. This allows one to age data off to cheaper bulk storage (cheap SATA arrays) and/or tape-based long term storage.</li>
</ul>
<p>That&#8217;s a snapshot of the major additions, but there are still a lot of smaller projects that have been integrated, or are on the verge of being made available such as pNFS, MMS, ADM, and Honeycomb. As you can see, OpenSolaris offers quite a bit for those looking for highly flexible ways to store, manage, and export data to and from other systems&#8230; and it&#8217;s all <em>built in and fully functional</em>. No licenses or hidden costs.</p>
<p>The <a href="http://opensolaris.org/os/community/storage/">OpenSolaris Storage Community</a> is a great place to keep track of what&#8217;s new, and provides a very nice <a href="http://opensolaris.org/os/community/storage/projects/">visual representation</a> of the various storage layers and components in OpenSolaris.</p>

			<content:encoded><![CDATA[<p>I took this photo of the 1st half Moon while at the April 10 <a href="http://howardastro.org/">HAL</a> star party at Alpha Ridge Park, Maryland.</p>
<p><a href="http://elektronkind.org/photos/astro/moon/moon.png.html"><img src="http://elektronkind.org/gallery2/photos/d/8332-2/moon.png?g2_GALLERYSID=d7cf652c987b6eda027b026311a2e599" width="200"  height="191"  alt="The Moon -  April 10 2008" title="The Moon -  April 10 2008" class="g2image_centered" /></a></p>
<p>Although I&#8217;ve taken many photos through my telescopes, I really consider this one to be my first &#8220;real&#8221; astrophoto, having gone through the motions of equipment setup, settings selections, and a bit of post-processing in Photoshop CS3 for this one shot of the moon.</p>
<p>These two books &#8211; Michael Covington&#8217;s <em><a href="http://www.amazon.com/Digital-Astrophotography-Practical-Amateur-Astronomy/dp/0521700817/ref=pd_sim_b_title_2">Digital SLR Astrophotography</a></em> and R. Scott Ireland&#8217;s <em><a href="http://www.amazon.com/Photoshop-Astronomy-R-Scott-Ireland/dp/0943396859">Photoshop Astronomy</a></em> &#8211; lent me a big hand in teaching me what to do before <em>and</em> after taking a photo or series of photos of an object. I highly recommend them.</p>

			<content:encoded><![CDATA[<p>I accidentally left my trusty 3rd gen 40GB iPod on the plane when I arrived in San Francisco yesterday, so I headed to the Apple Store around the corner from my hotel in downtown SF to treat myself to a new 160GB iPod Classic. I happily bought a silver one, and headed back to the office to christen it and put some music on it.</p>
<p>Apparently I got a lemon :(<br />
<code>Mar 11 15:27:47 cobalt kernel[0]: disk3s2: I/O error.<br />

</code></p>
<p>&#8230; and on and on&#8230; eventually after spending 2 hours syncing only 47 songs (out of 940) did iTunes figure something was wrong and proceeded to beach ball.</p>
<p>Time to see how easy it will be to exchange this one.</p>
