While the $500 SAN platform did not make it under the tree, I have found a significant number of my “wish list” (partially) fulfilled by the technology elves. Heres the breakdown:
1. The $500, 2U, iSCSI SAN… not yet.
2. A F/OSS iSCSI SAN OS with replication, clustering, advanced cache storage and deduplicating backup for $1,000 plus hardware:
Every read or write made by NexentaStor utilizes ZFS data integrity. To avoid accidental and silent data corruption ZFS provides end-to-end checksumming and transactional copy-on-write IO operations. These operations eliminate the ‘write-holes’ and silent data corruption that have plagued storage solutions that are not based on ZFS.
At a higher level, NexentaStor enables you to protect your data through a range of backup and replication capabilities including unlimited incremental snapshot capabilities. Most legacy vendor solutions are limited to 255 snapshots, which limits your freedom when setting up backup and protection schemes for your data. Other open source based solutions offer at most one or two incremental snapshots since Linux based snapshots will spike your CPU with each additional snapshot spiking your CPU that much more.
NexentaStor also offers block-level mirroring via our CDP feature. Now you can easily set up real time mirroring for your disaster recovery and remote backup requirements.
There is no silver bullet that can guarantee the security and integrity of your data. By using NexentaStor you are using an advanced file system, with superior data integrity features, as well as a complete variety of replication, backup and mirroring capabilities to reduce and even eliminate the risk of loosing your organization’s data.
3.A 50W TDP, 8-core Opteron, at 3.2GHz… not going to happen. Perhaps the 6-core “Sao Paulo” chip (scheduled for 2010) will satisfy and be compatible with existing Socket F platforms (very iffy today) bound for production through 2009 (AMD, June 2008 update). It looks like a system update may be required in late 2009 to take advantage of DDR3, HT3 and 6/12-core processors. If all of those improvements are in the offiing – it will be worth the investment.
4. A 1U, dual-node, 2P, eight-core hypervisor chassis… almost. Tyan and Supermicro both have a similar offer without N+1 power (see AMD/ESX and AMD/OracleVM node links, respectively). Either will support 1/2-height PCIe-8 to accommodate the 10Gbps NIC and the Tyan has 4x1Gbps Ethernet built-in (Supermicro only has two). Price on the Supermicro is $1,040 from NewEgg and uses the same MB chipset as the Tyan. Both support SMDC/IPMI with IP/KVM options.
5. An 8-port, 10G switch for $1,000… no way, not yet. Provantage offers the SMC8708L2 for $6,100 and you will still need to pay for XFP’s to populate (say, another $8-24,000 for XFP’s on top and $1,600/ea PCIe cards and associated XFP to use them.) Looks like 10Gbps networking costs at least $2,500 per server port including switching (TCO).
6. Still researching the “magically compatible” hypervisor, but a mix of VMWare and OracleVM within the same physical infrastructure has some real merit… check back later on this one.
