Today, I attended a webinar where Pat Gelsinger, President of Information Infrastructure at EMC discussed their concept for a new product based on the Yotta Yotta technology they acquired a few years back. Yotta Yotta’s product was a distributed, coherent caching appliance that had FC front end ports, an Infiniband appliance internal network and both [...]

Essentially, deduplication systems identify duplicate data and only store one copy of such data. [...]
Yesterday, Cleversafe announced new Slicestor(r) 2100 and 2200 hardware using 2TB SATA drives. The standard 2100 1U package supports 8TB of raw data and the 2200 new 2U package supports 24TB of data. In addition, a new Accesser(r) 2100 supports 8GB of ECC RAM, and 2 GigE or 10GbE ports for data access.

One astute reader of our performance reports pointed out that some ESRP results could be skewed by the number of drives that are used during a run. So, we included a database transfers per spindle chart in our latest Exchange Solution Review Program (ESRP) report on 1001 to 5000 mailboxes in our latest newsletter. The chart [...]

This chart shows the top 10 CIFS throughput benchmark results as of the end of last year. As observed in the chart Apple’s Xserve running Snow Leopard took top performance with over 40K CIFS throughput operations per second. My [...]

One problem with this chart is that it really only shows 4 subsystems: HDS and their OEM partner HP; IBM DS5300 [...]

The fact that it uses a 3GB/s SATA interface seems to indicate that Seagate is going after the server market rather than the highend storage market [...]

The two that are of interest to most data centers are both the normalized and un-normalized database transfer (DB xfer) charts. The problem with [...]

Storage problems solved by cloud storage
Dynamic capacity – storage capacity is [...]

Both companies started the same time but one is a ~$14B revenue (‘09 projected) behemoth and the other a relatively successful, but relatively mid-size storage company (Spectra Logic is private and does not report revenues).
