Abstract
Description
各ストレージノードは、1つ以上のストレージサーバーであり、そして各ストレージサーバーは、1つ以上の不揮発性ソリッドステートメモリユニットに接続され、これは、ストレージユニットとも称される。ある実施形態は、各ストレージノード内及び1から8の不揮発性ソリッドステートメモリユニット間に単一のストレージサーバー含むが、この一例は、これに限定されるものではない。ストレージサーバーは、内部通信バスのためのプロセッサ、ダイナミックランダムアクセスメモリ(DRAM)及びインターフェイスと、各電源バスのための配電手段とを含む。ストレージノードの内部では、インターフェイス及びストレージユニットが通信バスを共有し、例えば、ある実施形態では、PCIエクスプレスを共有する。不揮発性ソリッドステートメモリユニットは、ストレージノード通信バスを通して内部通信バスインターフェイスに直接的にアクセスするか、又はバスインターフェイスにアクセスすることをストレージノードに要求する。不揮発性ソリッドステートメモリユニットは、埋め込み型中央処理ユニット(CPU)、ソリッドステートストレージコントローラ、及びある実施形態では、例えば、2−32テラバイト(TB)の大型のソリッドステート大量ストレージを収容する。不揮発性ソリッドステートメモリユニットには、DRAMのような埋め込み型揮発性ストレージ媒体、及びエネルギー貯蔵器が含まれる。ある実施形態では、エネルギー貯蔵器は、停電の場合にDRAMコンテンツのサブセットを安定なストレージ媒体に転送できるようにするキャパシタ、スーパーキャパシタ又はバッテリである。ある実施形態では、不揮発性ソリッドステートメモリユニットは、ストレージクラスメモリで構成され、例えば、DRAMに取って代わり且つ省電力維持装置を可能にする相変化又は磁気抵抗性ランダムアクセスメモリ(MRAM)で構成される。
指すようにする。この動作は、到達可能なストレージノードのセットを入力として含む。到達可能な不揮発性ソリッドステートストレージユニットのセットが変化する場合には、最適なセットも変化する。ある実施形態では、持続値は、現在指定値(常に真)であり、そして計算値は、クラスターが再構成を試みるところのターゲット指定値である。この計算は、到達可能で且つ同じクラスターを構成する不揮発性ソリッドステートストレージ152のセットの存在中にオーソリティに対して最適な不揮発性ソリッドステートストレージ152を決定するのに使用される。又、この計算は、指定の不揮発性ソリッドステートストレージが到達不能であってもオーソリティが決定されるようにオーソリティを不揮発性ソリッドステートストレージのマッピングに記録するピアな不揮発性ソリッドステートストレージ152の順序付けされたセットも決定する。ある実施形態では、特定のオーソリティ168が利用できない場合に、複写又は代用オーソリティ168と協議する。
128ビット以上の識別子を使用して、実際上無限であるようにし、再使用の見込みは、システムの予想寿命より長いと計算される。論理的コンテナからのアドレスは、ある実施形態では、ハイアラーキー形態で割り当てられる。最初に、各不揮発性ソリッドステートストレージ152には、ある範囲のアドレススペースが指定される。この指定範囲内で、不揮発性ソリッドステートストレージ152は、他の不揮発性ソリッドステートストレージ152と同期せずに、アドレスを割り当てることができる。
